  Purpose
The goal of this study is to further study the role of LEMG in accurately predicting the recovery of vocal function as well to study the timing of a change of LEMG activity prior to such return of function. We aim to do this by collaborating with several active pediatric otolaryngological practices throughout the country who in turn have agreed to evaluate infants and children with vocal fold immobility who fit a standardized inclusion and exclusion criteria by means of a standardized LEMG protocol over a one year period of time. Our particular goal is to collect and then review information over a one year period of time on all children evaluated for vocal fold immobility by means of LEMG.
