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 M{\'e}ni{\`e}re 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.AMEIactive middle ear acoustic implantsELSendolymphatic sacLSClateral semicircular canalMCFmiddle cranial fossaPSCposterior semicircular canalSSCsuperior semicircular canalSSCDsuperior semicircular canal dehiscence}, issn = {0195-6108}, URL = {https://www.ajnr.org/content/42/1/12}, eprint = {https://www.ajnr.org/content/42/1/12.full.pdf}, journal = {American Journal of Neuroradiology} }
