摘要目的 探讨应用前臂外侧皮神经营养血管逆行蒂岛状皮瓣修复手背软组织缺损的临床效果.方法 11例手背软组织缺损患者,最小缺损面积为3.0 cm×2.5 cm,最大为6.5 cm×4.0cm,采用前臂外侧皮神经营养血管逆行蒂岛状皮瓣修复,皮瓣切取面积为3.5 cm×3.0 cm～7.0 cm×4.0 cm.结果 术后11例皮瓣全部成活,随访2个月至2年,皮瓣质地弹性良好,手外形与功能改善满意,皮瓣浅感觉存在;前臂供区直接缝合7例,中厚植皮4例,外观满意.结论 前臂外侧皮神经营养血管逆行蒂岛状皮瓣是修复手背软组织缺损的较理想术式.

abstractsObjective To report the therapeutic effect of retrograde island neurocutaneous flap pedicled with lateral antebrachial cutaneous nerve for the treatment of soft tissue defect at the dorsum of hand. Methods 11 cases with soft tissue defects at the dorsum of hands were treated. The size of soft tissue defects ranged from 3.0 cm × 2.5 cm to 6. 5 cm × 4.0 cm. The size of the flaps ranged from 3.5 cm × 3.0 cm to 7.0 cm × 4.0 cm. Results All the 11 flaps survived. The follow-up period was 2 months to 2 years. The texture and elasticity of the flaps were good. The appearance and function of the hands were satisfactory. The superficial sense was recovered. The wounds at the donor site of forearms were closed primarily in 7 cases, or covered by split-thickness skin grafts in other 4 cases. The appearance of the donor site was satisfactory too. Conclusions The retrograde island neurovascular flap pedicled with lateral antebrachial cutaneous nerve is an optimal method for soft tissue defects at the dorsum of hand.
