Vestibular Precision: Physiology & Pathophysiology
Vestibular SchwannomaInner Ear Disease3 moreThis project will investigate the role of noise in the vestibular system, and in particular its effects on the variability (precision) of vestibular-mediated behaviors. The investigators will study vestibular precision in normal subjects and patients with peripheral vestibular damage, and will investigate its potential plasticity. The goals are to develop a better understanding of the role noise plays in the vestibular system in normal and pathologic populations, and to determine if the brain can learn to improve signal recognition within its inherently noisy neural environment, which would result in improved behavioral precision.
Deep Phenotyping of Hearing Instability Disorders: Cohort Establishment, Biomarker Identification,...
Meniere's DiseaseEnlarged Vestibular Aqueduct Syndrome1 moreBackground: Disorders of hearing instability (HI) are poorly characterized and ineffectively treated. HI can cause fluctuations in hearing thresholds and speech understanding. Researchers want to use a specialized form of magnetic resonance imaging (MRI) and blood tests to learn more about HI. Objective: To characterize a cohort of people with HI and to correlate HI with other data, including hearing evaluations, as well as radiologic and immunologic biomarkers of inflammation over time. Eligibility: Adults ages 18-80 who have symptoms consistent with possible HI. Design: Participants will be screened with a medical and hearing history and medical record review. Participants will have physical exams. Their head and neck will be examined. They will have blood drawn. Participants will have hearing tests. They will wear headphones or foam earplugs. They will listen to different tones. They may describe what they hear. Participants will have balance tests. They will wear goggles as they watch moving lights or while cold or warm air is blown into their ears. They will sit in a spinning chair in a quiet, dark booth. From a reclining position, they will raise their head while clicking sounds are played into their ears. Participants will have MRIs of the inner ear and brain. The MRI scanner is a metal cylinder surrounded by a strong magnetic field. During the MRIs, participants will lie on a table that slides in and out of the scanner. Soft padding or a coil will be placed around their head. They will get a contrast agent through an intravenous catheter. Participation will last up to 15 months. ...
Interest of Wicking for Ossicular Surgery and Myringoplasty
Post-Op ComplicationOtologic DiseaseMyringoplasties and ossicular surgery are very common procedures. Following these otological surgeries, most surgeons install a wicking. This intervention consists of placing a wick, absorbable or not, in the external acoustic meatus, after having replaced the tympanomeatal flap.
Effect of Peripheral Vestibular Disease Location on Outcomes Following Home-based Virtual Reality...
Peripheral Vestibular DisorderBenign Paroxysmal Positional Vertigo5 moreThis 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.
Optical Coherence Tomography of the Middle Ear Using Ossiview
Middle Ear DiseaseThe aim of this study is to understand the diagnostic applications for this imaging technology and identify particular disorders to target for future clinical investigations. Images obtained with the Ossiview device will be correlated to other standard of care (SoC) testing including microscopic otoscopy, CT scans, MRIs, audiologic testing results, and surgical and pathology reports.
Intratympanic Injection for Autoimmune Inner Ear Disease
Autoimmune Inner Ear DiseaseThe investigators plan to conduct an open-label intratympanic injection proof-of-concept trial of golimumab, a TNF-alpha inhibitor, assessing for hearing loss progression in patients with autoimmune inner ear disease (AIED). This specific aim will be achieved using a two-arm approach. First, the investigators propose to dose 3 individual subjects with a single intratympanic injection of golimumab and follow each for 30 days, closely examining them for adverse events. If there are no serious adverse events, with FDA approval, the investigators propose to dose 14 subjects, each with 4 intratympanic injections of golimumab.
Feasibility of Stereotactic Image Guidance on the Lateral Skull Base
Otologic DiseaseA clinical trial to asses the accuracy, usefulness and usability of a stereotactic image-guidance system during lateral skull base surgery.
Implantation of the HiRes90K™ Advantage Cochlear Implant With HiFocus™ Mid-Scala and Development...
Hearing LossPartial Deafness3 moreThe purpose of this feasibility study is to evaluate whether low-frequency acoustic hearing sensitivity can be preserved in newly implanted adults with partial deafness (considerable low frequency acoustic hearing profiles with severe-to-profound high frequency sensorineural hearing loss) using the HiResolution™ 90K™ Advantage cochlear implant with the HiFocus™ Mid-Scala electrode to support the development of electro-acoustic stimulation technology (EAS).

Hearing LossDeafness3 moreThe purpose of this study is to determine the feasibility of preserving low-frequency acoustic hearing in adults with a moderate degree of hearing loss in the low frequencies and severe-to-profound hearing loss in the mid-to-high frequencies who are implanted with the HiRes™ 90K Advantage implant with HiFocus™ Mid-Scala electrode.
Clinical Effect of Panfoxol of Otolaryngological Diseases of Upper Respiratory Tract Infection:...
Otologic DiseasePatients with otolaryngological diseases caused by upper respiratory tract infections, including allergic rhinitis, chronic rhinosinusitis, secretory otitis media, and oblate gland hypertrophy, were treated with all drugs from Sun Yat-sen Memorial Hospital of Sun Yat-sen University, the First Affiliated Hospital of Sun Yat-sen University, Guangdong Provincial People's Hospital, and Guangdong Provincial Hospital of Traditional Chinese Medicine from January 2021 to December 2022. According to the treatment methods, the patients were divided into panfosol + conventional treatment group and conventional treatment group for multicenter retrospective analysis.
