摘　　要：目的探讨耳甲腔转移皮瓣联合耳甲腔成形术扩大外耳道口的临床价值。方法选择接受治疗的40例外耳道疾病患者,采用随机数字表法患者分为2组,每组20例。单纯组患者采用耳甲腔成形术治疗;联合组患者采用耳甲腔转移皮瓣联合耳甲腔成形术治疗。比较2组患者的外耳道口扩大情况、耳甲腔成形时间、干耳时间情况,比较2组患者随访中术腔结痂情况、并发症发生情况,分析2组患者手术前后听力(气道听阈、骨气导差)变化情况。结果 2组患者外耳道口扩大情况均较术前扩大。单纯组外耳道口扩大形状接近三角形,而联合组外耳道口扩大形状类似圆形,联合组扩大效果更佳(P <0. 05)。联合组耳甲腔成形时间、干耳时间均明显短于单纯组,差异有统计学意义(P <0. 05)。随访发现,联合组术腔结痂率为15. 00%、并发症发生率为10. 00%,均明显低于单纯组的45. 00%和40. 00%,差异有统计学意义(P <0. 05)。术前,2组患者的听力情况差异无统计学意义(P> 0. 05);术后,联合组患者的气道听阈、骨气导差较手术前均明显降低,且降低幅度大于单纯组,差异有统计学意义(P <0. 05)。结论耳甲腔转移皮瓣联合耳甲腔成形术应用于扩大外耳道口的临床价值更高,可改善患者的听力情况,值得临床应用。Objective To investigate the clinical value of cavity of auricular concha local flap grafting combined with cavity of auricular concha plasty to enlarge the outer ear canal.Methods A total of 40 patients with external auditory canal disease who were treated in our hospital from September 2016 to September 2017 were enrolled in the study.According to random number table method,these patients were divided into simple surgery group(n=20)and combination surgery group(n=20).The patients in simple surgery group were treated by cavity of auricular concha plasty,however,the patients in combination surgery group were treated by cavity of auricular concha local flap grafting combined with cavity of auricular concha plasty.After operation the enlargement status of external auditory canalouter ear,forming time of cavity of auricular concha and dry ear time were observed and compared between the two groups.Moreover the surface deposition status,incidence of complications during follow up were compared between two groups.In addition the changes of audition including airway auditory threshold,bone air conduction difference before and after operation were observed and compared between the two groups.Results After operation the expansion of the outer ear canal in both groups was larger than that before surgery.The extension of the outer ear canal in simple surgery group was similar to triangle,while the extension of the outer ear canal in combination surgery group was similar to round,and the expanding effects in combination surgery group were superior to those in simple surgery group(P<0.05).Moreover the forming time of cavity of auricular concha and dry ear time in combination surgery group were significantly shorter than those in simple surgery group(P<0.05).The follow-up results showed that surface deposition rate in combination surgery group was 15.00%,and the incidence rate of complications was 10.00%,which were significantly lower than those in simple surgery group(P<0.05).Before the operation,there was no significant diff
