摘　　要：目的　探讨LeForⅠ型截骨后眶下神经 (inferorbitalnerve,ION)暂时和永久性损伤的发生率和感觉恢复的时间。方法　随机选择 30例LeFortⅠ型截骨的病例 ,采用针刺检测、两点分辨觉法和直流感应电测仪测定ION分布区域感觉和恢复时间。结果　ION暂时性损伤为 75 % (4 5 6 0 ) ,ION感觉 1～ 3个月明显恢复。结论　LeFortⅠ型截骨后ION感觉障碍是暂时性的 ,一般在 1～ 3个月恢复 ,未见永久性神经损伤。Objective To investigate the incidence of the temporary and permanent sensory disturbance of the inferorbital nerve(ION) after Le Fort I osteotomy. Methods Thirty patients with 60 inferorbital nerves were examined preoperatively,1 week,1 month,3 months and 6-months after the operation of the Le Fort I osteotomy by using sharp-blunt testing,2-point discrimination,electric pain response test(ZGK-1 electrometer). Results The incidence of the temporary nerve impairment was 75% (45 of 60) and the obvious recovery was found after 1 to 3 months after the operation. No permanent sensory disturbance was found in the patients. Conclusions The inferorbital nerve injury after Le Fort I osteotomy is usually temporary and the sensory recovery was in 1 to 3 months after the operation. ;
