Effects of Cervical Mobilization on Dizziness, Balance, and Joint Position Sense in Patients With Meniere's Disease

The study will employ a stratified randomization method. Patients presenting to the Afyonkarahisar Health Sciences University Health Application and Research Center, Ear, Nose, and Throat Outpatient Clinic, with a definitive diagnosis of Meniere's disease, unilateral or bilateral involvement, and who consent to participate in the study will be divided into three groups. The control group will receive only their routine Betahistine. Their usual treatment will remain unchanged. The first study group will receive 20 minutes of Vestibular Rehabilitation (VR) and 10 minutes of cervical mobilization in addition to their routine Betahistine. The second study group will receive 30 minutes of VR in addition to Betahistine. The study will last 6 weeks. Participants will be assessed using a sociodemographic information questionnaire, the Dizziness Handicap Inventory (DHI), the Vertigo Symptom Scale (VSS), the Neck Disability Index (NDI), the International Tinnitus Inventory (ITI), balance assessment with the K-Force Plates, and joint position sense and proprioception assessment with the Kinvent Physio K-Move. All assessments will be conducted twice, before and after treatment.

CI Following VS Removal or Labyrinthectomy

This study is a prospective, clinical study to determine if it is safe and effective to use a cochlear implant over time in individuals undergoing removal of a vestibular schwannoma (VS), benign tumor of the hearing and balance nerve or undergoing a labyrinthectomy for treatment of Meniere's disease. Individuals undergoing these surgeries will be deaf on the surgical side after the procedure. Currently, cochlear implants are approved for use and not considered investigational in individuals with hearing loss on both sides. However, use of a cochlear implant for these patient populations (single-sided hearing loss) will be considered a new use of an approved device. Participants undergoing surgery to remove a VS or having a labyrinthectomy will have a cochlear implant inserted after the surgical procedure for clinical care. Approximately 4 weeks after surgery, participants will be fitted with an external speech processor on the surgical side that will stimulate the internal cochlear implant. Participants will return at the following intervals after the initial processor fitting: 2 weeks, 1 month, 3 months, 6 months, 9 months, and 12 months. At each interval, participants will complete questionnaires on how they are hearing with the implant and their quality of life with the implant and be tested on their ability to hear sounds and understand speech. Potential risks are those associated with all cochlear implant surgeries, and include device failure resulting in removal of device, irritation or redness in surgical area and/or area where processor is attached, increased ringing in the ear, facial nerve stimulation and a change in the way speech and other sounds sound through the implant. Potential benefits to individual participants in this study include improvement in detection and speech understanding of the surgical ear. Participants may also experience improved abilities to locate sound and understand speech in noise as the result of having hearing on both sides.

Repurposed Use of Allergic Rhinitis and Allergic Asthma Drug to Reduce Vertigo and Hearing Loss in Meniere's Disease

The purpose of this study is to evaluate a previously FDA-approved medication that is known to help with allergy symptoms to see if it can decrease symptoms in patients with Meniere's Disease.

Effect of Peripheral Vestibular Disease Location on Outcomes Following Home-based Virtual Reality Vestibular Therapy

This parallel-group randomized controlled trial aims to determine if the location of the lesion(s) in the vestibular system (unilateral versus bilateral, lateral semi-circular canal versus otolith) impacts the effectiveness of adjunct take-home head-mounted display (HMD) virtual reality (VR) therapy in improving patient symptomatology. Fifty patients meeting inclusion criteria will be recruited from the principal investigator's neurotology clinic. Baseline symptomatology questionnaires will be completed, followed by random allocation to virtual reality and control groups. Vestibular rehabilitation and virtual reality protocols will be adhered to for 4 to 8 weeks, followed by symptomatology questionnaires. Data analysis will be conducted to answer the study's objectives.

Laser Acupuncture for Meniere Disease

Objective: To evaluate the effect of laser acupuncture for the patients Meniere disease. Methods: We enrolled 324 patients at Beijing Tongren Hospital. Patients completed outcome measures at baseline, 3 months, 6 months, and 12 months. Video head impulse test (vHIT), The Caloric Test, Tinnitus Handicap Inventory (THI), Dizziness Handicap Inventory (DHI), Pure Tone Audiometry (PTA), and visual scale of ear stuffiness to evaluate the therapeutic effects. A difference of P \< 0.05 was considered statistically significant.

Imaging of Endolymphatic Hydrops at 7T MRI

Imaging endolymphatic hydrops with 7T Sodium Imaging and 1.5 T gadolinium enhanced imaging: a comparison of diagnostic outcomes with 3T MRI Duration of study 24 months Study design Prospective cohort study Number of patients 16 patients 1. To evaluate whether imaging both 1.5T and 3T have an equivalent performance in terms of diagnosing MD ears with delayed post gadolinium enhanced MRI (applying quantitative and semi-quantitative analysis) 2. To compare the diagnostic performance of Sodium Imaging at 7T (applying semi-quantitative analysis) with that of delayed post gadolinium enhanced 3T MRI in distinguishing symptomatic from asymptomatic Meniere's Disease (MD) ears.

The Effecttiveness of Intratympanic Methylprednisolon Injections Compared to Placebo in the Treatment of Vertigo Attacks in Meniere's Disease

Ménière's disease is an inner ear disorder in which patients suffer from attacks of vertigo, tinnitus and hearing loss. To date, it is unclear what the best treatment for this condition is. Giving injections in the inner ear with the adrenal cortical hormone methylprednisolone is a treatment that is already widely used, but still there is insufficient evidence in the effectiveness of this treatment. This multicenter trial compares a patient group which receives injections of methylprednisolone to a patient group which receives placebo injections. Subsequently, dizziness, tinnitus, hearing loss and quality of life will be assed and compared for the above mentioned groups, over a period of one year.

Menier's Disease - Bone Density Study

Meniere's disease is a progressive and debilitating inner ear disease characterised by vertigo and hearing loss. Several studies have linked Menierws disease with lower bone density and lower vitamin D levels. In the current prospective study definite Meniere's patients will be followed over a period of 2 year, during which repetitive measurements of bone density, vitamin D plasma levels, blood pressure as well as hearing and vestibular tests will be made. Results will be compared to healthy controls.
