[Minor functional disorders after surgery of acoustic nerve neuroma]

Acoustic neuromas must be removed surgically, otherwise serious complications may occur. Removal of an acoustic neuroma most often leads to disorders of balance, hearing, and sometimes facial motor function. Many earlier studies have approached the hearing and facial motor function. However, the facial nerve also comprises sensory and secretory fibers which, when injured, may produce minor disorders affecting patient's quality of life. The purpose of this work was to evaluate the quality of life, secretory and taste disorders after acoustic neuroma surgery.

Among patients operated on between May 1985 and May 1996, we selected only those who presented a normal facial function 3 months after surgery. We thus selected 93 patients and sent them a questionnaire in December 1997. We received 74 answers.

The period between the operation and the dispatch of the questionnaire was on an average 5.5 years (range 19 months-12 years 9 months). Impairment of quality of life was frequent (59% of cases), and changing way of life less so (30%). 74% of the patients described balance disorders. One-quarter of the patients indicated they experienced disorders of facial mobility. Only 3 patients had no disorder.

Secretory and taste disorders are frequent after neuroma surgery. Despite their mildness, patients should be advised accordingly because of possible impact on quality of life. This study also points out the lack of precision in the estimation of facial mobility. A better evaluation of patient complaints would be useful.
