- Abstract
- Background and Objectives Laryngeal electromyography (LEMG) is valuable for theprognosis of vocal fold paralysis (VFP). However, there is a lack of reliable data to apply it toclinical practice. The aim of this study is to evaluate the reliability of interference pattern ofLEMG in order to predict the prognosis of VFP by comparing interference pattern and vocalcord mobility.
Subjects and Method A retrospective chart review was performed for patients who underwentLEMG from January 2012 to October 2015. Gender and age of patients, cause and treatmentof VFP, vocal cord mobility, and result of LEMG were analyzed. The interference patternof LEMG was used as a predictive marker of prognosis, which is compared with vocalcord mobility during the last follow-up.
Results F ifteen patients were enrolled in this study. Among them, five patients were predictedby LEMG evaluation to have good prognosis, and 10 patients were predicted to havepoor prognosis. All of the five patients with good prognosis showed improvement in vocalcord mobility, while seven out of 10 patients predicted with bad prognosis showed vocal foldfixation at the last follow-up. The reliability of prognostic prediction through interference patternwas 80%.
Conclusion Interference pattern of LEMG is reliable data to predict the prognosis of VFP,especially it showed perfect consistency for good prognosis.
