The major types of salivary glands are the parotid glands, submandibular glands and sublingual glands. There are also a large number (600-1,000) of minor salivary glands widely distributed throughout the oral mucosa, palate, uvula, floor of the mouth, posterior tongue, retromolar and peritonsillar area, pharynx, larynx and paranasal sinuses. Tumours affecting salivary glands may be benign or malignant and are diverse in their pathology. About 80% of salivary gland cancers occur in the parotid gland1 .
