儿童声门下狭窄的外科治疗方法在文献中多有论述,其方法有:(1)对喉内无损害的高位气管狭窄病例,采用切除狭窄后端-端吻合术。(2)切除前部环状软骨后喉下移并作甲状软骨-气管吻合术,适用于处理声门下狭窄直接累及声门者;但为了保护环甲关节和喉返神经,必须保存环状软骨后板,因而使这种方法的应用受到限制,不能用于后位及环形狭窄的病例。(3)嵌入移植之游离或带血管蒂之舌骨瓣以达到扩大声门下腔的目的,亦有人介绍不切除瘢痕组织而嵌入邻近的自身甲状软骨的方法。(4)粘膜下纤维组织切除后扩大外部软骨架的喉-气管成形术,能将声门恢复到适当大小而不损伤粘膜。
Surgical treatment of children with subglottic stenosis in the literature are more discussed, the methods are: (1) for non-invasive high-grade tracheal stenosis cases, the use of resection of the narrow end-anastomosis. (2) resection of the anterior cricoid cartilage laryngeal down and for thyroid cartilage - tracheal anastomosis, is suitable for the treatment of subglottic stenosis directly involving the glottis; but in order to protect the ring and the recurrent laryngeal nerve, you must save the annular cartilage after the plate, and therefore The application of this method is limited, can not be used for posterior and annular narrow cases. (3) embedded in the free or vascularized tongue hyoid bone flap in order to achieve the expansion of the subglottic purpose, it was also introduced without excision of the scar tissue and embedded in its own way of thyroid cartilage. (4) Laryngeal-tracheal angioplasty, which expands the external cartilage after submucosal fibrous tissue resection, can restore the glottis to the proper size without damaging the mucosa.
