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...

HYPOTHESIS: The use of larger-diameter pistons in stapedotomy leads to better hearing outcomes compared with the use of smaller-diameter pistons. There is an interaction between stapes piston diameter and fenestration diameter. BACKGROUND: Otosclerosis can be treated surgically by removing part of the stapes and bypassing the stapes footplate with a prosthesis. Available piston shaft diameters range between 0.3 and 0.8 mm. There has been a tendency toward the use of smaller-diameter pistons, because of a suspected decreased risk of cochlear trauma and subsequent sensorineural hearing loss (SNHL) with smaller pistons...

Our aim was to critically assess the influence of preoperative computed tomography (CT) scans on implantation decisions for adult cochlear implant candidates. The working hypothesis was that these routine scans might not provide critical additional information in most adult cochlear implant candidates. The charts of 175 adults with unilateral cochlear implantation were reviewed. Preoperative CT scan reports were audited, and scans with reported pathology were examined by an Otologist/ENT Surgeon. Clinic notes and multidisciplinary team meeting summaries were also analyzed to assess whether the results of the radiology report had influenced the decision to implant or the laterality of implantation...

HYPOTHESIS: Assessing the maximum safe dose for local bisphosphonate delivery to the cochlea enables efficient delivery without ototoxicity. BACKGROUND: Otosclerosis is a disease of abnormal bone metabolism affecting the otic capsule, which can cause conductive hearing loss. Larger otosclerotic lesions involving the cochlear endosteum and spiral ligament can result in sensorineural hearing loss. Bisphosphonates are used to treat patients with metabolic bone diseases, including otosclerosis...

HYPOTHESIS: Ossification of the cochlea was once considered to be a contraindication for cochlear implantation. Advances in cochlear implant technology and coding strategies have led to developments in different surgical procedures to manage cochlear ossification. The endoscopic technique allows a direct approach to the round window and the cochlea, especially in remodeled labyrinth, allowing a better vision of scala tympani. BACKGROUND: Tertiary referral ENT center...

INTRODUCTION AND OBJECTIVES: Bone conduction threshold depression is not always a result of inner ear and cochlear nerve pathology. In fact, middle ear pathologies may be responsible for such threshold depression, as occurs in otosclerosis. The aims of this study were to evaluate the improvement of bone conduction threshold in patients with otosclerosis that underwent stapedectomy and to study the postoperative audiological results. MATERIAL AND METHODS: This was a retrospective study on 95 patients (116 ears) diagnosed with otosclerosis having conductive or mixed hearing loss that received surgery (stapedectomy and complete removal of the footplate) consecutively...

OBJECTIVE: This study aims to evaluate the increase in power of cochlear implants (CI) as the reference electrode (RE) position changes. Patients in whom it is necessary to use the full power of the device to achieve the desired stimulation levels, this strategy will ensure that stimulation capability is maximized. MATERIALS AND METHODS: The variability in RE placement in the temporal bone has a measurable effect on the electrical current, impedance, and power consumption, and if the electrode position has a functional effect on the stimulation intensity...

HYPOTHESIS: Drug delivered to the oval window can diffuse to the apex of the human cochlea. BACKGROUND: We have previously demonstrated that zoledronate, a nitrogen-containing bisphosphonate, can arrest the sensorineural hearing loss in cochlear otosclerosis. We have also shown that, in animals, delivery of bisphosphonate into the cochlea can dramatically increase delivery efficiency. Intracochlear drug delivery has the potential to increase local concentration of drug while decreasing the risk of systemic toxicity...

PURPOSE: Increased cochlear lymph fluid signals on three-dimensional fluid-attenuated inversion recovery (3D-FLAIR) images obtained several minutes after intravenous administration of a single dose of gadolinium-based contrast agent (IV-SD-GBCA) in a patient with severe retrofenestral type otosclerosis had been reported. This increase was thought to represent breakdown of the blood-labyrinthine barrier. The purpose of this study was to evaluate cochlear lymph signal on heavily T2-weighted 3D-FLAIR (HF) images obtained 4 hours after IV-SD-GBCA in patients with otosclerosis, Ménière's disease, and healthy subjects...
