应用颞浅动脉额支岛状皮瓣修复下睑基底细胞癌切除后创面

目的 探讨下睑基底细胞癌的治疗方法。方法 术前用超声多普勒测定并标记颞浅动脉及其额支的走行方向。术中距病损边缘0．5～1.0cm切除病变组织，并送冰冻切片检查，以确定病变的性质及是否切除彻底。据术前标记设计额部皮瓣，皮瓣应大于缺损0．5cm，蒂长大于蒂到缺损区1．0～1．5cm，宽约3cm。累及眼睑全层的缺损，将结膜游离后上拉与皮瓣缝合，或将皮瓣设计足够大，将皮瓣边缘修成全厚皮，翻转后与结膜缝合。供区创面较大，可考虑皮片移植修复。结果 本组5例，均行额部岛状皮瓣修复，术后无下睑缺损及外翻。结论 应用颞浅动脉额支岛状皮瓣修复下睑基底细胞癌切除后创面，效果良好。

Application of superficial temporal artery frontal branch island flap for repair of defect secondary to lower eyelid basal cell carcinoma

Objective To investigate the repair of defect secondary to removal of lower eyelid basal cell carcinoma. Methods The superficial temporal artery and its frontal branch were detected and labeled by ultrasound Doppler blood velocity detector. During surgery, the lesion was excised with 0.5-1. 5 cm margin. Frozen sections were made to clarify the diagnosis. The frontal flap was designed according to the preoperative labeling, and the flap was 0.5 cm larger than the defect, the pedicle was 1.0 - 1. 5 cm longer than the distance between pedicle and defect, and the width of pedicle should be 3 cm. In the case of lesion affected the full thickness of lower eyelid, conjunctival flap was sutured with the flap. Skin graft was applied when the defect was big. Results A series of five patients was treated by this method. The defects were repaired successfully. There was no secondary defect or ectropion after surgery. Conclusion The superficial temporal artery frontal branch island flap is a satisfactory therapeutic method for the repair of defect secondary to the removal of lower eyelid basal cell carcinoma.
