Purpose: To evaluate tinnitus and its management in patients with vestibular schwannoma (VS) who underwent surgery, we investigate the effect of surgical approach or residual hearing on tinnitus severity and the effects of intervention for tinnitus including educational counseling, sound therapy using hearing aids (HAs), and medication (selective serotonin reuptake inhibitors, and SSRIs). Methods: Seventy-one subjects of VS patients who underwent surgery were included. Their tinnitus severity was evaluated using the Japanese version of the Tinnitus Handicap Inventory (THI). The relationships between postoperative THI scores and surgery types or residual hearing levels were examined. We also examined longitudinal changes in THI scores and the efficacy of the intervention. Results: Surgery approach, hearing preservation or hearing loss surgery, and residual hearing levels were not significantly related to the postoperative tinnitus severity. In 71 cases, 45 cases did not require any management for tinnitus. On the contrary, 26 patients had at least one episode of tinnitus distress (THI score was greater than or equal to 18). Educational counseling alone was found to be effective in 17 cases out of the 26 cases, and the remaining 9 cases required more intervention than educational counseling alone. We selected sound therapy with HA for 7 cases and administration of SSRI for 2 cases, which was found to be highly effective in 8 cases. Conclusion: Based on the present study, we consider that appropriate management may be possible for tinnitus in the majority of VS patients who underwent surgery.
