[Salivary gland diseases].

Only about 1% of head and neck tumors are neoplasms of the salivary glands. The majority [80%] of these tumors are benign. Pleomorphic adenomas, the most frequent benign tumors of the salivary glands, can transform into malignancy, especially after a long duration. Treatment of salivary gland tumors consists of complete surgical excision by a surgeon experienced in microsurgery of the facial nerve. Acute suppurative and viral sialadenitis is usually treated by the general practitioner either symptomatically or, if possible, specifically. Chronic sialadenitis, sialadenosis, Sjögren's syndrome, and Frey's syndrome often need long-term follow-up and medical treatment, which is also usually delivered by the general practitioner, after the diagnosis has been established. Trauma to the salivary gland with transsection of the duct or facial nerve needs immediate microsurgical repair by an otolaryngologist. Sialolithiasis is also treated surgically in most cases.
