游离皮瓣修复口腔癌术后缺损感觉恢复的研究

Sensory Recovery in the Noninnervated Free Flaps For Oral Reconstruction

目的:评估非感觉性游离皮瓣修复口腔癌术后缺损感觉功能的恢复情况。方法:追踪16例口腔癌患者,其中游离腓骨肌皮瓣修复下颌骨缺损8例,游离前臂皮瓣修复舌缺损8例,术后6-18个月检测移植后皮瓣的轻触觉、两点辨别觉、痛觉和冷热觉的恢复情况。结果:7例皮瓣(43.7%)至少2/3面积有感觉恢复,8例皮瓣(50%)有部分感觉恢复,1例皮瓣(6.3%)无感觉恢复。结论:非感觉性游离皮瓣修复口腔癌术后缺损可自行恢复部分感觉功能。

Objective： To evaluate sensory recovery in the noninnervated free flaps after oral reconstruction. Methods： Sixteen cases were included in this study： eight free fibula osseo-cutaneous flaps were employed for reconstruction of mandible and oral defects, and eight free radial forearm flaps for tongue defects. Flap sensations to touch, pain, two-point discrimination and warm vs cold were evaluated in each patients at time intervals ranging from 6 to 18 months after surgery. Results： Good sensory recovery manifested in seven flaps （43.7%）, eight flaps （50%） recovered partially, and one flap （6.3%） failed to recover sensation. Conclusion： Spontaneous return of partial sensation was documented in noninnervated free flaps after oral reconstruction.
