Abstract

Objectives: In the management of vestibular schwannoma (VS), patient-perceived outcomes should be given as much attention as physician-reported objective outcomes. Concomitant symptoms can be annoying for sufferers, lowering quality of life (QoL). However, it is difficult to determine the degree to which these symptoms lower QoL using only objective measures. The Penn Acoustic Neuroma Quality of Life Scale (PANQOL) is a validated disease-specific questionnaire commonly used to assess QoL in VS patients. It was developed and published in English. In this study, we translated the PANQOL questionnaire into Japanese and validated its reliability and utility. We also evaluated patient factors that could influence PANQOL scores. Study Design: Cross-sectional study. Methods: Seventy-two VS patients monitored conservatively were included in this study. They were assessed using the Japanese versions of PANQOL (PANQOL-J) and questionnaires about specific symptoms related to VS. The PANQOL questionnaire was translated into Japanese according to the accepted standards. The reliability and utility of the PANQOL-J questionnaire, as well as the relationship with VS-specific symptoms, were statistically analyzed. Results: The mean total score was 78.7. Almost all of its domains had good internal consistency. Most PANQOL-J domains were related to those of the Short Form-36, with the exception of facial dysfunction domain. Scores of all PANQOL-J domains were comparable to scores of other questionnaires related to the VS-specific symptoms. Our analyses indicated tinnitus or facial palsy might affect the PANQOL-J total score. Conclusions: We confirmed the validity of the Japanese version of PANQOL questionnaire and its reliability and utility in the management of VS symptoms concerning facial function.
