The comparison of arytenoid resection surgical effect between endoscopic laser approach and external cervical approach for bilateral vocal cord fold paralysis / 临床耳鼻咽喉头颈外科杂志

ABSTRACT

OBJECTIVE@#To investigate the surgical effect and complications of arytenoid resection in bilateral vocal cord fold paralysis(BVFP) patients via endoscopic laser approach and external cervical approach.@*METHOD@#A total seventy-eight BVFP patients who underwent arytenoid resection surgery via endoscopic laser approach (laser group, n=30) or external cervical approach (external cervical group, n=48) were enrolled in this study. Videostroboscopy, vocal perception evaluation, maximum phonation time (MPT) text were preformed in all patients both preoperatively and postoperatively. The decannulation rate was also calculated.@*RESULT@#Videostroboscopy showed that vocal fold on the operated side in both groups could abduct to various extent postoperatively, which showed significant difference when compared with preoperative abductive movements (P 0. 05). Postoperative videostroboscopy showed no significant difference in vocal fold position and glottal closure between these two groups(P>0. 05). Vocal perceptual evaluation(RBH score) showed a significant deterioration in voice quality postoperatively in both groups respectively (P. 05). However, they were significantly shorten/shorter than preoperative ones in these two groups respectively (P<0. 05). The overall decannulation rate were 90. 0% and 95. 8% for laser group and external cervical group respectively. In Both groups, patients presented aspiration symptoms postoperatively, except one patient of external cervical group who developed pneumonia due to recurrent aspiration.@*CONCLUSION@#Arytenoid resection surgery via both endoscopic laser approach and external cervical approach can both enlarge glottic area so as to solve respiration problems, in BVFP patients. Two kinds of surgery have obvious voice damage.
