COMPARISON AND EVOLUTION OF PERCEPTUAL AND ACOUSTIC CHARACTERISTICS OF VOICE AFTER SUPRACRICOID PARTIAL LARYNGECTOMY WITH CRICOHYOIDOEPIGLOTTOPEXY

The present prospective study, based on a series of 12 male patients m anaged with supracricoid partial laryngectomy with cricohyoidoepiglott opexy (SCPL-CHEP), was designed ii to compare the perceptual and acous tic parameters before surgery and at 6 months after sugery, ii) to eva luate the evolution of the perceptual and acoustic parameters between 6 and 18 months postoperatively, and iii) to determine the correlation s between the perceptual and acoustic parameters preoperatively and at 18 months postoperatively. The roughness was found to be significantl y worsened after SCPL-CHEP. The jitter, shimmer, noise-to-harmonic rat io, and degree of voiceless increased significantly after SCPL-CHEP. N either acoustic nor perceptual parameters varied significantly between 6 and 18 months postoperatively. Preoperatively, a strong statistical correlation was found between grade, roughness and strain and all aco ustic parameters but F0. Breathiness was statistically correlated with all acoustic parameters but jitter. Postoperatively the only statisti cal correlation noted was between roughness and F0.
