面中骨折术后眶下神经损伤恢复的临床观察

目的：观察面中骨折后眶下神经损伤的恢复状况。方法：对28例面中骨折后眶下神经损伤的患者，术后通过患者自述、针剌检测、两点辨别觉及直流感应电测仪测定眶下神经的恢复状况及恢复时间。采用SPSS12．0软件包对数据进行t检验。结果：25例患者的眶下神经损伤得到恢复，神经恢复时间在4-6个月，平均25周：3例患者未能恢复．成为永久性损伤。未发现慢性神经性疼痛患者。结论：大部分骨折后眶下神经损伤是暂时的、可恢复的，极少数为永久性损伤。对伤后6个月神经功能仍未恢复的患者，可考虑行眶下神经减压术。

Recovery of infraorbital nerve iujury after middle facial fracture

PURPOSE: To evaluate the recovery of infraorbital nerve injury after middle facial fracture. METHODS: 28 patients with infraorbital nerve injury were examined in l month, 3 months, 6 months and 12 months after operation by using sharp-blunt test, two-point discrimination,electric pain response test. The data were analyzed with SPSS12.0 software package for Student's t test. RESULTS: 25 cases (25 of 28) with injured nerve recovered normally.The average time of recovery was 25 weeks. The injured nerve didnot recover in 3 of 28. No chronic neuropathic pain was found. CONCLUSIONS: Most nerve dysfunctions following middle facial fracture are reversible and temporary,very few are permanent. If the injured nerve doesn't recover within 6 months, infraorbital nerve decompression may be selected to promote the recovery of the nerve function.
