Harvest of Vestibular End-Organs under Physiologic Conditions during Labyrinthectomy.

The living human inner ear is challenging to study because it is encased within dense otic capsule bone that limits access to biological tissue. Traditional temporal bone histopathology methods rely on lengthy, expensive decalcification protocols that take 9-10 months and reduce the types of tissue analysis possible due to RNA degradation. There is a critical need to develop methods to access fresh human inner ear tissue to better understand otologic diseases, such as Ménière's disease, at the cellular and molecular level.

Effects of triple semicircular canal plugging on hearing in patients with Meniere's disease: A systematic review and meta-analysis.

Introduction: Triple semicircular canal plugging is effective in controlling vertigo in patients with Meniere's disease, however, whether the rate of causing hearing loss during treatment is still not uniform. This study aimed to evaluate the effects of Triple semicircular canal plugging (TSCP) on hearing in Meniere's disease (MD) patients.

Methods: Databases Reviewed were PubMed, EMBASE, Scopus, Clinical Trials, Web of Science, Cochrane Library, CNKI, Wanfang, and VIP.

Study Design: Retrospective study in a tertiary care center.

Methods: 36 received ITMP injection and 52 EDB.

Otic Capsule Dehiscences Simulating Other Inner Ear Diseases: Characterization, Clinical Profile, and Follow-Up-Is Ménière's Disease the Sole Cause of Vertigo and Fluctuating Hearing Loss?

Introduction: We present a series of six cases whose clinical presentations exhibited audiovestibular manifestations of a third mobile window mechanism, bearing a reasonable resemblance to Ménière's disease and otosclerosis. The occurrence of these cases in such a short period has prompted a review of the underlying causes of its development. Understanding the pathophysiology of third mobile window syndrome and considering these entities in the differential diagnosis of conditions presenting with vertigo and hearing loss with slight air-bone gaps is essential for comprehending this group of pathologies.

Functional outcomes and caloric response changes after endolymphatic sac decompression.

Objective: To evaluate caloric response changes after endolymphatic sac decompression (ESD), together with hearing outcomes and the functional benefit of the operation.

Methods: A retrospective chart review of subjects who underwent endolymphatic sac decompression at a tertiary referral centre was performed. Data on audiological results, caloric testing, and functional level scale of the patients were analysed.

Occlusion of the Lateral Semicircular Canal, Endolymphatic Sac Surgery, and Cochlear Implantation: A Low Destructive Treatment for Unilateral Ménière's Disease and Deafness.

Introduction: Surgical treatment of Ménière's disease (MD) and deafness aims to treat vertigo and hearing disabilities. Current treatment options like labyrinthectomy and cochlear implantation (CI) have shown acceptable results but are destructive. Less destructive procedures, like the occlusion of the lateral semicircular canal and endolymphatic sac surgery, have been shown to be successful in vertigo control.

[Semicircular canal occlusion].

Semicircular canal occlusion（SCO） is a surgical technique widely used for treating vertigo symptoms. It is primarily aimed at treating benign paroxysmal positional vertigo（BPPV）, Ménière's disease（MD）, labyrinthine fistula, and superior semicircular canal dehiscence syndrome, among others. This review aims to comprehensively summarize the development, evolution, relevant basic research, and clinical applications of semicircular canal occlusion, especially the application of endoscopic technology in recent years, and explore its practical value in the field of surgical treatment for vertigo.

Treatment of Meniere's disease with simultaneous triple semicircular canal occlusion and cochlear implantation.

Objective: Report three cases of simultaneous triple semicircular canal occlusion (TSCO) and cochlear implantation (CI) as the treatment of intractable Meniere's disease (MD).

Case Reports: Patients with MD can present occasionally with intractable vertigo and profound sensorineural hearing loss (SNHL). TSCO and CI have been proposed to control vertigo and restore profound deafness in patients with MD separately.

Redox Modulation of Meniere Disease by Treatment, a Nutritional Mushroom Approach with Neuroprotective Potential.

Background: Meniere's disease (MD) is a cochlear neurodegenerative disease. Hearing loss appears to be triggered by oxidative stress in the ganglion neurons of the inner ear.

Objective: Here, we confirm the variation of markers of oxidative stress and inflammation in patients with Meniere and hypothesize that chronic treatment with Coriolus mushroom helps in the response to oxidative stress and acts on α-synuclein and on NF-kB-mediated inflammatory processes Methods: Markers of oxidative stress and inflammation were evaluated in MD patients with or without Coriolus treatment for 3 or 6 months.

Efficacy and preservation of hearing with low-dose gentamicin in unilateral meniere's disease: A clinical symptomatology-based study.

Purpose: Meniere's disease (MD), a disorder of the inner ear, presents numerous therapeutic challenges, and intratympanic (IT) gentamicin has been proposed for intractable cases. However, controversy regarding dosage and method persists. The purpose of this study was to assess the efficacy and safety of low-dose IT gentamicin on vertigo attacks in MD using a clinical symptomatology-based method, wherein administration was repeated only if vertigo attacks recurred, with a 2-week interval between injections.

Surgical labyrinthectomy in the treatment of unilateral Meniere disease: a Belgian retrospective study.

Purpose: Meniere's disease (MD) is a disabling condition with symptoms, such as hearing loss, dizziness, and tinnitus. Surgery is the last resort option for managing MD when other treatments are not effective. Surgical labyrinthectomy (SL) is less commonly performed than vestibular neurectomy or chemical labyrinthectomy.

Significance of endolymphatic sac surgery with and/or without simultaneous cochlea implant surgery in respect of vertigo control and speech perception in patients with Menière's disease.

Purpose: The focus on treating patients with Menière's Disease (MD) lies on the reduction of vertigo attacks and the preservation of sensory function. Endolympathic hydrops is considered as an epiphenomenon in MD, which can potentially be altered by endolymphatic sac surgery (ESS). Purpose of the study was to investigate the influences on vertigo control through manipulation of the perilymphatic system with or without ESS.

Iatrogenic inner ear dehiscence associated with lateral skull base surgery: a systematic analysis of drilling injuries and their causal factors.

Purpose: Drilling injuries of the inner ear are an underreported complication of lateral skull base (LSB) surgery. Inner ear breaches can cause hearing loss, vestibular dysfunction, and third window phenomenon. This study aims to elucidate primary factors causing iatrogenic inner ear dehiscences (IED) in 9 patients who presented to a tertiary care center with postoperative symptoms of IED following LSB surgery for vestibular schwannoma, endolymphatic sac tumor, Meniere's disease, paraganglioma jugulare, and vagal schwannoma.
