Abstract

Objective: To track quantitative laryngeal electromyography (LEMG) and voice outcome survey (VOS) changes over 12 months postiatrogenic unilateral vocal fold paralysis (UVFP). To explore the factors influencing these changes.

Study design: Historical cohort study.

Setting: Tertiary medical center.

Methods: Patients who developed UVFP after surgery underwent a series of assessments, including quantitative LEMG, videolaryngostroboscopy, voice acoustic analysis, and completion of the VOS at diagnosis and at the 12-month follow-up. The subsequent data from these assessments were then compared for analysis. Bivariate analysis examined predictors of changes in VOS and LEMG data respectively, with significant factors further included in a multivariate regression model.

Results: The study enrolled 99 patients. LEMG data were prospectively collected within 3.9 months (±SD: 0.2) postsurgery, followed by an average 13.2-month (±SD: 0.2) follow-up. A worse initial turn ratio of thyroarytenoid-lateral cricoarytenoid muscle correlated with more significant subsequent improvement in LEMG findings, reflecting a similar trend observed in the change of VOS scores.

Conclusion: This study contributes valuable insights into the temporal change of quantitative LEMG and VOS in patients with iatrogenic UVFP. It suggests that poor initial LEMG and VOS results do not necessarily determine a worse prognosis in terms of electrical activity.

期刊介绍: Otolaryngology–Head and Neck Surgery (OTO-HNS) is the official peer-reviewed publication of the American Academy of Otolaryngology–Head and Neck Surgery Foundation. The mission of Otolaryngology–Head and Neck Surgery is to publish contemporary, ethical, clinically relevant information in otolaryngology, head and neck surgery (ear, nose, throat, head, and neck disorders) that can be used by otolaryngologists, clinicians, scientists, and specialists to improve patient care and public health.
