Postoperative temporal bone imaging after surgical procedures such as ossiculoplasty, tympanomastoidectomy, cochlear implantation, and vestibular schwannoma resection is often encountered in clinical neuroradiology practice. Less common otologic procedures can present diagnostic dilemmas, particularly if access to prior operative reports is not possible. Lack of familiarity with the less common surgical procedures and expected postoperative changes may render radiologic interpretation challenging. This review illustrates key imaging findings after surgery for Ménière disease, superior semicircular canal dehiscence, temporal encephalocele repairs, internal auditory canal decompression, active middle ear implants, jugular bulb and sigmoid sinus dehiscence repair, and petrous apicectomy.
在临床神经放射学实践中，经常会遇到诸如听骨成形术、鼓室乳突切除术、耳蜗植入术和前庭神经鞘瘤切除术等手术术后的颞骨影像学表现。如果无法获得先前的手术报告，那么不太常见的耳部手术可能会带来诊断难题。如果对不太常见的手术程序和预期的术后变化不熟悉，可能会使影像学解释具有挑战性。本综述介绍了梅尼埃病、上半规管裂、颞骨脑膨出修复、内听道减压、主动中耳植入、颈静脉球和乙状窦裂修复以及岩尖切除术的术后关键影像学表现。
