Quality-of-life assessment in patients with unilateral vocal cord paralysis.

Abstract

Our objective was to identify the impact of unilateral vocal cord paralysis (UVCP) on an individual's quality of life both before and after thyroplasty. This was a prospective observational outcome study of consecutive patients presenting to a laryngology clinic with UVCP. Participants received The Medical Outcomes Study Short Form 36-Item Health Survey (SF-36), the Voice Handicap Index (VHI), and the Voice Outcome Survey (VOS). Patients underwent medialization laryngoplasty with silastic, with or without arytenoid adduction. Outcome measures were repeated after surgery. A review of 45 patients at presentation revealed statistically significant reductions in quality of life as measured by each survey. Marked improvements were noted after surgery. Our preoperative data support a profile of significant general health-related and voice-related limitations caused by UVCP. Patient perceptions improved significantly after the surgical treatment of glottal insufficiency. The SF-36, VHI, and VOS provide an important complement to traditional endpoints in the analysis of patients with UVCP.
