面中骨折术后眶下神经损伤恢复的临床观察

Recovery of infraorbital nerve iujury after middle facial fracture

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作的患者,术后通过患者自述、针刺检测、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。

PURPOSE： To evaluate the recovery of infraorbital nerve injury after middle facial fracture. METHODS： 28 patients with infraorbital nerve injury were examined in 1 month, 5 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 nomlally.The average time of recovery was 25 weeks. The injured nerve didn＇t 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 pernlanent. If the injured nerve doesn＇t recover within 6 months, infraorbital nerve decompression may be selected to promote the recovery of the nerve function.
