Objective:To investigate the clinical diagnosis and treatment of idiopathic subglottic stenosis.Methods:From May 2012 to January 2014,four patients with idiopathic subglottic stenosis admitted in the Department of Otolaryngology,the Affiliated Drum Tower Hospital of Nanjing University Medical School,Nanjing,Jiangsu,China were selected for review.Results:All the four patients with idiopathic subglottic stenosis were resolved after the resection of the pathological tissues and subsequent hormone treatment.Conclusions:The confirmed diagnosis of idiopathic subglottic stenosis mainly relied on the medical history and pathological examination.Favorable treatment effects might be obtained by combining surgical resection and hormone treatment.%目的:探讨特发性声门下型喉狭窄的发病机制及临床诊治方法.方法:对我科2012年5月-2014年1月收治的4例特发性声门下型喉狭窄患者的临床资料进行回顾性研究,在基本相同的手术方式、不同的术后用药下进行长期随访,电子喉镜下观察患者术前、后及随访2年的病灶区情况并进行相关统计学分析.结果:4例特发性声门下型喉狭窄患者多因呼吸困难就诊,均采用气管切开术及支撑喉镜下热器械切除病变,旷置创面的手术方式,术后短期内气道狭窄均得到解决、呼吸困难症状均得到缓解;配合小剂量激素中长期治疗效果尚可,患者声门下病灶无明显复发,气道症状能得到控制,其中2例患者治愈,1例患者因拒绝激素治疗术后未予激素治疗中期观察有效,1例患者术中术后未予激素治疗,术后短期复发,后经激素治疗治愈.结论:特发性声门下型喉狭窄是后天性声门下狭窄的非瘢痕性的特殊类型,为独特的喉狭窄炎症性疾病,病因不明或为某些因素引起了非特异的增生性炎症,表现为炎性细胞的浸润及淋巴组织增生.治疗上,手术能明显缓解其症状,但单纯手术治疗中长期效果不佳,极易复发;配合中长期小剂量激素治疗对病灶控制有重要的作用.
