摘要
目的:本研究制备血管化真皮脂肪瓣,采用原位皮肤的半厚皮片来关闭前臂供区,评估供区术后的美学及功能.方法:2020年7月-2023年6月行血管化前臂真皮脂肪瓣修复13例口腔颌面部软组织缺损,其中男8例,女5例;年龄42～71岁.切取皮瓣面积最大8 cm×7cm,面积最小7 cm×5 cm,供区缺损采用原位皮肤的半厚皮片关闭.术后6个月,对前臂供区的颜色匹配程度、术区瘢痕、手腕活动和手部的感觉进行评估.结果:术后15例完全存活,所有患者术后供区均Ⅰ期愈合.术后随访6个月,前臂供区颜色匹配,无运动感觉功能障碍.结论:血管化前臂真皮脂肪瓣供区可以直接关闭,降低供区延期愈合的发生率,可以作为传统前臂皮瓣的替代方案,是口腔颌面部软组织缺损一种比较可靠的修复方式.
Abstract
Objective:This study prepared vascularized dermal fat flaps and introduced a local split-thickness skin graft from an in situ cutaneous area cutaneous area to manage forearm flap donor sites and evaluated the es-thetic and functional outcomes post-operatively.From July 2020 to June 2023,13 patients with soft tissue defects in Oral and Maxillary Area were repaired with tvascular forearm dermal fat flap.There were 8 males and 5 fe-males,aged from 42-71 years.The flaps ranged from 8 cm×7 cm to 7 cm×5 cm in size.The donor site defects were covered by local split-thickness skin graft from the in situ skins.The color matching degree,surgical scars,ranges of wrist movement and hand sensations in donor forearms were assessed at 6 months after surgery.Re-sults:The tvascular forearm dermal fat flaps for 15 cases all survived.All the local split-thickness skin grafts transplanted with this technique showed primary healing.The follow-up period for 6 months,Donor site exhibited suitabler color matching and there was not severe complications.Conclusion:The vascularized dermal fat flap pro-vides an alternative to conventional forearm flap harvest,which enables primary donor site closure with reduced rates of delayed donor site healing.The vascularized dermal fat flap is a relatively reliable repair method for soft defects in Oral and Maxillary Area.
