Common Salivary Gland Disorders
The salivary glands comprise of the parotid, submandibular, and sublingual glands, and other minor unnamed glands within the oral cavity. They play a vital role in producing saliva, which aids in digestion and keeps the mouth moist. Disorders of these glands can lead to significant discomfort and other complications. Here, we explore common salivary gland conditions such as stones, tumors, and autoimmune causes of salivary gland swellings.
A. Salivary Gland Stones (Sialolithiasis)
Clinical Presentation
The salivary glands comprise of the parotid, submandibular, and sublingual glands, and other minor unnamed glands within the oral cavity. They play a vital role in producing saliva, which aids in digestion and keeps the mouth moist. Disorders of these glands can lead to significant discomfort and other complications. Here, we explore common salivary gland conditions such as stones, tumors, and autoimmune causes of salivary gland swellings.
Causes and Risk Factors
Salivary gland stones are formed by the deposition of calcium salts. Factors contributing to their formation include reduced salivary production, obstructed flow within the salivary duct, and increased calcium concentration in the saliva. Certain medications that reduce saliva production, a history of previous trauma or instrumentation to the gland, and factors causing dehydration can also increase the risk of developing salivary gland stones (sialolithiasis).
Investigation Modalities
Diagnosis is often clinical, supported by imaging techniques. Ultrasound is commonly used due to its high sensitivity and non-invasive nature. Sialography, a special type of X-ray with contrast dye, and CT scans can also help in identifying salivary gland stones, especially those not visible on ultrasound.
Treatment Options
Small salivary gland stones may be managed conservatively with hydration, warm compress and massages, and sialogogues (substances that stimulate saliva production). Larger salivary gland stones may require more invasive procedures such as sialendoscopy (endoscopic removal) or surgery. Lithotripsy, the use of shock waves to break up salivary gland stones, is another option.
B. Salivary Gland Tumors
Clinical Presentation
Salivary gland tumors can be benign or malignant, with the parotid gland being the most common site. Benign tumors, such as pleomorphic adenomas, present as painless, slow-growing masses. Malignant tumors, like mucoepidermoid carcinoma, may present with rapid growth, pain, facial nerve palsy, or ulceration.
Causes and Risk Factors
The exact cause of salivary gland tumors is unknown. Risk factors include radiation exposure, certain viruses (e.g., Epstein-Barr virus), and genetic predispositions. Smoking has been implicated in some cases.
Investigation Modalities
Evaluation begins with a thorough clinical examination and imaging. Ultrasound, MRI, and CT scans help in assessing the tumor’s size, extent, and characteristics. Fine-needle aspiration biopsy is often used to obtain a tissue sample for cytological examination.
Treatment Options
Treatment depends on the tumor type, size, location, and whether it is benign or malignant. Surgical removal is the primary treatment for both benign and malignant tumors. Malignant tumors may require additional treatments like radiotherapy and, in some cases, chemotherapy. Close follow-up is essential to monitor for recurrence or metastasis.
C. Autoimmune Causes (Sjogren’s Syndrome)
Clinical Presentation
Sjogren’s syndrome, an autoimmune disorder, primarily affects the salivary and lacrimal glands, leading to dry mouth (xerostomia) and dry eyes (xerophthalmia). Patients may also experience swelling of the parotid glands and systemic symptoms such as fatigue and joint pain.
Causes and Risk Factors
Sjogren’s syndrome is caused by the immune system attacking the glands that produce saliva and tears. It is more common in women and often associated with other autoimmune diseases like rheumatoid arthritis and lupus.
Investigation Modalities
Diagnosis involves a combination of clinical evaluation, blood tests (looking for specific autoantibodies like anti-Ro/SSA and anti-La/SSB), and imaging studies. A salivary gland biopsy may be performed to confirm lymphocytic infiltration, a hallmark of the disease.
Treatment Options
Treatment focuses on symptom management. Artificial saliva and tear substitutes can relieve dryness. Immunosuppressive drugs, such as corticosteroids and hydroxychloroquine, are used to control systemic inflammation. Pilocarpine and cevimeline may be prescribed to stimulate saliva production.
