The patient's perspective after vestibular schwannoma removal: quality of life and implications for management.

A postal survey was conducted, using a standardized quality of life questionnaire, of patients who had undergone surgery for removal of vestibular schwannoma between 1981 and 1992. Of 257 questionnaires, 227 (88%) were returned completed. The questionnaire was based on the European Organisation for Research into the Treatment of Cancer (EORTC) core questionnaire. A series of five functional gradings were used to assess the quality of life, and specific questions were also asked. The results were numerically scored and have been correlated with patient and tumor characteristics. There was a significant difference (p = .0001) between the subjective functional outcome for small and intracanalicular tumors when compared with tumors larger than 1.5 cm maximum diameter. However, there was no significant difference when tumors 1.5 to 2.5 cm in diameter were compared to larger tumors. Poor functional outcome did not correlate with the age of the patient, position in the series, or postoperative facial nerve motor function. There also was no significant difference when younger patients (age < 65 yr) were compared with older patients (age 65 - 76 yr). In general, the quality of life following vestibular schwannoma surgery was excellent. Patients with a poor functional outcome were evenly distributed over the medium and large tumor size groups, and patients with small tumors ( < or = 1.5 cm) had a significantly better outcome.
