Dysphagia as a predictor of voice handicap and voice restoration in unilateral vocal fold immobility.

ABSTRACT

OBJECTIVE: Dysphagia is multifactorial in unilateral vocal fold immobility (UVFI). Severe dysphagia could indicate greater functional deficits in UVFI. The purpose of this study is to evaluate the association of dysphagia with the need for surgical voice restoration in patients with UVFI. STUDY DESIGN: Retrospective chart review. SETTING: Single-institution, tertiary referral center. METHODS: Records of UVFI patients from 2008 to 2018 were examined. Dysphagia severity was extracted from patient history. Etiology of UVFI and other relevant variables were analyzed to determine their association with dysphagia. Dysphagia severity and other clinical variables were then analyzed for their association with surgical voice restoration. RESULTS: Eighty patients met selection criteria out of 478 patients with UVFI. There was significant concordance between dysphagia severity extracted from patient history and patient-reported EAT-10 scores (R = 0.59, p = 0.000035). Patients' EAT-10 scores were correlated with VHI-10 scores (R = 0.45, p = 0.011). Severe dysphagia (p = 0.037), high VHI-10 score on presentation (p = 0.0009), and longer duration of hoarseness before presentation (p = 0.008) were associated with surgical voice restoration in UVFI patients. CONCLUSION: In this pilot study, severe dysphagia and increased voice handicap on presentation were associated with the need for surgical voice restoration in UVFI patients. Presenting dysphagia may be an additional variable for clinicians to consider for management of UVFI.
