Basic and clinical research for surgical treatment of unilaterallaryngeal paralysis aiming at reinnervation of the laryngeal muscle

喉返神经切断后立即植入神经肌蒂（NMP）瓣，有利于失神经的甲杓肌的神经再支配。此外，NMP植入在长期失神经支配的甲杓肌营养变化的恢复中是有效的。在研究期间，作者对10例患者施行了杓状软骨内收术，对32例患者施行了NMP皮瓣植入联合杓状软骨内收术。后一组患者的发音功能随时间而改善，大多数患者在喉麻痹发作前自行恢复发音。

The nerve-muscle pedicle (NMP) flap implantation immediately aftertransection of the recurrent laryngeal nerve facilitated reinnervation of the denervatedthyroarytenoid muscle. Further, NMP implantation was effective in the recovery fromatrophic changes in long-term denervated thyroarytenoid muscle. The authors performedarytenoid adduction in 10 patients and NMP flap implantation combined with arytenoidadduction in 32 patients during research period. The latter patient group showedtime-dependent improvement of vocal function and most of them retrieved their own voicesbefore the onset of laryngeal paralysis.
