A significant soft-tissue defect involving the helix of the external ear may present a difficult challenge to repair.
We describe our experience with the staged retroauricular to auricular pedicle flap for repair of soft-tissue defects with exposed cartilage of the helix of the ear.
The staged pedicle flap was used to repair 26 helical ear defects after excision of basal cell carcinoma (n = 16), squamous cell carcinoma (n = 3), and melanoma (n = 7).
Defect size ranged from 1 x 2 cm to 4 x 6 cm (average 2.4 x 3.3 cm). Defects involved the superior helix in 12 patients, mid helix in 11, and inferior helix in three. No cases of infection or flap necrosis occurred.
The staged retroauricular to auricular pedicle flap consistently provides a good to excellent functional and cosmetic outcome when performed on properly selected helical ear defects.
涉及耳廓螺旋部的显著软组织缺损修复可能是一项艰巨挑战。
我们描述了采用分期耳后至耳廓带蒂皮瓣修复伴有耳廓螺旋部软骨外露的软组织缺损的经验。
采用分期带蒂皮瓣修复26例耳廓螺旋部缺损，这些缺损是在切除基底细胞癌（n = 16）、鳞状细胞癌（n = 3）和黑色素瘤（n = 7）后出现的。
缺损大小范围为1×2厘米至4×6厘米（平均2.4×3.3厘米）。12例患者的缺损累及螺旋部上半部分，11例累及中部，3例累及下半部分。未发生感染或皮瓣坏死病例。
对于经过适当选择的耳廓螺旋部缺损，分期耳后至耳廓带蒂皮瓣始终能带来良好至极佳的功能和美容效果。
