先天性喉蹼多发生于喉前连合处,位于杓状软骨间者仅占喉蹼中之1～2%,并认为症状多不显著,不需特殊处理。作者对1976～1990年间16例杓间喉蹼患儿的资料进行分析,其结果与以往报道不尽相同。16例中有12例出生时即有呼吸困难,另4例也于1周内先后出现呼吸道阻塞症状。喉镜检查除见杓间有膜状组织外,伴有喉部其它发育异常者14例,其中杓状软骨明显增大9例,声门下狭窄8例。16例中有10例还伴非呼吸系统的发育异常(如先天性心脏病等),其中5例有多发性畸形。因 Congenital laryngeal webs occurred in the anterior commissure, located in the arytenoid cartilage between only 1 to 2% of throat webbed, and that the symptoms were not significant, without special treatment. The authors analyzed the data of 16 cases of laryngeal webs from 1976 to 1990, the results of which were different from previous reports. Twelve of the 16 patients had dyspnea at birth, and the other four also had respiratory blockages one week later. Laryngoscopy in addition to see the film between the tube tissue, accompanied by other laryngeal dysplasia in 14 cases, including arytenoid cartilage was significantly increased in 9 cases, subglottic stenosis in 8 cases. Of the 16 cases, 10 also had non-respiratory dysplasia (such as congenital heart disease), of which 5 had multiple deformities. because
