Brazilian Society of Otology task force - Otosclerosis: evaluation and treatment. Braz J Otorhinolaryngol 2023; 89:101303. [PMID: 37647735 PMCID: PMC10474207 DOI: 10.1016/j.bjorl.2023.101303] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/21/2023] [Accepted: 08/06/2023] [Indexed: 09/01/2023] Open
Abstract
OBJECTIVES To review and provide evidence-based recommendations for the diagnosis and treatment of otosclerosis. METHODS Task force members were educated on knowledge synthesis methods, including electronic database search, review and selection of relevant citations, and critical appraisal of selected studies. Articles written in English or Portuguese on otosclerosis were eligible for inclusion. The American College of Physicians' guideline grading system and the American Thyroid Association's guideline criteria were used for critical appraisal of evidence and recommendations for therapeutic interventions. RESULTS The topics were divided into 2 parts: 1) Diagnosis - audiologic and radiologic; 2) Treatment - hearing AIDS, pharmacological therapy, stapes surgery, and implantable devices - bone-anchored devices, active middle ear implants, and Cochlear Implants (CI). CONCLUSIONS The pathophysiology of otosclerosis has not yet been fully elucidated, but environmental factors and unidentified genes are likely to play a significant role in it. Women with otosclerosis are not at increased risk of worsening clinical condition due to the use of contraceptives or during pregnancy. Drug treatment has shown little benefit. If the patient does not want to undergo stapedotomy, the use of hearing aids is well indicated. Implantable systems should be indicated only in rare cases, and the CI should be indicated in cases of profound deafness.

Abstract
OBJECTIVES To compare hearing outcomes in patients with far advanced otosclerosis (FAO) undergoing cochlear implantation to an age-matched group of controls, to describe the effects of cochlear ossification on hearing, and to review the adverse effects of implantation in patients with FAO. HYPOTHESIS Hearing performance in patients with FAO after cochlear implantation is comparable to similarly treated postlingually deafened adults without FAO. Ossification or retrofenestral otosclerosis does not predict poor hearing outcomes. Modiolar-hugging technology reduces postoperative facial nerve stimulation. STUDY DESIGN Retrospective chart review. SETTING Academic neurotologic tertiary referral center. PATIENTS Thirty patients with FAO, who metaudiological criteria for cochlear implantation, were compared to 30 age-matched controls, postlingually deafened by non-otosclerotic causes. MAIN OUTCOME MEASURES Audiometric pre- and postoperative speech reception threshold, word, and sentence scores were analyzed. The presence of retrofenestral findings on computed tomography or intraoperative cochlear ossification were noted. RESULTS In the FAO group, radiographic abnormalities were noted in 26.4% of patients. Intraoperative ossification requiring drillout was seen in 29.4% of patients. None developed postoperative facial nerve stimulation. There was no difference between the FAO and control groups in the mean short-term and long-term postoperative speech reception threshold, word, and sentence scores (P = .77). The presence of radiographic abnormalities did not predict hearing outcome. Intraoperative cochlear ossification was not associated with worse short-term word and sentence scores (P = .58 and 0.79, respectively), and for the long-term hearing outcome (P = .24). CONCLUSIONS In patients with FAO, effective and safe hearing rehabilitation can be accomplished with cochlear implantation.

Abstract
HYPOTHESIS The purpose of this histopathological study is to examine temporal bones of patients with cochlear otosclerosis adjacent to the round window or adjacent to the oval window as compared with healthy controls. BACKGROUND It is unclear if the extent and site of otosclerosis affects the extent of damage to cochlear structures and hearing loss. METHODS Twelve temporal bones from 10 patients with cochlear otosclerosis adjacent to the round window, 11 temporal bones from 8 patients with cochlear otosclerosis adjacent to the oval window, and 12 bones of healthy age-matched controls were selected for study. We calculated the number of spiral ganglion cells, changes in cochlear structures, the extent and site of cochlear otosclerosis, and audiometric data. RESULTS The loss of spiral ganglion cells and the absence of outer hair cells in patients with cochlear otosclerosis adjacent to the round window were significantly higher than those in patients with cochlear otosclerosis adjacent to the oval window and healthy controls. The area of the spiral ligament in patients with cochlear otosclerosis adjacent to the oval window was significantly smaller than that in healthy controls. However, no significant difference was found in the spiral ligament of patients with cochlear otosclerosis adjacent to the round window and healthy controls. There was no significant difference between patients with cochlear otosclerosis and age-matched controls in audiometric data. CONCLUSION Cochlear otosclerosis adjacent to the round window caused significantly more damage to spiral ganglion cells and outer hair cells than cochlear otosclerosis adjacent to the oval window without loss of spiral ligament.

Abstract
Otosclerosis is a disease of the bony labyrinth manifesting clinically as a progressive conductive hearing loss, a mixed-type hearing loss, or a sensorineural hearing loss. The age of onset of the hearing loss caused by otosclerosis is principally between 15 and 40 years. Although histopathological inner ear changes due to otosclerosis have been very well documented, the true etiopathogenesis of the disease has yet to be described despite intensive research. Both genetic and environmental factors have been implicated, however.

Abstract
OBJECTIVE To assess the bone density around the bony labyrinth in otosclerosis patients and to compare it to that of a control population. MATERIAL AND METHODS This was a prospective case-control study. Ten patients with otosclerosis (mean age 42 years; range 24-55 years) and 33 control patients with vestibular schwannoma (mean age 46 years; range 20-71 years) were included. All patients underwent a clinical examination, audiometry and a CT scan comprising axial and coronal views of both temporal bones. In the otosclerosis group, audiometry showed unilateral involvement in six patients and bilateral hearing loss in four. The bone density was measured at the fissula ante fenestram (FAF) and at five other anatomical points on the bony labyrinth. RESULTS In the control group, the bone density was similar at the six anatomical points. In the otosclerosis patients, the mean bone density at the FAF was lower than that in control patients (1649+/-99.1 vs 2049+/-13.4 HU; p < 0.01). For patients with FAF bone densities < 2000 HU, a correlation was observed between hearing threshold and FAF bone density. CONCLUSION FAF bone density appears to be a good indicator of disease progression, and could serve as a follow-up and prognostic parameter.

Abstract
BACKGROUND The literature provides conflicting information regarding the prevalence and cause of sensorineural hearing loss (HL) in individuals with otosclerosis. OBJECTIVE The purpose of this study was to further evaluate the association between involvement of the cochlear endosteal layer with otosclerosis and sensorineural HL. STUDY DESIGN Retrospective case review. METHODS Temporal bones and audiograms from five individuals with otosclerosis were evaluated. The cochlear elements were quantified. The location and extent of the cochlear element loss was correlated with the location and extent of endosteal involvement with otosclerosis. RESULTS A reduction in the population of cochlear elements was observed in most individuals; however, the reduction was not proportional to the extent of endosteal involvement with otosclerosis. The cochlear elements remained normal adjacent to some areas of endosteal involvement with otosclerosis. One individual with extensive cochlear otosclerosis had normal hearing and predominantly normal cochlear elements. CONCLUSION This study demonstrates a variable amount of degeneration of the cochlear elements in individuals with otosclerotic involvement of the endosteum. The reduction in the population of cochlear elements was not related to the extent and location of endosteal involvement with otosclerosis. These findings suggest that factors that limit the effect of otosclerotic endosteal involvement on the cochlear elements or processes that effect the cochlear elements directly and are independent of bone involvement may be present.

Abstract
During the last century, hundreds of studies have been performed to identify factors that are involved in the aetiology of otosclerosis. These studies include a variety of aetiological factors and, although many theories have been postulated, the process of the development of the disease remains unclear. A historical overview and analysis of the literature dealing with the aetiology of otosclerosis is presented. The role of collagen disorders, genetic linkage studies, associations with the HLA system and measles virus infection as causal factors is discussed. From an epidemiological point of view, the disease has an autosomal dominant mode of inheritance. Therefore, since the introduction of new genetic research techniques over the last decades, more studies have been performed to find evidence of a genetic factor that initiates the development of otosclerosis. In this review, we tried to categorize the most prominent studies in sections according to their subjects within the diversity of aetiological factors that have been studied.

Abstract
OBJECTIVE To review current knowledge of the pathophysiology of otosclerosis and to review hypotheses for the amelioration of this disease. DATA SOURCES Review of the literature and experimental observations by the authors. CONCLUSIONS Otosclerosis is a localized disease of bone remodeling within the otic capsule of the human temporal bone. Unlike other similar bone diseases, it does not occur outside of the temporal bone. These lesions seem to begin by resorption of stable otic capsule bone in adults, followed by a reparative phase with bone deposition. There are clearly genetic factors that lead to this disease, but measles virus infection and autoimmunity also may play contributing roles. Surgical correction of the conductive hearing loss is highly effective, but nonsurgical intervention has not yet been shown to prevent or slow the disease. Of the factors that may inhibit this process, fluorides, cytokine inhibitors, and bisphosphonates, third-generation bisphosphonates appear to hold the most promise.

Abstract
Over the past few years, considerable advances have been made in the surgical treatment of glomus jugulare tumors. The long-term results of such surgery for cure of these tumors has yet to be established, however. We have reviewed the temporal bones of two patients who had glomus jugulare tumors. Such study provides a special opportunity to evaluate the major critical areas of involvement of these tumors, which bears on the long-term results of surgery, and is important in developing treatment to cure these benign, though aggressive, tumors.

Abstract
The modern stapedectomy with prosthesis insertion and living oval window seal, like the modern cataract extraction with lens replacement, is now performed, very much the same, throughout the world. I have reviewed the evolution of stapes surgery during these last thirty years and tried to gain some agreement for several important facts about otosclerosis and several basic principals of stapes surgery. While a well-performed stapedectomy can eliminate the conductive component, the sensorineural hearing loss continues and, in about one-third, will progress till the patient, after age 65, must return to a hearing aid. A piston prosthesis gives the best hearing results: 0.6 mm diameter, when half the footplate is removed and a living oval window seal interposed, and 0.6 mm diameter when a small opening is made in the footplate obliterated by otosclerosis. I prefer a teflon prosthesis to stainless steel because it can be altered by the surgeon at operation, and vein as an oval window seal. I have presented a rare group of patients who develop facial palsy 5-1/2 days after uncomplicated stapedectomy, of whom all recover quickly and completely. I am confident that progress will continue to be made in the understanding of otosclerosis, and the performance of stapes surgery, but in these last thirty years we have made a good beginning.
