颅底(颞骨)骨折常伴面神经损伤,据文献报道,其发生率为7～53%。当颞骨纵形骨折时,因面神经仍在骨管内,故损害轻,预后良好。纵形骨折引起听力损害为典型的传导性。横形骨折因骨折线由鼓室面神经管水平段经迷路前庭达内听道,通常导致面神经深部永久性损害和耳蜗前庭功能丧失。纵形骨折面神经损伤率为10～20%,横形骨折为30～50%。而本组则分别为12%(18/84)和37%(10/27)。颞骨骨折引起面神经损伤的治疗问题迄
Skull base (temporal bone) fractures often accompanied by facial nerve injury, according to the literature, the incidence was 7 ~ 53%. When the temporal bone longitudinal fracture, because the facial nerve is still in the bone canal, so the damage light, the prognosis is good. Longitudinal fractures caused by hearing loss is a typical conductivity. Transverse fractures due to fracture line by the tympanic canal horizontal segment of the vestibular tract by labyrinthine hearing loss, usually resulting in permanent facial nerve damage and loss of cochlear vestibular function. Longitudinal fracture facial nerve injury rate of 10 to 20%, horizontal fractures of 30 to 50%. This group was 12% (18/84) and 37% (10/27) respectively. Temporal bone fractures caused by the treatment of facial nerve problems
