Abstract:
OBJECTIVE To study the therapeutic effect of arytenoid within-shift combining with recurrentlaryngeal nerve (RLN) anastomosis to ansa cervicalis for patients with long-term unilateral vocal cord paralysis (UVCP) . METHODS Twelve patients with traumatic RLNs paralysis were studied. The courses of injury varied from 3 to 22 years. RLN was anastomosed to ansa cervicalis and arytenoid was within-shifted on ipsilateral side in all patients. Therapeutic efficacy was evaluated by laryngoscope, strobe-laryngoscope, voice evaluation, voice acoustics parameter analysis, and laryngeal electromyography (LEMG) . RESULTS The voice was improved in all cases after arytenoid within-shift immediately. The mean values of voice acoustics parameters (jitter, shimmer, NNE) were significantly smaller and maximum phonation time (MPT) were significantly longer after operation compared with those of before treatment. Laryngoscope showed that arytenoid was significantly within-shifted. The glottic posterior chink vanished in 9 cases and reduced in 3 cases. The voice resumed normal, obviously improved, improved and no improved were found in 9、 3、0、0 cases respectively 12 months after operation. The mass and tension of all treated vocal cords may become the same as the contralateral normal vocal cords, thus resuming symmetric vibration of the vocal cords. The reinnervation of the RLNs were approved by LEMG in these patients whose RLNs were restored. CONCLUSION Arytenoid within-shift combining with RLN anastomosis to ansa cervical can restored normal voice in patients with long-term UVCP.
