颞骨骨折性面瘫的临床和实验观察

Clinical and experimental study on facial paralysis in temporal bone fracture

为探讨影响颞骨骨折性面瘫预后的主要因素和面神经减压术的意义，总结分析了64例面瘫预后的主要相关因素。制作面瘫实验模型，测定面神经骨管开放组和非开放组面神经膨胀率，并行电镜观察。结果表明，影响预后的主要因素为是否行面神经减压术及手术时机。骨管开放组面神经膨胀率显著大于非开放组，非开放组神经纤维损伤程度重。提示早期行面神经减压术有利于面神经功能恢复。

To study the main prognostic factors and significance of facial nerve decompressionof facial paralysis in temporal bone fracture,the main relative prognostic factors of 64 patients withfacial paralysis were analyzed. Experimental model of facial paralysis was made. Expansion rate offacial nerve in facial canal opening group and non-opening group was measured and observed underelectron microscope. The main factors affecting the prognosis were facial nerve decompression andselection of surgery time. Expansion rate of facial nerve in opening group was significantly higherthan that of non-opening group. Injury degree of nerve fiber of non-opening group was severe.It issuggested that early facial nerve decompression is of beneficial to restoration of facial nerve function.
