应用游离股前外侧脂肪筋膜瓣矫治半侧颜面萎缩的临床研究

目的探讨应用股前外侧脂肪筋膜瓣游离移植矫治半侧颜面萎缩的临床效果。方法1997年1月～2006年5月，应用以吻合血管的股前外侧脂肪筋膜瓣游离移植，部分加以Medpor植人及二期手术修整，矫治半侧颜面萎缩患者35例。男11例，女24例；年龄15～47岁。左侧12例，右侧23例。病程4～28年。患者半侧颜面畸形较严重，面颊部凹陷明显。X线片及三维CT重建检查见28例患侧骨骼发育不良。切取脂肪筋膜瓣范围8cm×7cm～20cm×11cm。供区直接缝合。结果术后患者伤口均I期愈合，脂肪筋膜瓣全部成活，供区切口愈合良好，无脂肪液化。35例均获随访6个月～8年。面部轮廓形态满意，双侧基本对称，供区无明显功能障碍。结论吻合血管的股前外侧脂肪筋膜瓣可提供充足的组织量，成活率高，供区隐蔽，不牺牲重要血管，辅以相应的非生物材料及治疗手段，可使半侧颜面萎缩得到满意矫治。

CLINICAL STUDY ON CORRECTION OF HEMIFACIAL ATROPHY WITH FREE ANTEROLATERAL THIGH ADIPOFASCIAL FLAP

OBJECTIVE: To investigate the effect of free anterolateral thigh adipofascial flap in correcting the hemifacial atrophy. METHODS: From January 1997 to May 2006, 35 patients suffering from hemifacial atrophy were corrected with microvascular anastomotic free anterolateral thigh adipofascial flap and other additional measures according to the symptoms of the deformities. There were 11 males and 24 females, aging 15-47 years. The locations were left in 12 cases and right in 23 cases. The course of disease was 4 to 28 years. Their hemifacial deformities were fairly severity. Their cheeks were depressed obviously. The X-ray films and three-dimensinal CT showed the 28 patients' skeletons were dysplasia. The size of adipofascial flap ranged from 8 cm x 7 cm to 20 cm x 11 cm. Donor sites were sutured directly. RESULTS: Recipient site wound of all patients healed by first intention. All adipofascial flaps survived. The donor sites healed well and no adiponecrosis occurred. Thirty-five cases were followed up for 6 months to 8 years. The faces of all patients were symmetry, and the satisfactory results were obtained. There were no donor site dysfunction. CONCLUSION: The anterolateral thigh adipofascial flap provides adequate tissue, easy-to-survive, no important artery sacrificed and the donor scar is more easily hidden. Combining with other auxiliary methods, it can be successfully used to correct the deformity of hemifacial atrophy.
