为探讨游离股后内侧皮瓣在口腔颌面部缺损修复重建中的应用，本研究纳入2019年1月至 2020年1月就诊于郑州大学第一附属医院口腔颌面外科的口腔癌患者23例，男性13例，女性10例，年龄（54.5±9.7）岁（33~72岁）。23例患者在口腔癌切除同期均采用股后内侧皮瓣修复口腔颌面缺损。记录皮瓣供区穿支血管数目和类型，切取皮瓣大小、血管蒂长度和动静脉直径，皮瓣临床成活及供区并发症情况，并采用视觉模拟评分量表（visual analogue scale，VAS）评估患者对供区瘢痕隐蔽性的满意度。23例患者股后内侧供区均存在可利用的穿支血管，穿支血管数量为2支（1~4支），血管类型均为肌皮穿支。皮瓣血管蒂长度为（9.8±1.5）cm（7.3~13.4 cm），动脉直径为2.0 mm（1.5~2.5 mm），伴行较粗静脉直径为2.0 mm（1.5~3.0 mm）。切取皮瓣大小8 cm×6 cm~12 cm×8 cm，供区创面均直接拉拢缝合。23例股后内侧皮瓣临床全部成活。所有患者均未发生供区切口感染或肌力下降，仅1例患者术后14 d发生供区切口部分裂开。所有患者对供区瘢痕隐蔽性的满意度VAS评分均大于8。游离股后内侧皮瓣穿支血管较恒定，临床成功率高，供区瘢痕隐蔽，是口腔颌面缺损软组织修复重建的一种较好选择。“,”To explore the feasibility of using the posteromedial thigh flap as an alternative source for oral and maxillofacial reconstruction. During January 2019 to January 2020, twenty-three patients underwent oral and maxillofacial tumor ablation and defect reconstruction with 23 posteromedial thigh flaps were enrolled in the Department of Oral and Maxillofacial Surgery, The First Affiliated Hospital of Zhengzhou University. Thirteen of the patients were male and ten were female, with age of (54.5±9.7) years (33-72 years). The numbers and types of perforators, the dimension of flap and the vascular pedicle length were measured. The outcomes of flaps and donor-site complication were recorded. The patients′ satisfaction with donor-site cosmesis were evaluated by the visual analogue scale (VAS). More than one sizable perforators was found in each case and the median number of perforators was 2 (range, 1 to 4), and all of the perforators were musculocutaneous. The pedicle length was (9.8±1.5) cm (range, 7.3 to 13.4 cm). The diameters of artery and the larger vein were 2.0 mm (range, 1.5 to 2.5 mm) and 2.0 mm (range, 1.5 to 3.0 mm), respectively. The dimension of the flaps ranged from 8 cm×6 cm to 12 cm×8 cm, and the donor sites were all closed primarily. All of the flaps were clinically survived, only one patient experienced partial wound dehiscence of donor site 14 days postoperatively and no donor site infection or permanent muscular weakness was reported. The VAS scores of the patients′ satisfaction with donor-site cosmesis were all more than 8. The perforators of the posteromedial thigh flap is consistent and the donor-site scar is well concealed, which make the posteromedial thigh flap an excellent option for oral and maxillofacial reconstruction.
