| The present prospective study, based on a series of 12 male patients managed with supracricoid partial laryngectomy with cricohyoidoepiglottopexy (SCPL-CHEP), was designed ii to compare the perceptual and acoustic parameters before surgery and at 6 months after sugery, ii) to evaluate the evolution of the perceptual and acoustic parameters between 6 and 18 months postoperatively, and iii) to determine the correlations between the perceptual and acoustic parameters preoperatively and at 18 months postoperatively. The roughness was found to be significantly worsened after SCPL-CHEP. The jitter, shimmer, noise-to-harmonic ratio, and degree of voiceless increased significantly after SCPL-CHEP. Neither 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 acoustic parameters but F0. Breathiness was statistically correlated with all acoustic parameters but jitter. Postoperatively the only statistical correlation noted was between roughness and F0. |
