改良颞肌瓣纠正术后供区凹陷畸形的作用

目的探讨改良颞肌瓣纠正传统颞肌瓣术后供区凹陷畸形的作用。方法回顾分析15例上颌窦恶性肿瘤患者,采用改良颞肌瓣修复肿瘤切除后的创面。结果所有患者随访12~54个月,均未发生改良颞肌瓣坏死,1例术后放疗过程中出现腭部颞肌瓣缝合口处裂开,放疗结束3个月后自行愈合。改良颞肌瓣术后4~6周上皮化,功能重建效果良好,与传统颞肌瓣方法相比,未见供区产生凹陷畸形。结论改良颞肌瓣与传统颞肌瓣一样,可以用于上颌窦恶性肿瘤切除术后巨大创面的修复,且供区未见凹陷畸形,患者满意度高。

The Modified Temporalis Muscle Flap for Correcting Depressed Deformity of Donor Site after Surgery

Objective To evaluate the modified temporalis muscle flap （TMF） for correcting depressed deformity of donor site after surgery. Methods In this retrospective study, 15 patients with malignant maxillary tumor were involved. The modified temporalis muscle flap was used to repair the defect after tumor resection. Results All the patients were followed up for 12-54 months. All flaps were survived, except one case suffered from operative incision split and healed itself 3 months after radiotherapy. Epithelization of the fascia in oral cavity was completed in 4-6 weeks. Good functional reconstruction was achieved and no temporal deformity was observed. The cosmetic results were better compared with traditional temporalis muscle flap. Conclusion The modified TMF, the same as traditional temporalis muscle flap, can be served as the first-line reconstructive option for maxillary defects. And it can get better temporal cosmetic results with more satisfaction.
