Serdar Kaya, Michael M Paparella, Sebahattin Cureoglu
HYPOTHESIS: The density of vestibular dark cells (DCs) and vestibular transitional cells (TCs) can be quantitatively decreased in human temporal bones with otosclerosis. BACKGROUND: Previous reports have shown that otosclerosis can lead to vestibular symptoms. METHODS: We examined 61 human temporal bone specimens from 52 deceased donors with otosclerosis group-with and without endosteal involvement (EI), and with and without endolymphatic hydrops (EH)-versus 25 specimens from 18 age-matched controls...

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 The latter is obsolete for diagnostic intentions.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...

CONCLUSION: The NiTiBOND(®) prosthesis allows early results to be obtained similar to those with a manually crimped prosthesis fitted by experienced surgeons, thus reducing the learning curve in this critical step of the procedure. OBJECTIVE: To analyze the 1-month results using the nitinol NiTiBOND(®) prosthesis in primary otosclerosis surgery and to compare the results with those obtained with fully fluoroplastic or fully titanium pistons. MATERIALS AND METHODS: Fifty consecutive cases operated on with the NiTiBOND(®) prosthesis (nitinol group) were compared with 50 cases operated on with a fully fluoroplastic piston (fluoroplastic group), and with 131 cases operated on with a fully titanium piston (first titanium group), and also with 50 cases operated on with the same titanium piston just before using the NiTiBOND(®) piston (last titanium group)...

CONCLUSIONS: The presence of endolymphatic hydrops (EH) in the vestibule on magnetic resonance imaging (MRI) might be a high-risk factor for complications in cases that are candidates for stapes surgery. OBJECTIVE: Pre-operative detection of EH could be valuable in cases that are candidates for stapes surgery to prevent unpredictable complications following surgery. Pre-operative MRI findings and post-operative findings following stapes surgery were compared to evaluate the efficacy of such MRI evaluation for the management of cases with otosclerosis...

Congenital middle ear malformations are rare. Most part of them are usually associated with other malformations, such as aural atresia, microtia, and dysmorphic craniofacial features. A clinical case of a 24-year-old male with a right-sided conductive hearing loss since his childhood, without craniofacial malformation, is presented. He was proposed for exploratory tympanotomy under the suspicious diagnosis of otosclerosis. The surgery revealed an abnormal location of stapes' superstructure, which was attached to the promontory and had an isolated and mobile osseous footplate in the oval window...

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...

This chapter will focus on vertigo/dizziness due to inner-ear malformations, labyrinthine fistula, otosclerosis, infectious processes, and autoimmune inner-ear disorders. Inner-ear malformation due to dehiscence of the superior semicircular canal is the most recently described inner-ear malformation. Vertigo/dizziness is typically induced by sound and pressure stimuli and can be associated with auditory symptoms (conductive or mixed hearing loss). Labyrinthine fistula, except after surgery for otosclerosis, in the context of trauma or chronic otitis media with cholesteatoma, still remains a challenging disorder due to multiple uncertainties regarding diagnostic and management strategies...

CONCLUSIONS: Osteoclasts are unlikely to be involved in bone resorption in middle ear cholesteatoma. OBJECTIVE: The authors searched for osteoclasts in undecalcified bone sections in patients with middle ear cholesteatoma to determine whether and to what extent these cells are involved in this disease. METHODS: Twelve patients, eight men and four women, aged 30-87 years, who underwent tympanomastoidectomy were enrolled. Six patients had primary acquired middle ear cholesteatoma (cholesteatoma group) and the other six patients had other otologic diseases including otosclerosis, non-cholesteatomatous chronic otitis media, adhesive otitis media, perilymphatic fistula and ossicular malformation (control group)...

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...

CONCLUSION: The incidence of taste disturbance after stapes surgery is high (61.9%), whereas the majority (94.8%) recovers within 1 year. More severe surgical nerve trauma caused more disturbance, implying that the nerve should be handled carefully during surgery. OBJECTIVES: Patients operated on for otosclerosis seem more often to complain about post-operative taste disturbance than those operated on for chronic otitis media, although the chorda tympani nerve more seldom becomes maltreated in stapedotomy...

The objective of the present study was to analyze the potential of cone beam computed tomography of the temporal bones in the patients presenting with otosclerosis for the detection of surgically significant specific structural features of the labyrinth wall of the tympanic cavity. More than 400 tomograms of the temporal bones were obtained with the use of a cone beam tomographwere available for the investigation during the period from 2012 till 2016. The study was carried out in several steps, viz. the search for the optimal (for the given instrument) position of the patient, the experimental stage, the retrospective analysis of the tomograms and the comparison of the temporal bones of different types (pneumatic, mixed, and sclerotic) in individual patients, the comparison of the results of cone beam computed tomography (CBCT) with the intraoperative observations, and the modification of the algorithm for the analysis of temporal bone cone beam tomograms...

INTRODUCTION: Meniere's disease is a disorder of the membranous labyrinth of the inner ear manifesting as vertigo, tinnitus, sensory neural hearing loss and aural fullness of known or unknown origin. Some patients may present after years into typical forms. The endocrine disorders, especially hypothyroidism and the factors like inflammation, trauma, otosclerosis, autoimmunity explains the multifactorial causation for the basis of Meniere's disease. Endolymphatic hydrops is the pathologic term named for the defective regulation of endolymph volume with respect to production and absorption...
