The purpose of this study was to evaluate the long-term functional and esthetic outcomes of radial forearm flap (RFF) donor site repaired with split thickness skin graft (STSG). Nineteen patients underwent surgical reconstruction of oro-facial defects by the use of RFF and their donor sites were reconstructed with STSG. The patients were followed up at least for 12 months postoperatively and the left hand was the non-dominant hand in all of them. Objective methods including pinch strength, grip strength, range of motion, current perception threshold (CPT) and two-point discrimination, and subjective methods including patients interview, visual analogue score (VAS) about function, sensitivity, pain and color match, were collectively employed for donor site assessment. Our data revealed some degree of reduction in motor function and sensation compared to the non-donor hand. The difference of pinch strength means was 9.81% and of the grip strength was 12.6%. The difference of wrist flexion means was 17.6% and of wrist extension was 13.4%. However, none of the patients had functional defects of forearm supination and pronation, wrist ulnar deviation or wrist radial deviation. Subjective evaluation showed that the donor site repaired with STSG was well accepted by the patients particularly from a functional point of view. These results demonstrate that STSG represents a favorable choice for RFF donor site repair.
本研究旨在评估游离前臂皮瓣（RFF）供区采用断层皮片（STSG）修复后的长期功能和美观效果。19 例患者因口腔颌面缺损接受了 RFF 手术重建，其供区采用 STSG 修复。所有患者均至少随访 12 个月，且左手均为非优势手。采用客观方法（包括捏力、握力、关节活动度、电流感觉阈值（CPT）和两点辨别觉）和主观方法（包括患者访谈、功能、感觉、疼痛和颜色匹配的视觉模拟评分（VAS））对供区进行评估。我们的数据显示，与非供区手相比，手部运动功能和感觉有一定程度的下降。捏力均值差异为 9.81%，握力均值差异为 12.6%。腕关节屈曲均值差异为 17.6%，腕关节伸展均值差异为 13.4%。然而，所有患者均无前臂旋前和旋后、腕尺偏或腕桡偏功能缺陷。主观评估显示，采用 STSG 修复的供区被患者很好地接受，尤其是从功能角度来看。这些结果表明，STSG 是 RFF 供区修复的一种较好选择。
