目的:研究颊脂垫瓣在口腔黏膜下纤维性变(OSF)切除后组织缺损修复中的应用。方法:10例伴重度张口受限的OSF患者,应用颊脂垫瓣修复切除后遗留的组织缺损,观察颊脂垫瓣的愈合过程及修复效果。结果:术后9例患者张口度均大于3cm,颊脂垫瓣愈合良好,术后1周颊脂垫瓣明显水肿,组织瓣表面有薄层伪膜覆盖,1周后伪膜逐渐消失,2周后伪膜完全消失,2～3周后水肿明显消退,颊脂垫表面逐渐上皮化,6～8周再生的黏膜变得光滑,呈粉红色,类似于正常口腔黏膜。结论:颊脂垫瓣为修复OSF术后缺损提供了一种良好的手术方式,有利于改善张口受限症状。
Objective: To study the application of buccal fat pad in the repair of tissue defects after oral submucosal fibrosis (OSF) resection. Methods: Ten patients with severe OSF with limited mouth opening were treated with buccal fat pad to repair the tissue defect left after resection. The healing process and repair effect of buccal fat pad flap were observed. Results: The mouth opening of 9 patients was more than 3cm after operation. The buccal fat pad flap healed well. The buccal fat pad flap was edematous after 1 week. The surface of the flap was covered with thin pseudomembrane. The pseudomembranous gradually disappeared after 1 week. Pseudomembranous disappeared completely after 2 weeks. Edema disappeared obviously after 2 to 3 weeks. The surface of buccal fat pad gradually epithelized. The mucosa regenerated from 6 to 8 weeks became smooth and pink, similar to normal oral mucosa. Conclusion: Buccal fat pad flap provides a good surgical method for the repair of postoperative OSF defects, which will help to improve the limited symptoms of mouth opening.
