Abstract

Arytenoid adduction procedures involve approximation of the arytenoid cartilages with the goal of reducing posterior glottal gap size and improving voice. However, voice outcomes after arytenoid adduction are not always optimal and may be improved by precise use of suture placements, forces, and direction angles. The development of intraoperative methods of assessing optimal suture direction appears critical for achieving the best voice outcome. The goal of this study was to examine the relationship of visual classification of glottal configuration, digital measures of the glottis, acoustic and aerodynamic measures, and voice outcome. Our results suggested that visual classification of glottal configuration was not useful in distinguishing voice outcome, except for cases in which there was a large posterior glottal gap. In contrast, acoustic and aerodynamic measures were related to digitized glottal measures and may be developed into a useful method of intraoperative monitoring.
