耳道扩大联合耳甲成形治疗Ⅱ～Ⅲ期外耳道胆脂瘤35例的临床体会

Therapeutic effect of ear canal dilatation combined with cavity formation of auricular concha in 35 cases with stage Ⅱ ～ Ⅲ external auditory canal cholesteatoma

目的探讨耳道扩大联合耳甲成形治疗Ⅱ～Ⅲ期外耳道胆脂瘤(EACC)的临床效果。方法回顾分析35例Ⅱ～Ⅲ期EACC患者的临床资料。结果全部患者均一次完成手术,术后病理均确诊为胆脂瘤。术后外耳道通畅,耳闷、耳痛、耳流脓症状消失。2周后干耳,术腔均在3个月内完全上皮化。术后随访3～24个月,未见胆脂瘤复发。听力结果显示患者术后言语频率气骨导差较术前明显减小,差异有统计学意义(P <0. 05)。结论Ⅱ～Ⅲ期EACC行耳道扩大联合耳甲成形具有临床应用优势。

Objective To explore the clinical effect of ear canal dilatation combined with cavity formation of auricular concha in the treatment of stage Ⅱ ～ Ⅲ external auditory canal cholesteatoma( EACC). Methods Thirtyfive cases of stage Ⅱ ～ Ⅲ EACC were analyzed retrospectively. Results All the 35 cases underwent surgery at one time. Postoperative pathology was done to confirm as cholesteatoma. After the operation,the external ear canal was unobstructed,and the symptoms of ear tightness,ear pain and ear pus all disappeared. The external auditory canal got dry within two weeks. The surgical cavity was completely epithelized within three months,and no recurrence was observed after 3 ～ 24 months. The postoperative speech frequency air-bone gap decreased significantly( P < 0. 05).Conclusions Ear canal dilatation combined with cavity formation of auricular concha has more clinical advantages in the treatment of stage Ⅱ ～ Ⅲ EACC.
