Three subjects of post-hemilaryngectomy/glottic reconstruction status participated in this study. Two subjects had undergone a hemilaryngectomy accompanied by epiglottic laryngoplasty, while the remaining subject had undergone a hemilaryngectomy accompanied by sternohyoid muscle flap reconstruction. The first of the two purposes of the study was to objectively measure the following five vocal parameters: maximum phonation time, intensity, fundamental frequency of sustained phonation, fundamental frequency and range of fundamental frequency of contextual speech, and pitch range. The second purpose of the study was to provide Speech Pathologists with a protocol task continuum for future studies. Results of analysis procedure's revealed that all subjects fell below the mean on all tasks as compared to previously reported performances by normal subjects. Results are reported and discussed using a case study-type approach.
