36 patients will be enrolled in a pilot trial. Eligible patients (receiving CI at OSU) that consent to participate into the study will be enrolled. A simulation with visualize cochlear substructures will be created for each patient, and surgeon will conduct virtual surgery with various cochlear implant electrode types and using different techniques for optimal positioning. Based on the feedback from the simulation platform, the surgeon will find the optimal CI electrode and surgical technique using the virtual simulation and a formal plan will be recorded to guide the actual surgery. Patient demographic information, medical history and pre op audiogram will be collected once enrolled. Post-op images will be used to identify the actual electrode location (scalar location (SL), modiolar distance (MD) and and angular insertion depth (AID). At 6- and 12-months post-op, word score (CNC) will be obtained as primary clinical outcomes and AZBio scores will also be obtained and evaluated as a secondary clinical outcome. All outcomes data to be collected for SA3 are considered as part of routine clinical care for patients undergoing CI at our institution. The prospective data collection plan will ensure these data will be collected timely with high quality. OSU IRB approval has been obtained for this study (OSU IRB# 2020H0080: Virtual Reality simulation for patient specific surgical rehearsal in cochlear implantation - OSU#2) pending additional amendments as needed.
The purpose of this study is to measure the potential effects of surgical drilling noise and/or vibration exposure on the hearing in the ear contralateral to the surgical site during skull-based surgeries
The purpose of this proposed study is to examine the benefits of using electropalatography (EPG) during speech therapy with adult individuals who are either congenitally deaf or adventitiously deaf and use a cochlear implant.
Pilot study to test the feasibility of translating the English language into haptics (touch sensations)
The lyric hearing device is a commercially available device produced by Sonova, and designed to be used for extended periods of time. We further want to investigate the morphology of the tissue around the device at different periods of time after the device has been fitted and used for a while. An initial imaging of the tissue will be taken for baseline measurements. Questionnaires will also be used to assess patients satisfaction with the device and cognitive abilities.
In this study, the investigators will evaluate whether auditory training with speech-related acoustic features in psychophysical testing will help CI subjects improve speech recognition. The primary endpoint is the speech recognition measures.
The purpose of this project is to validate a quick, easy-to-use and administer smartphone hearing-in-noise test. The Hearing-in-Noise Test (HINT) measures an individual's ability to hear speech in quiet and in noise. HINTs are traditionally done testing both ears together as binaural hearing ability is key in noisy settings and everyday, functional hearing. The app (called HearMe) can potentially be used to easily and quickly collect hearing-in-noise and speech-in-noise measurements. The smartphone app developed is a hearing-in-noise test that presents the subject with a series of stimuli consisting of a spoken three-digit sequence presented at a varying hearing-to-noise ratio. For each stimulus presentation, the user tap the three-digit sequence. The duration of the app is less than 3 minutes. For this project the investigators will test at least 50 subjects with hearing loss and 50 control subjects between the ages of 18-80. The subjects will be invited to take the app. The approach for this pilot study is to characterize hearing-in-noise thresholds (also referred to as a speech-reception threshold) as measured by the app in both subject groups, and relate it to the phenotype of each group as a preliminary evaluation of the app as well as a preliminary validation against their routinely collected measurements of hearing function (pure-tone audiometry thresholds). The study will assess the validity of the test construct in measuring hearing-in-noise thresholds, and serve as a foundation for further iterative designs of the app and future validation and characterization studies. This study seeks to validate a developed smartphone HINT on an initial cohort of patients and controls. It is anticipated that patients with hearing loss will display higher signal-to-noise ratio thresholds (as measured by the iPhone app) compared to controls.
The purpose of the study is to see if a commercially available hearing assistance device called the PockeTalker has an effect on performance on cognitive (memory and thinking) tests among skilled nursing facility residents. Investigators are asking residents to perform cognitive tests with and without hearing assistance equipment known as PockeTalkers. This study will be conducted at one urban Skilled Nursing Facility (SNF) with the goal of understanding the extent to which hearing impairment impacts commonly used cognitive impairment measures for clinical assessment. Cognitive performance will be measured, cerumen occlusion, and perceived hearing.
The purpose of this study is to identify factors that may contribute to conductive hearing loss. Conductive hearing loss is a type that is due to a problem with the outer or middle ear. Because of this, sound does not travel through the ear normally. Perforated tympanic membranes of study patients will be photographed during the patient's routine visit using a digital otoscope. These pictures will be used to analyze perforation size as an absolute value as well as a percentage of the tympanic membrane. Audiometric results and CT scans of temporal bone (reports and images) collected as standard of care will be evaluated. Images of CT scans will be imported into a medical imaging software for creation of anatomically realistic 3D models of the middle ear and mastoid air space. Structural analysis on each 3D model will be conducted and analyzed, the volume of middle ear and mastoid air spaces will be recorded, and data points will be correlated with perforation size and location to audiogram results.
