Multidimensional Evaluation of Vocal Function after Supracricoid Laryngectomy with Cricohyoidopexy

Abstract

The aim of this study was to assess the vocal outcome and the impact of arytenoid resection on vocal function following supracricoid laryngectomy with cricohyoidopexy. Twenty-eight male patients who had undergone supracricoid laryngectomy with cricohyoidopexy were included in the study. In 7 patients, one arytenoid cartilage had been totally resected; in 11, both arytenoid cartilages had been preserved; and in 10, one arytenoid cartilage had been partially resected. The maximum phonation time, fundamental frequency, jitter, shimmer, and noise-to-harmonics ratio were assessed and analyzed. Perceptual analysis was performed with the grade, roughness, breathiness, asthenia, and strain (GRBAS) scale. Abduction-adduction and anteroposterior squeezing actions were analyzed from videoendoscopic records. The Voice Handicap Index-10 (VHI-10) was used for self-assessment. The acoustic and aerodynamic parameters and GRBAS score showed severe impairment. The self-assessment revealed that patients were relatively satisfied with their voice quality. There were no statistically significant differences in the acoustic and aerodynamic parameters, the GRBAS score, or the VHI-10 score according to the level of arytenoid resection. Supracricoid laryngectomy with cricohyoidopexy caused deterioration of acoustic and aerodynamic voice parameters and the GRBAS score. Statistically, the level of arytenoid resection had no apparent effect on the objective, perceptual, or subjective voice parameters.
