前臂游离皮瓣修复口腔颌面部软组织缺损的远期疗效

LONGTERM RESULT OF FREE FOREARM SKIN FLAP FOR REPAIR OF SOFT TISSUE DEFECTS OF THE ORAL AND MAXILLOFACIAL REGIONS

为了对前臂游离皮瓣在修复口腔颌面部癌肿切除后软组织缺损中的远期疗效进行评价，对１９８５年６月～１９９４年５月间施行该手术的２６例患者作了平均４年６个月的随访。通过检测皮瓣的外形、颜色、质地、温度、感觉、粘膜化程度，前臂供区的外形，手的血供和对手功能的影响等项目，进行了综合分析。２０例中受区综合功能均为优；供区综合功能优１６例，疗效稍差４例。原因是游离皮瓣时切断桡神经浅支所致。认为，前臂游离皮瓣在治疗口腔颌面部软组织缺损中仍是一个值得应用的好方法。

To evaluate the longterm result of free forearm skin flap in the repair of soft tissue defects of the oral and maxillofacial regions, 26 cases which had received radical resection of maxillofacial tumors were follow-up for 4.5 years. Twenty cases, having complete data were analyzed. In this series, There were 8 males and 12 females, with ages ranged from 40 to 69 years old. The size of the flaps ranged from 4cm×5cm～6cm×13cm. The radial artery and the cephalic vein were used as the donor vessels, and the maxillary artery, superior thyroid artery, external jugular vein and the anterior jugular vein were prepared as the recipient vessels. According to the shape, colour, temperature, sensation, mucosoid degree of the flap, the blood supply and function of hand and the configuration of the forearm, the overall results of the recepient regions in 20 cases were all satisfactory and the overall results of 16 cases donor regions were satifactory in 16 cases. The results were poor in 4 cases. The conclusion were: ①Free forearm skin flap was worth trying in the repair of soft tissue defects of oral region; ②The radial artery need not to be reconstructed because of the abandant vascular network in the upper limb and ③The residul scar on the forearm was the main shortcoming, but most of the patients could tolerate it because of the obvious advantages received from the operation.
