作者基于对面部感觉神经的损伤一直未引起人们注意的情况,对面部感觉神经的病变进行了外科治疗研究。该文着重对眶下神经的解剖,损伤的发病机理、病理,手术指征,外科技术以及手术效果进行了讨论。作者用显微外科方法对10具尸体(20条神经)进行了解剖,揭示眶下神经由5～6束神经束组成与动静脉共同在疏松的结缔组织鞘内。多数情况下,神经在管内居于中上位,静脉在中下位,动脉在侧位。眶下神经损伤主要由于外科手术(如肿瘤切除),骨折造成。骨折后由于骨移位造成对神经的压力,眶下神经管由于骨折变狭窄(外压)及血管破裂引起血肿(内压)导致传导障碍。内外压使微循环发生障碍,改变了局部代谢,引起酸中
The author based on the damage to the facial sensory nerve has not been people's attention to the situation, the surgical treatment of facial sensory nerve lesions. This article focuses on the anatomy of the infraorbital nerve, the pathogenesis of injury, pathology, surgical indications, surgical techniques and surgical effects were discussed. The authors used microsurgery to dissect 10 bodies (20 nerves), revealing that the infraorbital nerve consists of 5 to 6 fascicles and arteriovenous connective tissue in the loose connective tissue sheath. In most cases, the nerves are located in the upper middle of the duct, the veins are in the lower and middle positions, and the arteries are in the lateral position. Infraorbital nerve injury is mainly due to surgery (such as tumor resection), fractures caused. After the fracture due to bone displacement caused by nerve pressure, infraorbital nerve tube due to stenosis (external pressure) and rupture of blood vessels caused by hematoma (internal pressure) lead to conduction disorders. Internal and external pressure to microcirculation obstacles, changing the local metabolism, causing acid
