杓状软骨切除术治疗双侧外展肌麻痹所致通气障碍的进路有:喉裂开进路(B aker,1916);喉外进路(Woodm an,1946);内窥镜下喉内进路(Thornell,1948)。Brown(1951)指出,喉内进路较喉外简单,血肿形成和感染率均低,术中容易判断声门裂的大小。作者报道双侧外展肌麻痹喉内进路杓状软骨切除术6例。4例行一侧杓状软骨切除,术后发音通气良好。2例行双侧杓状软骨切除,其中1例通气尚好但发音略差;另一例仍需气管造口。无严重并发症。手术方法:投予抗生素,全麻下行悬吊喉镜检查。未曾气管造口者,手术开始前先行气管造口。按Thornell(1948)氏法切口稍加改进,使呈“T”形。锐分离暴露杓状软骨后用喉钳抓住,继续剥离至杓 Procedures of arytenotomy for the treatment of ventilatory disorders due to paralysis of bilateral abductor abscess include: laryngeal approach (Baker, 1916); extrathoracic approach (Woodm, 1946); endoscopic throat Approach (Thornell, 1948). Brown (1951) pointed out that the laryngeal approach is simpler than throat, hematoma formation and infection rates are low intraoperative evaluation of the size of the glottis. The authors report 6 cases of bilateral ary abductor abscess laryngeal approach arytenotomy. 4 routine side arytenoid cartilage resection, postoperative pronunciation of good ventilation. 2 cases of bilateral arytenoid cartilage resection, including 1 case of good ventilation but poor pronunciation; the other cases still need tracheostomy. No serious complications. Surgical methods: Antibiotics, hanging laryngoscopy under general anesthesia. Tracheostomy stoma have not, before the beginning of tracheostomy. By Thornell (1948) method incision slightly improved, so that the “T” shape. After sharp separation of the arytenoid cartilage exposed to grasp with laryngeal forceps, continue to peel to the dipper
