Taste changes in patients who underwent cochlear implantation by the nonmastoidectomy approach.
OBJECTIVE
To describe taste changes following a nonmastoidectomy approach to cochlear implantation (CI).


METHODS
Retrospective.


METHODS
Ninety-four adult patients (63 females) who underwent CI using the suprameatal approach (SMA) were studied. They responded to a questionnaire on post-CI taste changes, duration of these changes and their influence on eating habits, weight and quality of life.


RESULTS
Fourteen patients (14.9%, all females) reported taste dysfunction (13 ranked as being mild). In 1 patient, the symptoms lasted >24 months, and dysgeusia was counted as permanent in this case. One patient changed her eating habits: she now prefers vegetarian food. The patients with early (<1 month) recovery of taste function were younger than those with delayed recovery.


CONCLUSIONS
The SMA is a favorable technique for the preservation of taste sensation in CI patients. Manipulation on the chorda tympani nerve during the SMA did not much disturb the patients' eating habits and their quality of life.
