目的探讨本研究设计的扩大耳后带蒂肌骨膜瓣-耳道皮瓣复合瓣,结合骨粉乳突术腔填塞术,应用于开放式改良乳突根治术治疗胆脂瘤型中耳炎的临床疗效和意义。方法 2003年4月至2005年3月间胆脂瘤中耳乳突炎患者71例(71耳)施行在开放式改良乳突根治术基础上,应用扩大耳后带蒂肌骨膜瓣-外耳道皮瓣复合瓣,结合骨粉乳突术腔填塞术,同期行鼓室成形术。结果术后随访≥2年。手术后术腔完全上皮化时间为3周～1.5个月,平均29 d。全部乳突术腔获干耳。结论扩大耳后带蒂肌骨膜瓣-耳道皮瓣复合瓣,结合骨粉行乳突术腔填塞术,应用于开放式改良乳突根治术,治疗胆脂瘤型中耳炎具有以下优点:乳突术腔愈合时间短,上皮修复覆盖好;可避免乳突术腔植皮;术后干耳率高,基本无需术后乳突术腔清理。
Objective To explore the clinical effect of expanding the posterior pedicled pedicled periosteal flap - the flap of the auditory canal skin flap combined with the infusion of bone meal mastoid technique in the open modified radical mastoidectomy for the treatment of cholesteatoma otitis media significance. Methods From April 2003 to March 2005, 71 patients (71 ears) with cholesteatoma otitis media were treated with open modified radical mastoidectomy. Flap compound flap, combined with bone meal mastoid cavity filling operation, simultaneous tympanoplasty. Results Postoperative follow-up ≥ 2 years. Surgical cavity complete epithelialization time of 3 weeks to 1.5 months, an average of 29 d. All mastoid cavity dry ear. Conclusions The expansion of the posterior pedicled pedicled periosteal flap - the flap of the ear canal combined with the transplastomy of bone meal in the treatment of cholesteatoma otitis media has the following advantages: mastoid surgery Cavity healing time is short, covering epithelial repair is good; can avoid mastoid cavity skin graft; postoperative dry ear rate, the basic postoperative mastoid cavity cleaning.
