Salivary gland tumors are rare (5% of head and neck tumors), and most commonly (70%) found in the parotid. The larger the salivary gland, the more likely a tumor in that gland is benign. Eighty percent of parotid tumors are benign (55% pleomorphic adenoma, 8% Warthinís), 60% of submandibular, 50% of minor salivary glands, and 10% of sublingual. The older the patient, the more likely the tumor is malignant. The facial nerve (VII) passes through the substance of the parotid gland, dividing the superficial from the deep lobe (there is no anatomic cleavage plane). The marginal mandibular branch of the cervicofacial division can be protected during neck dissection by dividing the facial vessels below it and using them as a sling to elevate the nerve out of harmís way. Damage to the nerve causes the corner of the mouth to droop.

The submaxillary gland in the digastric triangle wraps around the posterior edge of the myelohyoid muscle, and its duct (Whartonís) passes toward the anterior floor of the mouth deep to that muscle.
