眶上动脉跨区供血的反流轴型耳前岛状皮瓣修复眼睑皮肤组织缺损

目的探讨眶上动脉跨区供血的耳前岛状皮瓣修复眼睑皮肤缺损,并验证其是否为最佳的皮瓣供区.方法根据陈宗基关于动脉经吻合支跨区反流灌注供血的反流轴型皮瓣的理论与实践,设计以眶上动脉为蒂,经眶上动脉与颞浅动脉额支的吻合支跨区反流供血的耳前岛状皮瓣,经皮下隧道移转修复眼睑皮肤组织的缺损,1997～1999年共治疗7例,面积最大4.0cm×2.4cm,最小2.0cm×1.8cm.结果7例均全部成活,随访l～2年,效果良好.结论眶上动脉跨区供血的反流轴型耳前岛状皮瓣具有稳定、可靠的血供保障,耳前皮肤组织的质地、色泽都与眼睑极为相似,是修复眼睑组织缺损的理想皮瓣供区.

Eyelid reconstruction with a reversal flow axial preauricular island flap based on the supraorbital artery

OBJECTIVE: In order to find an ideal flap to reconstruct the eyelid defect, we have explored the possibilities to reconstruct eyelid with a reversal flow axial preauricular island flap based on the supraorbital artery. METHODS: According to Chen's theory on "reversal flow axial flap", we designed and applied the reversal flow axial preauricular island flap based on the supraorbital artery, which could nourish the flap by anastomotic branches between the supraorbital artery and the frontal branch of the superficial temporal artery. RESULTS: We have successfully reconstructed 7 cases of eyelid defect with this method since 1997. The size of the flaps ranged from 4.0 cm x 2.4 cm to 2.0 cm x 1.8 cm and good result were revealed with 1-2 years follow up. CONCLUSIONS: The flap has a stable and reliable blood supplying. It is an ideal flap to reconstruct the eyelid defect for texture and color similarity of the eyelid and preauricular skin.
