Objective: 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.
Study design and setting: 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.
Results: 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.
Conclusions: 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.
Significance: The SF-36, VHI, and VOS provide an important complement to traditional endpoints in the analysis of patients with UVCP.
