[Taste disorders following ear surgery (author's transl)].
A prospective study of chorda tympany was carried out on 76 patients aging from 14 to 71 years by performing qualitative taste examination and electrogustometry prior to and at regular intervals up to 1 year after tympanoplasty. In 16 cases of preoperative ageusia, the chorda tympany was found to have been destroyed by cholesteatoma or during a previous ear surgery. Out of 27 cases, in which the chorda tympany remained intact during the surgery, nine patients suffered a mild hypogeusia up to 3 months after the operation. In 13 cases, in which the chorda tympany was stretched or distended during the operation, there existed a marred correlation between the degree of its manipulation and the electrogustometric abnormalities. A chorda tympany section was always followed by a postoperative ageusia.
