眶区组织缺损修复中眶周血的应用

目的 探讨眶周血供在眶区组织缺损修复中的应用。 方法 选取2013年12月至2016年12月确诊治疗的眶区组织缺损患者100例,依据治疗方法分为A组和B组,每组50例,A组给予耳前反流轴型皮瓣、额部岛状皮瓣、耳后反流轴型皮瓣、鼻唇沟皮瓣等眶周皮瓣旋转修复术治疗;B组在此基础上行皮下蒂皮瓣处理。 结果 B组治疗优良率明显高于A组,B组愈合时间、并发症发生率低于A组,差异有统计学意义(P<0.05);两组术后血流速度(BFV)、血流灌注量相对值(BPR)水平均高于术前,B组术后BFV、BPR水平高于A组,差异有统计学意义(P<0.05)。 结论 眶周皮瓣血供丰富、可塑性好、色泽质地与受区相近,适用于眶区组织缺损修复,且联合皮下蒂皮瓣处理时,具有更为良好的疗效及安全性。

Application of periorbital blood supply for repairing tissue defects in the orbital region

Objective The aim of this study was to investigate the application of periorbital blood supply for repairing tissue defects in the regiones orbitalis. Methods A total of 100 patients with tissue defects in the regiones orbitalis were enrolled from December 2013 to December 2016 in the hospital. According to the treatment protocol, the patients were divided into group A and group B, with 50 patients in each group. Group A was treated with periorbital flap and rotation prosthesis, such as ear before reflux axial flap, forehead island flap, and reflux after ear type axial flap, and nasolabial sulcus flap. Group B was administered subcutaneous flap treatment. Results Treatment efficiency was significantly higher in group B than in group A, but the healing time and complication rate were significantly lower in group B than in group A(P<0.05). The postoperative blood flow velocity(BFV)and blood flow rate(BPR)were significantly higher than the preoperative values. In both group A and group B, and the postoperative BFV and BPR were significantly higher in group B than in group A(P<0.05). Conclusion The periorbital flap has advantageous characteristics, such as rich blood supply, good plasticity, and similarity of materials and colors to those of surrounding regions. Therefore, the periorbital flap is suitable for repairing tissue defects in in the regiones orbitalis, and combined treatment with hypodermic and periorbital flap shows a better therapeutic effect with improved safety.
