负压引流装置在小耳畸形患者皮肤扩张法耳郭再造二期手术中的应用

A negative pressure drainage device for dermal dilatation of microtia in the second phase of auricular reconstruction surgery

目的探讨一种负压引流装置在皮肤扩张法耳郭再造二期手术中的临床应用效果。方法收集420例需要外耳再造的小耳畸形患者,应用皮肤扩张器植入法加自体肋软骨移植行耳郭再造术。按照术后引流方式随机分为两组:实验组(290例)采用专用负压引流装置;对照组(130例)常规放置一根负压引流管。比较两组患者皮下血肿的发生率并作统计学分析。结果与对照组相比,应用专用负压引流装置组皮下血肿发生率较低,差异有统计学意义(P<0.05)。结论在小耳畸形皮肤扩张法耳郭再造二期手术中,应用此负压引流装置可以有效防止术腔血肿,值得临床推广应用。

Objective The objective of this study was to introduce a negative pressure drainage device for dermal dilatation of microtia during the second phase of auricular reconstruction surgery.Methods A total of 420 patients with microtia who required skin expander implantation and cartilage framework grafts for auricular reconstruction were included in the study and randomly divided into two groups according to postoperative drainage.The study group used a special negative pressure drainage device(n=290)and a negative pressure drainage tube was placed routinely in the control group(n=130).We statistically compared the rates of subcutaneous hematoma formation between the two groups.Results In the study group,subcutaneous hematomas were less frequent than in the control group(P<0.05).Conclusions The special negative pressure drainage device effectively prevented subcutaneous hematomas during dermal dilatation of microtia in the second phase of auricular reconstruction surgery.This device is widely used clinically.
