Sensorineural hearing loss results from abnormalities that affect the hair cells of the membranous labyrinth, inner ear malformations, and conditions affecting the auditory pathway from the cochlear nerve to the processing centers of the brain. Cochlear implantation is increasingly being performed for hearing rehabilitation owing to expanding indications and a growing number of children and adults with sensorineural hearing loss. An adequate understanding of the temporal bone anatomy and diseases that affect the inner ear is paramount for alerting the operating surgeon about variants and imaging findings that can influence the surgical technique, affect the choice of cochlear implant and electrode type, and help avoid inadvertent complications. In this article, imaging protocols for sensorineural hearing loss and the normal inner ear anatomy are reviewed, with a brief description of cochlear implant devices and surgical techniques. In addition, congenital inner ear malformations and acquired causes of sensorineural hearing loss are discussed, with a focus on imaging findings that may affect surgical planning and outcomes. The anatomic factors and variations that are associated with surgical challenges and may predispose patients to periprocedural complications also are highlighted.

感音神经性听力损失是由影响膜迷路毛细胞的异常、内耳畸形以及影响从蜗神经到脑处理中心的听觉通路的病症引起的。由于适应症不断扩大以及患有感音神经性听力损失的儿童和成人数量不断增加，越来越多地进行人工耳蜗植入以进行听力康复。充分了解颞骨解剖结构和影响内耳的疾病对于提醒手术医生注意可能影响手术技术、影响人工耳蜗和电极类型选择并有助于避免意外并发症的变异和影像学发现至关重要。在本文中，回顾了感音神经性听力损失的成像方案和正常内耳解剖结构，并简要描述了人工耳蜗装置和手术技术。此外，还讨论了先天性内耳畸形和感音神经性听力损失的后天性原因，重点是可能影响手术规划和结果的影像学发现。还强调了与手术挑战相关且可能使患者易发生围手术期并发症的解剖学因素和变异。RSNA，2023 本文的问答可通过在线学习中心获取。 以及
