Salivary Gland Cysts: Causes & Treatment

Cysts in salivary glands represent localized, epithelium-lined cavities that can arise within the major and minor salivary glands, with mucoceles being a frequently observed subtype, particularly in the oral cavity. Sialography, a diagnostic imaging technique, is often employed by healthcare professionals to visualize these cysts and assess their characteristics, aiding in accurate diagnosis and treatment planning. The University of California, San Francisco (UCSF), among other leading medical institutions, conducts extensive research on salivary gland disorders, contributing significantly to the understanding of the etiology and management of cysts in salivary glands. Surgical intervention, guided by techniques refined through evidence-based practices, remains a primary treatment modality, although minimally invasive approaches such as sialendoscopy are increasingly utilized to address specific types and locations of cysts in salivary glands.

Salivary gland cysts represent a spectrum of pathological conditions affecting the salivary glands, critical components of the oral cavity responsible for saliva production. These cysts manifest as fluid-filled sacs within or adjacent to the salivary glands, causing swelling and discomfort. Understanding their nature is the first step towards effective diagnosis and management.

Defining Salivary Gland Cysts and Their Relevance

A salivary gland cyst is defined as an epithelial-lined cavity filled with fluid or semi-fluid material, arising within or near a salivary gland.

They are considered pathological entities due to their potential to cause pain, swelling, and functional impairment.

Furthermore, untreated cysts can lead to secondary infections or complications, underscoring the importance of timely diagnosis and intervention.

The prevalence of salivary gland cysts highlights their clinical relevance, making them a significant concern in oral and maxillofacial pathology.

True Cysts vs. Pseudocysts: A Critical Distinction

A fundamental aspect of understanding salivary gland cysts lies in differentiating between true cysts and pseudocysts.

True cysts possess an epithelial lining, representing a distinct pathological entity with a defined developmental or neoplastic origin.

In contrast, pseudocysts, such as mucoceles, lack an epithelial lining. These typically arise from extravasation of saliva into the surrounding tissues, often due to ductal damage.

Mucoceles, frequently encountered in the lower lip, exemplify pseudocysts resulting from trauma-induced salivary spillage.

The correct classification is crucial as it impacts the choice of treatment and the prediction of recurrence.

Anatomical Location as a Diagnostic Aid

The location of a salivary gland cyst is a critical factor in the diagnostic process. Different types of cysts exhibit a predilection for specific anatomical sites within the oral cavity and related structures.

For example, a ranula, a type of mucocele occurring in the floor of the mouth, typically arises from the sublingual gland.

Cysts located within the major salivary glands, such as the parotid or submandibular glands, may indicate different underlying pathologies compared to those found in minor salivary glands of the oral mucosa.

Careful examination of the cyst's location – whether in the oral cavity, floor of the mouth, lower lip, or salivary gland ducts – provides valuable clues. This directional approach significantly narrows the differential diagnosis and guides further investigations.

Unraveling the Causes: Etiology and Pathogenesis of Salivary Cysts

Salivary gland cysts arise from a complex interplay of factors, with salivary gland obstruction emerging as a primary culprit. Understanding the etiological landscape is crucial for targeted interventions. This section explores the underlying causes and mechanisms behind their formation, examining the role of salivary gland obstruction, different mechanisms involved in ductal blockage, and the distinction between retention and extravasation cysts.

Salivary Gland Obstruction: A Central Mechanism

Obstruction of salivary flow is a pivotal factor in the pathogenesis of many salivary gland cysts.

When the normal drainage pathway for saliva is impeded, a buildup of fluid occurs, leading to the distension of the gland or duct and subsequent cyst formation.

This obstruction can stem from a variety of causes, ranging from physical blockages to functional impairments of the salivary glands.

Mechanisms of Ductal Obstruction

Ductal obstruction can manifest through several distinct mechanisms, each contributing to the development of salivary gland cysts.

Identifying the specific mechanism is crucial for tailoring treatment strategies.

Sialolithiasis: The Role of Salivary Gland Stones

Sialolithiasis, or the formation of salivary gland stones, is a common cause of ductal obstruction.

These mineralized deposits typically consist of calcium phosphate and other organic materials, gradually accumulating within the salivary ducts.

The presence of a sialolith can physically block the flow of saliva, leading to swelling, pain, and ultimately, cyst formation if the obstruction persists.

The submandibular gland is particularly susceptible to sialolithiasis due to the longer, more tortuous path of Wharton's duct, along with the more alkaline and mucin-rich secretions of the gland.

The size of the stone can vary from a few millimeters to several centimeters.

Retention Cysts vs. Extravasation Cysts: A Comparative Analysis

Salivary gland cysts can be broadly categorized as either retention cysts or extravasation cysts, each with a distinct pathogenesis.

Understanding the differences between these types is critical for accurate diagnosis and appropriate management.

Retention cysts arise from the obstruction of a salivary duct, leading to the accumulation of saliva within the ductal system.

This obstruction may be caused by sialoliths, strictures, or other factors that impede the normal flow of saliva.

The cyst is lined by epithelium, representing a true cystic structure.

In contrast, extravasation cysts (like mucoceles) result from the leakage of saliva into the surrounding tissues, typically due to trauma or injury to the salivary ducts.

Unlike retention cysts, extravasation cysts lack an epithelial lining, classifying them as pseudocysts.

The extravasated saliva elicits an inflammatory response, leading to the formation of a granulation tissue wall around the fluid collection.

Sjögren's Syndrome and Salivary Gland Dysfunction

Sjögren's Syndrome, an autoimmune disorder characterized by chronic inflammation of the salivary and lacrimal glands, can significantly impact salivary gland function and contribute to cyst formation.

The inflammatory process in Sjögren's Syndrome can lead to ductal damage and obstruction, predisposing individuals to the development of salivary retention cysts.

Reduced salivary flow, a hallmark of Sjögren's Syndrome, further exacerbates the risk of cyst formation.

The chronic inflammation can also alter the composition of saliva, making it more viscous and prone to stasis, which contributes to obstruction.

Types of Salivary Gland Cysts: A Detailed Overview

Salivary gland cysts present in various forms, each with distinct features influencing diagnosis and treatment strategies. This section provides a detailed examination of key types, including mucoceles, ranulas, and plunging ranulas, highlighting their unique characteristics, prevalence, and anatomical predilections.

Mucocele: Characteristics and Presentation

Mucoceles are among the most frequently encountered salivary gland lesions. They represent a form of salivary extravasation cyst or, less commonly, a retention cyst affecting minor salivary glands.

Prevalence and Location of Mucoceles

Mucoceles exhibit a notable predilection for the lower lip, accounting for a significant proportion of cases. They can also arise on the buccal mucosa, ventral tongue, and floor of the mouth, albeit less frequently.

The prevalence is higher in children and young adults, likely due to increased incidence of minor trauma in these age groups. These age groups are more prone to accidental biting or other injuries to the oral mucosa.

Clinical Presentation and Differential Diagnosis of Mucoceles

Clinically, a mucocele typically manifests as a dome-shaped, fluctuant swelling. It has a bluish or translucent appearance, reflecting the underlying fluid collection.

Superficial mucoceles may rupture spontaneously, leading to temporary relief followed by recurrence. Deep mucoceles present as nodules of normal mucosal color.

Differential diagnosis includes other benign lesions such as lipomas, fibromas, and salivary gland tumors. Vascular lesions like hemangiomas also need to be considered.

Aspiration can aid in diagnosis, yielding a clear, viscous fluid. Histopathological examination confirms the diagnosis by revealing a pseudocyst lacking an epithelial lining, surrounded by granulation tissue and inflammatory cells.

Ranula: Cystic Lesions of the Floor of the Mouth

A ranula is a specific type of mucocele that occurs in the floor of the mouth. It is associated with the sublingual gland or, less commonly, the submandibular gland.

Definition and Location of Ranulas

The term "ranula" is derived from the Latin word for "frog," reflecting the lesion's resemblance to a frog's translucent underbelly. Ranulas are located lateral to the midline in the floor of the mouth.

They are typically unilateral and can vary in size, ranging from a few millimeters to several centimeters. Large ranulas may elevate the tongue and interfere with speech and swallowing.

Distinguishing Features of Ranulas

Ranulas are characterized by their bluish, translucent appearance and their location in the floor of the mouth. This location distinguishes them from other oral lesions.

They are generally painless unless secondarily infected. Palpation reveals a soft, fluctuant mass.

Differential diagnosis includes dermoid cysts, epidermoid cysts, and other salivary gland tumors. Imaging modalities like ultrasound or MRI can assist in differentiating ranulas from other lesions.

Plunging Ranula: Extension into the Neck

A plunging ranula is a variant of the ranula that extends beyond the confines of the floor of the mouth. It plunges through the mylohyoid muscle into the neck.

Extension and Pathogenesis of Plunging Ranulas

The exact mechanism of extension is debated, but it is thought to occur through natural dehiscences in the mylohyoid muscle or via direct erosion. The extravasated mucus then accumulates in the submandibular space or other neck compartments.

Clinical Significance and Diagnostic Considerations

Plunging ranulas typically present as a swelling in the neck, often in addition to a visible ranula in the floor of the mouth. The cervical swelling may be soft and fluctuant or firm, depending on the degree of inflammation and fibrosis.

Clinical significance lies in their potential to cause airway compromise, dysphagia, and cosmetic disfigurement. Diagnosis requires a combination of clinical examination and imaging studies, such as CT or MRI.

These imaging modalities delineate the extent of the lesion and its relationship to surrounding structures. Differential diagnosis includes branchial cleft cysts, thyroglossal duct cysts, and lymphadenopathy.

Careful evaluation is essential to guide appropriate management, which often involves surgical excision of both the oral and cervical components of the cyst.

Distinguishing Salivary Cysts from Other Conditions: Differential Diagnosis

Salivary gland cysts, while relatively common, can mimic other conditions, making accurate differential diagnosis crucial. This process involves systematically considering and excluding alternative diagnoses based on clinical presentation, imaging findings, and, if necessary, histopathological examination. Failure to accurately distinguish a cyst from other pathologies, particularly salivary gland tumors, can have significant implications for patient management and prognosis.

The Importance of a Systematic Approach

Differentiating salivary gland cysts from other conditions requires a systematic approach. This begins with a thorough clinical evaluation, including a detailed patient history and a comprehensive physical examination. The location, size, consistency, and presence or absence of pain or inflammation are all important factors to consider. The duration of the lesion and any associated symptoms, such as difficulty swallowing or speaking, should also be noted.

Ruling Out Salivary Gland Tumors

Excluding salivary gland tumors is paramount in the differential diagnosis of salivary gland lesions. Salivary gland tumors, both benign and malignant, can present as swellings in the oral cavity or neck, similar to salivary cysts. Certain features may raise suspicion for a tumor, such as rapid growth, firmness, fixation to surrounding tissues, and the presence of nerve involvement (e.g., facial nerve paralysis).

Benign salivary gland tumors, such as pleomorphic adenomas, are more common than malignant tumors. However, the possibility of malignancy must always be considered. Imaging studies, such as CT scans or MRIs, are essential for assessing the size, location, and extent of the lesion, as well as for identifying any suspicious features that may suggest malignancy. Fine needle aspiration (FNA) or biopsy may be necessary to obtain tissue for histopathological examination and definitive diagnosis.

Considering Sialadenitis and Other Inflammatory Conditions

Sialadenitis, an inflammation of the salivary glands, is another important consideration in the differential diagnosis of salivary gland lesions. Sialadenitis can be caused by bacterial or viral infections, salivary gland stones (sialolithiasis), or autoimmune disorders.

Acute sialadenitis typically presents with pain, swelling, redness, and tenderness of the affected salivary gland. Purulent drainage from the salivary duct may also be present. Chronic sialadenitis can cause recurrent episodes of pain and swelling or a persistent, firm enlargement of the gland.

Other inflammatory conditions, such as Sjögren's syndrome, can also affect the salivary glands and cause swelling or dryness of the mouth. The diagnosis of sialadenitis is typically based on clinical findings, but imaging studies may be helpful in identifying salivary gland stones or other underlying causes.

Other Less Common Considerations

Besides tumors and inflammatory conditions, other less common entities should be considered in the differential diagnosis of salivary gland cysts. These include:

• Dermoid Cysts and Epidermoid Cysts: These developmental cysts can occur in the floor of the mouth and may resemble ranulas.
• Lymphangiomas and Hemangiomas: These vascular lesions can present as soft, compressible masses in the oral cavity.
• Branchial Cleft Cysts and Thyroglossal Duct Cysts: These congenital cysts typically occur in the neck but can occasionally extend into the oral cavity.

A thorough clinical evaluation, coupled with appropriate imaging studies and, if necessary, tissue biopsy, is essential for accurate diagnosis and appropriate management of salivary gland lesions.

Diagnosis: Tools and Techniques for Identification

Accurate diagnosis is paramount in the effective management of salivary gland cysts. The diagnostic process involves a multi-faceted approach, integrating clinical evaluation with advanced imaging and, in some cases, invasive procedures. A systematic strategy ensures the correct identification and characterization of the cyst, guiding subsequent treatment decisions.

Initial Assessment: Clinical Evaluation and History

The initial assessment hinges on a thorough clinical evaluation. This starts with a meticulous physical examination, encompassing both palpation and visual inspection of the affected area. Palpation allows the clinician to assess the size, consistency, and mobility of the cyst, while visual inspection helps in noting its location, color, and any associated inflammation or ulceration.

Alongside the physical examination, a detailed medical history is indispensable. The clinician must gather information about the patient’s symptoms, including the duration of the swelling, any pain or discomfort, and its impact on daily activities such as eating or speaking. Crucially, the medical history also needs to identify potential risk factors such as prior trauma, infections, or underlying systemic conditions like Sjögren’s syndrome. The importance of detailed medical history cannot be overstated as it can provide valuable clues in narrowing down the differential diagnosis.

Imaging Modalities: Visualizing the Cyst

Imaging techniques play a vital role in confirming the diagnosis and characterizing the cyst's features. Various modalities are available, each with its strengths and limitations.

Ultrasound

Ultrasound is often the first-line imaging modality due to its non-invasive nature, affordability, and accessibility. It provides real-time visualization of the salivary glands and surrounding tissues, allowing for the identification of cysts and assessment of their size, shape, and internal characteristics. However, ultrasound has limitations in penetrating deeper tissues and may not be ideal for evaluating cysts located in the deeper portions of the salivary glands.

Computed Tomography (CT) Scans

CT scans offer a more detailed assessment of the salivary glands, providing excellent bony detail and the ability to visualize the extent of the cyst and its relationship to surrounding structures. This is particularly valuable in assessing larger cysts or those located in complex anatomical regions. Nevertheless, CT scans involve exposure to ionizing radiation and may not be suitable for all patients, especially pregnant women and children.

Magnetic Resonance Imaging (MRI)

MRI is the preferred imaging modality for enhanced soft tissue visualization. It provides superior contrast resolution, allowing for detailed evaluation of the cyst's internal characteristics and its relationship to adjacent nerves and blood vessels. MRI is particularly useful in differentiating cysts from solid tumors and in assessing the presence of any associated inflammatory changes. However, MRI is more expensive than CT scans and may not be readily available in all healthcare settings.

Endoscopy

Endoscopy, specifically sialendoscopy, offers direct visualization of the salivary ducts. This technique involves the insertion of a small endoscope into the salivary duct, allowing the clinician to identify any obstructions, strictures, or other abnormalities. Sialendoscopy can also be used to guide the removal of salivary gland stones or to perform biopsies of suspicious lesions. While minimally invasive, sialendoscopy requires specialized equipment and expertise.

Invasive Diagnostic Procedures: Obtaining Tissue Samples

In certain cases, imaging studies may not provide a definitive diagnosis, necessitating invasive diagnostic procedures to obtain tissue samples for further analysis.

Fine Needle Aspiration (FNA)

Fine needle aspiration (FNA) is a minimally invasive procedure that involves inserting a fine needle into the cyst to aspirate fluid for analysis. The fluid can be examined cytologically to identify any malignant cells or inflammatory components. FNA can also help to differentiate between a true cyst and a pseudocyst.

Biopsy

Biopsy involves the surgical removal of a small tissue sample from the cyst for microscopic examination. Biopsy provides a definitive diagnosis and is particularly useful in cases where malignancy is suspected. The biopsy sample is sent to a pathologist, who examines the tissue under a microscope to determine its cellular composition and identify any abnormalities. Biopsy is essential for confirming the diagnosis and guiding treatment decisions.

Treatment Options: Managing Salivary Gland Cysts

Once a salivary gland cyst has been accurately diagnosed, the focus shifts towards selecting the most appropriate treatment strategy. A variety of therapeutic approaches are available, ranging from conservative measures to more invasive surgical procedures, each tailored to the specific characteristics of the cyst and the patient's overall health. The primary goals of treatment are to eliminate the cyst, alleviate symptoms, prevent recurrence, and preserve salivary gland function whenever possible.

Surgical Interventions for Salivary Cyst Removal

Surgery remains a cornerstone in the management of salivary gland cysts, offering definitive removal and minimizing the risk of recurrence. Several surgical techniques are employed, each with its own advantages and limitations.

Surgical Excision: A Direct Approach

Surgical excision involves the complete removal of the cyst along with its surrounding capsule. This technique is particularly effective for smaller cysts that are easily accessible. The procedure is typically performed under local or general anesthesia, depending on the size and location of the cyst.

Careful dissection is essential to avoid damaging nearby structures, such as nerves and blood vessels. After excision, the surgical site is closed with sutures, and the removed tissue is sent for pathological examination to confirm the diagnosis and rule out any malignancy.

Marsupialization: Creating a Pouch

Marsupialization is a surgical technique that involves creating an opening in the cyst and suturing the edges of the opening to the surrounding mucosa. This transforms the cyst into a pouch-like structure that is continuous with the oral cavity.

This allows the cyst to drain freely and gradually shrink over time. Marsupialization is often preferred for larger cysts, particularly ranulas, as it minimizes the risk of damage to surrounding tissues and structures. It is also an effective method for preventing recurrence.

Micromarsupialization: A Minimally Invasive Alternative

Micromarsupialization represents a minimally invasive modification of the traditional marsupialization technique. It involves using a small suture to create a drainage pathway between the cyst and the oral cavity.

This method is particularly useful for treating mucoceles in children, as it is less traumatic and requires minimal anesthesia. Micromarsupialization offers the advantages of reduced pain, faster healing, and a lower risk of complications compared to traditional surgical approaches.

Salivary Gland Removal: When Necessary

In certain cases, particularly with ranulas, it may be necessary to remove the entire sublingual gland, the gland from which the ranula originates. Sublingual gland excision is indicated when the ranula is large, recurrent, or associated with significant inflammation.

This procedure involves surgically removing the affected gland to eliminate the source of the cyst. While gland removal may result in a slight reduction in salivary flow, the remaining salivary glands typically compensate, and long-term complications are rare.

Alternative Treatment Modalities

In addition to surgical interventions, several alternative treatment modalities are available for managing salivary gland cysts.

CO2 Laser Ablation: Vaporizing the Cyst

CO2 laser ablation is a non-invasive technique that uses a carbon dioxide laser to vaporize the cyst tissue. The laser energy is precisely targeted to the cyst, causing it to shrink and eventually disappear.

This method is particularly useful for treating superficial cysts and mucoceles. CO2 laser ablation offers the advantages of minimal bleeding, reduced scarring, and faster healing compared to traditional surgical techniques.

Medications: Managing Associated Infections and Inflammation

While medications cannot directly eliminate salivary gland cysts, they can play a crucial role in managing associated infections or inflammation. Antibiotics may be prescribed to treat bacterial infections within or around the cyst.

Corticosteroids, either topical or systemic, can help reduce inflammation and swelling, alleviating pain and discomfort. Medications are often used as an adjunct to surgical or other treatment modalities to promote healing and prevent complications.

The Medical Team: Specialties Involved in Salivary Cyst Care

Effective management of salivary gland cysts often necessitates a collaborative approach involving various medical specialists. Their combined expertise ensures accurate diagnosis, targeted treatment, and comprehensive patient care. Understanding the roles of each specialist is crucial for navigating the healthcare landscape when dealing with these cysts.

The Otolaryngologist (ENT Doctor): A Central Figure

The otolaryngologist, also known as an ENT (ear, nose, and throat) doctor, often serves as the primary point of contact for patients with salivary gland cysts.

Their expertise lies in diagnosing and treating disorders of the head and neck, including the salivary glands. The ENT doctor conducts thorough physical examinations, orders relevant imaging studies, and performs initial diagnostic procedures such as fine needle aspiration.

Otolaryngologists are typically the first to assess the nature and extent of the cyst, determining the need for further intervention or referral to other specialists.

The Oral and Maxillofacial Surgeon: Surgical Expertise

When surgical intervention is required, the oral and maxillofacial surgeon plays a critical role. These surgeons specialize in surgical procedures involving the mouth, jaws, and facial structures.

They are highly skilled in performing cyst excisions, marsupialization, and, when necessary, salivary gland removal. Their training emphasizes precision and meticulous technique to minimize complications and preserve the function of surrounding tissues.

Oral and maxillofacial surgeons work closely with other specialists to plan and execute complex surgical cases, ensuring optimal outcomes for patients.

The Pathologist: Unraveling the Microscopic Details

The pathologist is an essential member of the diagnostic team. After a cyst is surgically removed or biopsied, the tissue sample is sent to the pathologist for microscopic examination.

Through careful analysis, the pathologist confirms the diagnosis, differentiates between various types of cysts, and rules out any signs of malignancy.

The pathologist's report provides critical information that guides treatment decisions and helps determine the prognosis. Their expertise in interpreting cellular abnormalities is invaluable in ensuring accurate and appropriate management.

The Radiologist: Visualizing the Unseen

Radiologists employ various imaging techniques to visualize the salivary glands and surrounding structures. They are experts in interpreting X-rays, CT scans, MRIs, and ultrasounds, providing crucial information about the size, location, and characteristics of the cyst.

Their insights aid in differential diagnosis, treatment planning, and monitoring the response to therapy. Radiologists often collaborate with other specialists to select the most appropriate imaging modality and ensure accurate interpretation of the results.

The Dentist: Early Detection and Preventative Care

While not always directly involved in the surgical management of salivary gland cysts, dentists play a crucial role in early detection and preventative care. During routine dental examinations, dentists may identify suspicious lesions or abnormalities in the oral cavity, prompting further investigation.

They can also educate patients on oral hygiene practices to minimize the risk of salivary gland duct obstruction and subsequent cyst formation. Dentists work in conjunction with other specialists to provide comprehensive oral healthcare and address any potential complications related to salivary gland cysts.

Essential Tools and Materials: A Brief Overview

The diagnosis and treatment of salivary gland cysts rely on a specific set of instruments and materials. These tools facilitate accurate assessment, precise surgical intervention, and effective postoperative care. This section provides a concise overview of the most essential items used in managing salivary gland cysts, offering insight into their practical applications.

Scalpels: The Foundation of Surgical Precision

The scalpel, a fundamental surgical instrument, is indispensable for making incisions and excising cysts. Different blade shapes and sizes cater to varying surgical needs and anatomical locations.

Sterile scalpels are crucial for maintaining aseptic conditions and preventing infection during surgical procedures. The surgeon's skill in using the scalpel directly impacts the precision and success of the cyst removal.

Sutures: The Art of Tissue Approximation

Sutures are essential for closing incisions, approximating tissues, and promoting wound healing after cyst removal. Suture materials vary in composition (e.g., absorbable vs. non-absorbable) and size, each suited for specific tissue types and wound characteristics.

The choice of suture material and suturing technique plays a critical role in minimizing scarring and ensuring proper wound closure. Proper suture placement is vital for optimal healing and preventing complications such as dehiscence.

Needles and Syringes: Diagnostic and Therapeutic Applications

Needles and syringes serve multiple purposes in the management of salivary gland cysts. They are used for fine needle aspiration (FNA) to collect fluid samples for cytological analysis. This helps in differentiating between cystic and solid lesions.

Additionally, needles and syringes are utilized for injecting medications, such as corticosteroids, directly into the cyst or surrounding tissues to reduce inflammation. The size and gauge of the needle are carefully selected based on the specific procedure and the viscosity of the fluid or medication being administered.

Endoscopes: Visualizing the Salivary Ducts

Endoscopes, particularly sialoendoscopes, represent a significant advancement in the diagnosis and treatment of salivary gland disorders. These thin, flexible instruments are equipped with a camera and light source, allowing for direct visualization of the salivary ducts.

Endoscopy enables the identification of obstructions, such as sialoliths (salivary stones), strictures, or other abnormalities within the ductal system. Furthermore, endoscopes can be used to guide minimally invasive procedures, such as stone removal or dilation of narrowed ducts, offering a less invasive alternative to traditional surgery. Sialoendoscopy provides invaluable insights into the condition of the salivary ducts.

So, there you have it! While finding a lump might be scary, remember that cysts in salivary glands are often benign and treatable. Don't hesitate to see your doctor if you notice anything unusual – early detection and the right approach can make all the difference in keeping your salivary glands happy and healthy.
