Study Summary
Unilateral vocal fold paralysis (UVFP) is caused by injury to the nerve to the affected vocal fold. The injury to the vocal fold makes the affected person's voice sound "breathy". Voice therapy is usually tried first, and, if unsuccessful, surgical treatment is considered. The standard surgical treatment is called vocal fold medialization and aims to bring the injured cord to the midline. An alternative surgical treatment, vocal fold reinnervation, aims to bring a new nerve supply to the injured vocal fold. The reinnervation operation, which has some potential advantages over the medialization operation also requires several months for final results to be gained. The goal of this multicenter, randomized clinical trial is to see which of the two surgical treatments produces a better outcome. In order to participate in this study patients with UVFP must meet all entry criteria and must be released from voice therapy by a speech-language pathologist. Information collected for the study (pre-surgery, and at 6 and 12 months after surgery) includes voice recordings, movies made of vocal fold function, airflow and pressure measurements of the voicebox, and an outcomes questionnaire.
