应用显微外科技术改良颈阔肌皮瓣的临床应用

目的探讨应用显微外科技术改进颈阔肌皮瓣以修复口腔颌面部缺损的可行性及应用价值。方法以携带肌袖血管蒂的改良颈阔肌皮瓣一期修复口颊部缺损12例，软腭缺损3例，口底缺损1例；同期行颈淋巴结清扫术。结果15例肌皮瓣全部成活，1例肌皮瓣因静脉回流障碍皮瓣远端部分皮肤坏死。修复区手术组织量适中。形态良好，颈部瘢痕不明显。结论应用显微外科技术改良颈阔肌皮瓣不影响血供，肌皮瓣自由度明显改善，适于修复口腔颌面部手术。

Clinical application of platysma flap with microsurgical procedure

Objective To analyze the value and feasibility of platysma flap transfers for oral and maxillofacial reconstruction. Methods The microsurgery procedure was used in the treatment of 16 patients with oral and maxillofacial defect after surgery. Results Fifteen patients flaps were survived. 1 patients flap was necrosis because of blood supply deficiency. Conclusion This is a good approach to the reconstruction of oral and maxillofacial defect by using platysma flap with microsurgery procedure.
