Abstract OBJECTIVES: To measure the health-related quality of life (QoL) of patients undergoing conservative management of a vestibular schwannoma and to identify audiovestibular factors that influence health-related QoL. STUDY DESIGN: Cross-sectional case-control study. INTERVENTION: Adult patients undergoing conservative management of a sporadic vestibular schwannoma were identified from a prospectively updated database. Each patient was asked to complete a series of questionnaires, including the Short Form 36 health-related QoL instrument, the Hearing Handicap Inventory, the Tinnitus Handicap Inventory, and the Dizziness Handicap Inventory. The QoL data obtained were compared with UK normal data. Multiple linear regression was performed to identify audiovestibular factors influencing QoL. PATIENTS: Of 241 patients still undergoing conservative management, 165 completed the questionnaires. The mean age was 66.6 years. Mean duration of follow-up was 5.7 years. RESULTS: Physical component summary scores were significantly lower than those of the normal population. Mental component summary scores were significantly above the normal population. Regression analysis showed that dizziness handicap score and age were strong predictors of physical component summary (both p < 0.0001). Dizziness handicap score and tinnitus handicap score were significant predictors of mental component summary (p = 0.0004 and p = 0.027 respectively). However, the model only explained a small amount of the data, suggesting that there may be other factors influencing QoL. CONCLUSION: Dizziness is the most significant audiovestibular predictor of QoL in patients with vestibular schwannomas. Tinnitus also has an impact on mental QoL. Hearing loss does not seem to influence QoL. Other factors such as illness perception may have an important role to play in determining QoL.
