Advances in diagnosis and management of salivary gland diseases.

Salivary glands may be involved in a wide variety of diseases, which may be broadly grouped into (1) inflammatory, (2) noninflammatory, nonneoplastic and (3) neoplastic categories. Most inflammatory and noninflammatory, nonneoplastic diseases should be managed conservatively and symptomatically. The common exceptions are first-arch branchialcleft cysts and calculi. Neoplastic lesions always require resection if that is feasible. For benign tumors, simple excision with a cuff of normal tissue around it will usually suffice. The prevailing trend for treatment of malignant neoplasms is conservatism. No longer is the facial nerve routinely sacrificed. The resection done is dictated by the tumor size and the facial nerve is spared unless directly invaded. Postoperative radiation therapy is increasingly used.
