摘要/Abstract

摘要：

　目的　评价耳后筋膜的组织形态学特征，并对其进行几何学设计改良，以改善颅耳沟重建术后颅耳沟外观，并

减少术后局部并发症的发生。方法　对16例患者进行耳后筋膜厚度的超声测量，通过几何学设计得到耳后上筋膜瓣，

并将该方法用于 125例颅耳沟重建术。结果　耳后筋膜由上至下厚度逐渐增加。耳后上筋膜瓣较传统的耳后筋膜瓣

在手术操作上更简单，术后的颅耳沟形态更自然，耳后局部皮肤坏死和瘢痕增生减少。结论　最大限度利用接近顶侧

耳后筋膜组织设计的改良耳后上筋膜瓣，在手术效果及减少术后并发症方面均优于传统耳后筋膜瓣。

Abstract:

Objective To evaluate histomorphometric features of the retroauricular fascia and geometrically re-design a

novel fascia flap to improve the posterior appearance of reconstructed ear and reduce complications after ear elevation.

Methods The thickness of retroauricular fascia was measured by ultrasound in 16 patients. The posterosuperior auricular

fascia flap was designed by geometry. And the method was applied in 125 cases of ear elevation. Results The fascia layer

thickness increased from superior to inferior. By using posterosuperior auricular fascia flap， the surgical procedure became

easier， the posterior appearance of reconstructed ear was more natural after operation， and the incidence of postauricular

hypertrophic scarring and partial skin graft necrosis also decreased. Conclusion The modified posterosuperior auricular

fascia flap designed to maximize the use of the posterior fascia tissue of the parietal side is superior to the traditional

retroauricular fascia flap in terms of surgical effect and reduction of postoperative complications.
