股前外侧肌皮瓣修复恶性肿瘤切除术后上颌骨缺损

目的探讨股前外侧肌皮瓣修复颌面部组织缺损的临床应用效果。方法对6例上颌骨恶性肿瘤患者行上颌骨扩大根治术，上颌骨组织大面积缺损用股前外侧肌皮瓣修复，切取的肌皮瓣长9．0～11．0cm，宽4．0～6．0cm。结果1例皮瓣远端小部分坏死，其余5例皮瓣完全成活，外形恢复满意，下肢负重、行走不受影响。随访6～36个月，1例术后2年死于肿瘤肺转移，1例术后11个月复发，放射治疗后痊愈。结论股前外侧肌皮瓣成活率高、面积大、外形满意，可用于上颌骨恶性肿瘤扩大根治术后大面积组织缺损的修复。

Thigh anterolateral musculocutaneous flap for repairing of maxillary bone defect following malignant tumor ablation

Objective To investigate the clinical effect of the thigh anterolateral musculocutaneous flap for repairing tissue of maxillofacial region defcets. Methods Six patients of maxilla malignant tumors were treated with extensive radical resection of maxillary bone, The large maxillary bone tissue defects were reconstructed with thigh anterolateral musculocutaneous flap. The musculoeutaneous flaps were 9 to 11 cm in length and 4 to 6 cm in width. Results Five cases of musculocutaneous flap survived completely with satisfactory shape except that one was necrosis in distal end subsection, the weight loading of lower limb and walking were not affected. After 2 years, one case was dead with tumor pulmonary metastasis, one case recrudesced after surgery and was cured by radiation therapy after 11 months, followed up 6 to 36 months. Conclusions The survival rate of thigh anterolateral musculocutaneous flap was satisfactory and areas were large enough,the reconstructed maxillofacial tissue were found to have good appearance. It＇s an ideal choice for repairing oversized defects after extensive radical resection of maxilla malignant tumors.
