对脑脊液耳鼻漏的修复过去由神经外科医生经颅内途径手术。虽然经颅内途径可直接观察脑膜撕裂及邻近的脑组织;但是,其手术并发症发生率较高,易出现脑萎缩和嗅觉丧失等并发症,术后住院时间过长。经颅外途径手术对蝶窦、额窦及筛窦的暴露极佳,减少了上述并发症的发生率。虽然经该途径无法检查伴发的脑损伤;但是,如经CT扫描证实有颅内手术的必要,可采用颅内外联合途径。颅外途径手术包括经乳突、经鼻中隔蝶窦、鼻外筛窦切开 Rehabilitation of cerebrospinal fluid otorhino-leprosy was performed by a neurosurgeon via an intracranial approach. Although the meningeal tears and the adjacent brain tissue can be directly observed through the intracranial route, the incidence of complications is high, complications such as brain atrophy and loss of smell are easy to occur, and postoperative hospitalization time is too long. Extracranial surgery for sphenoid sinus, frontal sinus and ethmoid excellent exposure, reducing the incidence of these complications. Although the complication of brain injury can not be examined by this route, the intracranial and extracameral routes may be used if necessary for intracranial surgery confirmed by CT scan. Extracranial procedures include mastoid process, transnasal septal sphenoidosis, and extraocular ethmoid sinus surgery
