摘要:: [摘要]目的：探讨利用“旗形”胸脐皮瓣结合自体肋软骨支架行阴茎再造的临床效果。方法：以腹壁下动脉为蒂设计脐旁皮
瓣，皮瓣形态呈旗状，“旗杆”部为皮瓣血管蒂，“旗面”部用于阴茎成形及尿道成形。以“旗杆”为轴旋转180°转移至
会阴部，将皮瓣翻转卷成管状形成尿道及阴茎体，并与会阴部尿道口吻合。手术同期切取自体肋软骨，雕刻为支撑材料置
入阴茎体。术后半年可行二期手术修整阴茎形态，包括皮瓣去脂修薄、瘢痕切除等。结果：2010年8月-2016年8月供实施8
例，术后皮瓣血运均良好，皮瓣供区均可于术中直接缝合关闭创面，伤口一期愈合。术后随访5～14个月，其中2例患者阴茎
臃肿，于阴茎再造术后1年行皮瓣去脂修薄改善阴茎外形，满足性生活；2例术后3个月因尿瘘再次行手术修补；其余4例患者
再造阴茎外观及功能均良好。所有患者均未见软骨外露，除脐部位置稍向皮瓣供区侧偏移，腹壁外形轮廓基本正常。结论：
“旗形”胸脐皮瓣阴茎再造设计简单，术后效果较为理想，避免了传统胸脐皮瓣阴茎再造需要植皮覆盖创面的问题，减轻了
腹壁继发畸形的发生，是一种可供选择及推广的阴茎再造术式。

Abstract:: Abstract: Objective To investigate the application of flag-shaped paraumbilical flap combined with autologous costal
cartilage framework implantation in penile reconstruction. Methods Flag-shaped paraumbilical flap was designed for penile
reconstruction and costal cartilage framework implantation. The flag-shaped flap based on inferior epigastric artery was
designed for the penile and urethra reconstruction. Autologous costal cartilage was harvested as well, applied as supportive
structure. Second stage of surgery for appearance improving was performed when necessary. Results Eight patients were
underwent there kind flaps for penile reconstruction from August 2010 to August 2016. All the flaps remained 100% viable
postoperatively. Due to the appropriate flap planning, the donor site can be sutured directly , skin graft was unnecessary as well.
Follow-up ranged from 5 months to 14 months. There were 2 cases of flap defat for better appearance and 2 cases of urethral
fistula, while none of cartilage implant extrusion happened. For other 4 patient, both function and appearance are satisfying.
The malformation of the donor site was inconspicuous, a little bit of umbilicus shift was acceptable. Conclusion Flag-shaped
paraumbilical flap for penile reconstruction was a modification based on traditional paraumbilical flap planning, skin graft for
donor site coverage was unnecessary and the donor site deformity was minimal.
