BACKGROUND: Otosclerosis is a common cause of progressive hearing impairment that causes fixation of the stapes. Surgical intervention is the preferred treatment approach to ameliorate the conductive hearing loss associated with stapedial otosclerosis. However, given that it is a difficult and delicate procedure, the surgery may fail for a number of reasons. Therefore, it is very important to evaluate the success rate of the surgical approach used in each regional center. OBJECTIVE: To examine the effectiveness of stapedotomy in improving hearing sensitivity for otosclerotic patients at King Abdul Aziz University Hospital in Riyadh...

Background Otosclerotic foci are usually seen as minute low-density lesions and this may be attributed to relatively low sensitivity on visual assessment using computed tomography (CT). Otosclerotic foci can be detected by using the accurate region of interest (ROI) setting, while small ROI settings by less-experienced radiologists may result in false negative findings. Purpose To evaluate the diagnostic ability of our proposed method ("otosclerosis-weighted" imaging [OWI]), which is based on reversing the density, compared with conventional CT (CCT) imaging alone...

BACKGROUND: Sensorineural complications of stapes surgery are rare but potentially serious. Imaging is usually performed to identify an underlying cause, such as excessive intravestibular penetration of the prosthesis or pneumolabyrinth suggesting perilymphatic fistula. Unfortunately, there is very little data in an unselected series of uneventful patients.The aim of this study was to analyze the depth of prosthesis penetration within the vestibule and the rate of pneumolabyrinth the day or the day after the procedure by performing a cone beam computed tomography of the temporal bone in a cohort of unselected patients, and to correlate imaging findings to clinical outcome...

Otosclerosis is a complex and progressive disease of pathological bone remodeling that affects the otic capsule of the temporal bone, resulting in hearing loss. Although traditional diagnostic methods are still used, improvements in technology and research have paved the way for additional diagnostic techniques and advancements. The traditional treatment of otosclerosis, stapes surgery, is now being augmented or replaced by innovations in hearing aid technology and cochlear implants. Earlier diagnosis of otosclerosis can occur through understanding of the cause, risk factors, and current diagnostic testing...

In this article, we present four patients who underwent cochlear implantation due to far advanced otosclerosis. Preoperative evaluations, intraoperative findings, complications, and postoperative benefits were analyzed. Cochlear implantation is a treatment option providing excellent audiological results for rehabilitation of patients with far advanced otosclerosis. However, facial nerve stimulation after cochlear implantation is observed more frequently in patients with otosclerosis. Also, caution should be paid in patients with otosclerosis in terms of cochlear ossification and inconsistent results...

This article describes the current significance of computed tomography (CT), magnetic resonance imaging (MRI), cone beam CT, digital subtraction angiography (DSA), and special X‑rays in the diagnostics of temporal bone diseases. The latter is obsolete for diagnostic intentions. Possibilities and limitations in terms of detection and/or depiction of the extent of inflammatory, traumatic, tumorous, and postoperative pathologies are discussed. A concrete question and conveyance of clinical findings influence the choice of the method to be applied in the individual case...
