Objective Superior semicircular canal dehiscence (SSCD) causing conductive hearing loss with present reflexes is a known reason for stapes surgery failure. However, concomitant SSCD and otosclerosis occur rarely. We present a case series of SSCD diagnosed in positively identified otosclerosis patients. Methods Retrospective review of clinical case series in two tertiary‐referral neurotologic practices was performed. Clinical histories, operative findings, audiograms, and computed tomography (CT) images were reviewed for patients diagnosed with both SSCD and otosclerosis. Patients with present stapedial reflexes were excluded. Comprehensive literature review was performed. Results Four cases were identified. Three reported improved hearing with partial or complete closure of the air‐bone gap (ABG), including one patient with far‐advanced otosclerosis. One patient had no improvement in pure tone average or ABG. One patient reported worsening of preoperative autophony and pulsatile tinnitus, but none developed new postoperative third‐window symptoms. CTs demonstrated both SSCD and otosclerosis. Conclusion Failure to close the ABG in patients with positively identified otosclerosis intraoperatively may be due to SSCD as an occult concomitant diagnosis. SSCD should be considered as a possible cause of persistent conductive hearing loss after stapes surgery. Level of Evidence 4 Laryngoscope, 130:1023–1027, 2020

Imaging Review of the Temporal Bone: Part II. Traumatic, Postoperative, and Noninflammatory Nonneoplastic Conditions

The first part of this review of the temporal bone discussed anatomy of the temporal bone as well as inflammatory and neoplastic processes in the temporal bone region (1). This second part will first discuss trauma to the temporal bone and posttraumatic complications. The indications for common surgical procedures performed in the temporal bone and their postoperative imaging appearance are then presented. Finally, a few noninflammatory nonneoplastic entities involving the temporal bone are reviewed. They are relatively uncommon diagnoses compared with infectious or inflammatory diseases. However, because patients present with symptoms that are either common (hearing loss) or distinctive (sensorineural hearing loss in a child), they are important for the radiologist to be aware of and recognize.

“…It is believed that the acquired otosclerotic oval window occlusion can mask the presence of a “third inner ear window” by eliminating the function of the oval window. Symptoms of superior semicircular canal dehiscence maybe unmasked by surgery to remove fixation of the stapes reflected by lack of or incomplete hearing improvement, the appearance of vestibular symptoms, or combination of both …”

“…Because of the rarity of symptomatic superior semicircular canal dehiscence and the fact only about half of the otosclerotic ears undergo stapes operation, the combination of otosclerosis with post‐stapedectomy apparent superior semicircular canal dehiscence is rare. As a result, publications of clinical cases are restricted to several case reports and small series, summed up to 12 patients (13 ears) . This is a review of the clinical presentation and post‐operative outcomes of patients with superior semicircular canal dehiscence after stapes surgery.…”
