甲状软骨侧切术治疗声门旁间隙病变

目的：探讨经一侧甲状软骨板入路行声门旁间隙手术的可行性和优越性。方法：3例位于声门旁间隙的喉黏液囊肿患者，采用一侧甲状软骨“U”形部分切除术入路切除囊肿；1例喉外伤声门旁间隙异物采用一侧甲状软骨板垂直切开取出异物。结果：3例喉黏液囊肿患者随访1年均无复发，声音恢复正常状态；1例喉外伤异物患儿术后双侧声带运动正常，声门闭合良好。结论：经一侧甲状软骨板切开或部分切除入路，可清晰显露声门旁间隙，在直视下彻底切除囊肿或取出异物，手术创伤小，不破坏喉的框架结构，不损伤喉黏膜，术后无并发症，是处理声门旁间隙良性病变的理想手术方式。

Lateral thyrotomy approach on the paraglottic space disease

Objective:To discuss the feasibility and superiority of lateral thyrotomy approach on the paraglottic space operation.Method:Five cases mucocele of larynx located at paraglottic space were resected the cyst completely by a U shaped lateral thyrotomy approach.One cases of laryngeal trauma foreign body in paraglottic space was taken out by approach through vertical split of the thyroid lamina.Result:Three cases mucocele of larynx located did not recurrent during follow up 1year and their phonation were recoverd normally. The other two cases are during follow up.One cases of laryngeal trauma foreign body has been oprated , her vocal cords moved normally and the glottic could be closed completely.Conclusion:Through lateral thyroid lamina split or partial resection approach,the paraglottic space can be exposed clearly and the cyst or foreign body can be easily removed under direct visualization.The operation provides minimal trauma without deformity in laryngeal framework,and postoperative complication to enter the laryngeal mucosa.It proves to be an effective approach to benign lesion at paraglottic space.
