背景:由于与张力闭合相关的缺血和随后的坏死,高张力解剖区域的手术缺损的重建具有挑战性。对能够闭合这些缺损并施加较小张力的新型皮瓣的研究将是皮肤病外科的巨大进步。
方法:我们进行了多中心,回顾性研究使用2个新的皮瓣-主教和sigma-修复高张力区域的手术缺陷,如头皮,下肢,还有鼻金字塔.9名患者使用了主教皮瓣,其中5人在鼻金字塔中表现出病变,2在腿上,另外2在头皮上。6例患者使用sigma皮瓣,其中5例表现为头皮病变,1例表现为腿部病变。
结果:由于感染,所有15例患者均获得了良好的结果,开裂,或坏死。
结论:主教和sigma皮瓣都是修复头皮等高张力区域手术缺损的良好替代方法,下肢,或者鼻金字塔.
BACKGROUND: The reconstruction of surgical defects in high-tension anatomical regions is challenging due to the ischemia and subsequent necrosis associated with tension closure. Research on new flaps capable of closing these defects exerting less tension would be a tremendous advancement in dermatological surgery.
METHODS: We conducted a multicenter, retrospective study that used 2 new flaps-the bishop and the sigma ones-to repair surgical defects in high-tension regions such as the scalp, lower extremities, and the nasal pyramid. The bishop flap was used in 9 patients, 5 of whom exhibited their lesion in the nasal pyramid, 2 in the legs and another 2 in the scalp. The sigma flap was used in 6 patients, 5 of whom exhibited scalp lesions and 1 leg lesion.
RESULTS: Uneventful and excellent results were obtained in all 15 patients due to infection, dehiscence, or necrosis.
CONCLUSIONS: Both the bishop and the sigma flaps are a good alternative to repair surgical defects in high-tension regions such as the scalp, lower extremities, or the nasal pyramid.
