Unilateral Vocal Fold Paralysis in Parkinson Disease: Case Report and Review of the Literature.

OBJECTIVE: The objective of this study was to report the first case of unilateral vocal fold paralysis in a patient with Parkinson disease (PD) and to review the literature.

METHODS: This is a case report and literature review following PubMed search using the keywords "Parkinson," "vocal fold paralysis," "vocal fold palsy," "vocal fold immobility," "vocal fold adductor palsy," "airway obstruction," and "stridor."

RESULTS: A total of 18 subjects diagnosed with PD and vocal fold paralysis were described. In all cases, the vocal fold paralysis was bilateral and the main presenting symptoms were stridor and shortness of breath necessitating intubation and tracheostomy. This article describes the first case of PD presenting with dysphonia secondary to unilateral vocal fold paralysis (left). The management consisted of injection laryngoplasty for medialization of the paralyzed vocal fold.

CONCLUSIONS: Patients with PD can present with unilateral vocal fold paralysis. Early treatment is advocated in view of the advent of injection laryngoplasty as a safe office procedure.
