应用阴囊肉膜平滑肌肌皮瓣修复阴茎延长术中的阴茎创面

目的 提供理想的阴茎延长术中阴茎创面的修复组织。方法 在阴茎1阴阜区皮肤交界处切开、切断阴茎浅悬韧带和部分阴茎深悬韧带行阴茎延长术后，应用以阴囊前动、静脉为血管蒂的阴囊膜平滑肌肌皮瓣（下简称阴囊皮瓣）转移修复在阴茎根部所形成的创面。结果 1996年以来共应用于16例患者，阴茎平均延长4－4．5cm，阴囊皮瓣全部成活，阴茎形态满意，阴囊无明显变形。结论 阴囊皮瓣血运丰富，薄而无皮下脂肪，有伸缩性，是阴茎延长手术中阴茎皮肤缺损较好的修复方法之一。

Repair of penile wounds in penis lengthening with the scrot al dartos musculocutaneous flaps

OBJECTIVE: To provide ideal materials for repair of penile wounds in penis lengthening. METHODS: A skin incision was made between the penis and mons pubis. Penis lengthening was performed by complete releasing of the superficial suspensory ligament and partial releasing of the deep suspensory ligament of the penis. Resurfacing of the defects at the penile base was accomplished by transferring a scrotal dartos musculocutaneous flap pedicled on the anterior scrotal vessels. RESULTS: 16 patients with short penis were treated with the method. All scrotal dartos musculocutaneous flaps survived and 4-4.5 cm extra length of the penile shaft was achieved. Appearance and function of the penis were improved. CONCLUSIONS: The scrotal dartos musculocutaneous flap is one of the best materials to repair the penile skin defects in penile lengthening operation. The advantages of the flap are: 1. good blood supply; 2. thin and lacking of subcutaneous fat; 3. extensibility with the scrotal dartos muscle.
