Innovated surgery incision for patients of congenital malformation of the middle and outer ear with infection (CMMOEI)

Abstract

Background

It is the challenging clinical issue of combining debridement of infected lesions and retaining the blood skin flap for auricle reconstruction in patients of Congenital Malformation of the Middle and Outer Ear with Infection (CMMOEI).

Aims/Objectives

To innovate and introduce an surgery incision to solve the challenging clinical issue of a combined debridement of infection yet retaining a well vascularized skin flap for auricle reconstruction in patients with CMMOEI.

Material and Methods

A combined innovated incision of ear sulcus and prefabricated earlobe was used for 23 cases (23 ears) with CMMOEI, The success in the management of the encountered infections, and the short and moderate-term outcome of the innovated incision to preserve a well-vascularized skin flap for subsequent auricle reconstruction were reviewed. The 23 cases include 10 males and 13 females, aged 4-14 years (mean 8.4 years), 7 left ears and 16 right ears. 14 ears stenosis and 9 ears atresia of the outer ear canals.

Results

In all 23 cases, the infections were successfully cleared without recurrence or complication with 2-year follow-up. The local skin flap and its blood supply were well preserved for subsequent auricle reconstruction.

Conclusions and Significance

The new incision can facilitate clearance of infection in CMOMEI patients, and preserve the retroauricular tissues for subsequent harvesting of a well-vascularized skin flap for subsequent auricle reconstruction.

Chinese Abstract

背景: 为先天性中耳和外耳畸形并具感染(CMMOEI)的患者的耳廓重建, 感染病灶清创和保留血皮瓣相结合是一个具有挑战性的临床问题。

目的: 开创并引入手术切口来解决这样一个具有挑战性的临床问题, 即, 为CMMOEI 患者的耳廓重建, 联合清创感染同时保留血管良好的皮瓣。

材料与方法: 耳沟创新切口与预制耳垂联合用于 23 例(23只耳)CMMOEI患者。我们对所发生的感染的成功处理, 以及创新切口来保留血管良好的皮瓣用于随后耳廓重建的短期和中期结果, 进行了回顾。 23例病例中, 男性10人, 女性13人, 年龄4至14岁(平均8.4岁), 左耳7只, 右耳16只, 14只耳狭窄, 9耳外耳道闭锁。

结果: 23例感染均被成功清除, 无复发或并发症, 并有两年随访。 局部皮瓣及其血供保存完好, 以便的后续耳廓重建。

结论及意义: 新切口有利于CMOMEI患者感染的清除和保留耳后组织, 以便随后采集血管丰富的皮瓣用于耳廓重建。
