Abstract
Thirty patients were treated by tympanic neurectomy, chorda tympanectomy, or both for a variety of conditions. Out of six patients with gustatory sweating treated by tympanic neurectomy, two patients were relieved of symptoms, two were improved, and two remained unchanged. In five cases of benign recurrent painful parotid swelling, only two patients noted improvement in symptoms. Seventeen patients suffered from drooling. Out of 12 postresection head and neck patients, 5 (41%) were improved following such surgery. Two of four cerebral palsy children initially had a good result. However, the long-term follow-up of the patients demonstrated that the drooling recurred. An additional patient who suffered from drooling caused by bulbar weakness following a cerebrovascular accident had fewer problems with salivary secretions postoperatively. The pertinent anatomy and pathophysiology is outlined. The possible reasons for the relatively disappointing results achieved are discussed.
