The facial nerve and its branches pass through the parotid gland, as does the external carotid arteryand retromandibular vein. Adjuvant postoperative radiation therapy (RT) can be given in such cases, but this should be discussed in an interprofessional team setting. (2011) Page 22-24. The sensitivity, specificity, and accuracy of US in differentiation of malignant from benign lesions in the parotid gland were 60, 95.2, and 90.3%, respectively. Radiation therapy might be recommended after surgery. Monomorphic adenomas may feel like pleomorphic adenomas but lack the pleomorphic features. The adjuvant approach in this case was decided by a multidisciplinary team given the absence of classically known risk factors. This helps the surgeon decide how much of the parotid gland to remove. The tumor usually presents as a slow-growing mass and tends to spread along nerve sheaths. Partial parotidectomy or hemi-superficial parotidectomy has become commonplace. Benign lesions tend to be more common in women, but malignant lesions tend to occur with equal frequency in both genders. Imaging of salivary gland.

Differential Diagnosis A clinically relevant approach to differentiating neck masses depends on whether the mass is acute, subacute, or chronic ( Tables 1 and 2). Salivary glands are a common source of benign pathology; malignant tumors are rare. This is usually temporary: Permanent facial paralysis is rare.. Sometimes a sample of tumor tissue is tested during surgery to see if it's cancer. It is now generally accepted that an adequate margin in benign tumors, is a cuff of 1 to 2 mm. When this happens, you might experience weakness of your face, or a part of it, on one side. Damage to the facial nerve can occur and is associated with high morbidity.

Low-grade or well-differentiated tumors usually behave benignly, intermediate ones are more aggressive and high-grade, or undifferentiated tumors metastasize early to regional lymph nodes and carry a poor prognosis. The distinction between tumor types can be difficult, particularly based on material from fine-needle aspiration (FNA). Image courtesy S Bhimji MD, Superficial parotidectomy for a benign salivary gland tumor. A prophylactic selective neck dissection (levels I to III) should be performed for patients with high-stage (T3/T4) disease-free clinically high-grade tumors (i.e., high-grade mucoepidermoid carcinoma, carcinoma ex-pleomorphic adenoma, adenocarcinoma, squamous and undifferentiated carcinomas). Salivary gland tumors represent 5%to 10%of tumors within the head and neck.1 Of these, 80% arise from the parotid gland.1 The ability of otolaryngologists to appropriately eval-uate and treat parotid masses is vitally important.
