前臂桡侧皮瓣移植供区手臂功能的回顾性研究

RETROSPECTIVE STUDY ON THE FUNCTION OF DONOR-SITE ARM UNDERGOING THE RADIAL FOREARM FLAP

目的 明确前臂桡侧皮瓣移植术对供区手臂功能的长期影响。方法 对 44例头颈部软组织缺损行前臂桡侧皮瓣重建病人的手术侧与非手术侧手臂的功能进行对比研究 ,感觉功能评价参照英国医学研究会 (BM RC)感觉功能评价标准并计百分比 ,运动功能评价采用配对t检验。结果 正中神经及尺神经分布区的感觉功能均在S4 水平 ;在桡神经分布区 ,79.6 %的感觉功能在S4 以下 ,93.2 %病人的感觉功能在S3 以上 ,仅 2例 (4.5 % )病人的感觉功能在S1水平。供区手臂的运动功能与非手术侧手臂无显著性差异 (P均 >0 .0 5 )。结论 前臂桡侧皮瓣移植术对供区手臂的运动功能以及正中神经、尺神经分布区的感觉功能无影响 ,桡神经分布区的感觉功能障碍较普遍 ,但感觉功能恢复较好。

Objective To understand the long-term effect of harvest of radial forearm free flap (RFF) on donor-site arm′s function. Methods Comparative study was performed on the unoperated and operated arms′ function in 44 patients undergoing RFF. The standard of BMRC grading was used to evaluate sensory functions, the motor function was assessed using paired t test. Results The patients′ sensory functions in median and ulnar nerve distributions were all at the level of S 4.In 79.6 % of the patients′, the sensory function in radial nerve distribution failed to recover to the level of S 4, with 93.2% of the patients showing sensory function above S 3,and 2 patients at the level of S 1. The motor function between operated and unoperated side demonstrated no significant difference (P>0.05). Conclusion The motor function of donor-site arm was not impaired by the harvest of RFF, nor was the sensory function in the median nerve and ulnar nerve distributions. Sensory disorder occurred frequently in radial nerve distribution, but the recovery was good.
