目的探讨全耳再造第一期手术后耳区的负压引流情况及再造耳形态的塑形结果。方法采用20mL针筒负压抽吸引流,观察50例全耳再造第一期手术病人,分别记录耳舟与耳甲腔处留置的引流管的术后前3天每日引流量,观察耳区皮瓣情况及再造耳形态的变化。结果术后前3天耳舟处平均引流量分别为12.10mL、3.80mL、1.61mL,耳甲腔处平均引流量分别为7.54mL、2.37mL、0.96mL,第3天引流量极少。其中2例病人术后2h内出现血肿,给予立即清除;3例术后引流量较多(大于50mL),给予增加负压和抽吸频率,其再造耳形态近期较臃肿。结论该引流方法管理方便,一般3天即可拔去引流管,术区及时引流与负压调整是影响再造耳形态和皮瓣血运的重要因素。

Objective To investigate the effects of negative-suction drainage for ear reconstruction and its relationship with constructed ear shape. Methods A continuous negative suction drain system with 20 mL syringe was used in 50 cases, which were treated by one stage operation of ear reconstruction. During the first three days after operation, the amount of fluid from the scapha and the concha were recorded separately. The ear shape and the circulation of the flap were observed simultaneously. Results During the ...
