L. Crevierbuchman et al., COMPARISON AND EVOLUTION OF PERCEPTUAL AND ACOUSTIC CHARACTERISTICS OF VOICE AFTER SUPRACRICOID PARTIAL LARYNGECTOMY WITH CRICOHYOIDOEPIGLOTTOPEXY, Acta oto-laryngologica, 118(4), 1998, pp. 594-599
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.
