Filter by:This is a pilot study of workshops to help Veterans with both vision and hearing loss live a happier, fuller and less stressful life. The results will be used to guide the development of a large scale clinical trial.
Cisplatin and carboplatin induce ototoxicity manifested as sensorineural hearing loss, tinnitus, and/or vestibular disturbances. Ototoxicity is induced via damage to inner ear structures by reactive oxygen species. Previous animal studies demonstrated that transtympanic injection of Ringer's Lactate (RL) provided near complete otoprotective effect against cisplatin. The purpose of this study is to determine if transtympanic administration of Ringer's Lactate via a pressure equalising (PE) tube in patients undergoing platinum based chemotherapy treatment will prevent tinnitus, vestibular dysfunction and hearing loss especially at high frequencies. Pre- and post- chemotherapy treatment audiometry will be measured and statistically analysed for significance.
The objective of this study is to assess the long-term safety and quality of life improvement of the Sonitus SoundBite Hearing System.
Hypothesis: Treatment for head and neck tumors often involve methods that affect the auditory system and cause hearing loss. Neck dissection negatively impacts the lymphatic drainage, chemotherapy uses ototoxic drugs, radiotherapy affects blood flow and tissue radiation is toxic to the ear and may lead to hearing losses of various types and degrees. Objective: To investigate occurrences of hearing loss and complaints among patients with head and neck tumors who underwent radiotherapy. Study design: Prospective, case-control study. Setting: Tertiary care center hospital. Subjects and Methods: 282 subjects were evaluated, 141 with head and neck tumors and 141 as an age-matched control group. The controls had never undergone oncological treatment that put their hearing at risk. All subjects underwent audiological evaluation, including the HHIE questionnaire, pure tone audiometry, speech audiometry and immittance audiometry. The radiation dose received by the auditory system was calculated based on the percentage of the external auditory canal included in the radiation field.
To evaluate the safety and efficacy of the Esteem Totally Implantable Hearing System in subjects suffering from mild to severe hearing loss.
Hearing loss is the most prevalent service-connected disability in the VA. It causes communication difficulties, which contribute to isolation, frustration and depression. A major cause of hearing loss is from exposure to high levels of sound, and is referred to as Noise Induced Hearing Loss (NIHL). Veterans have inevitably been exposed to high levels of sound during military service, and even though they may not yet have NIHL, their ears have been damaged. Continued noise exposure in civilian life will result in NIHL. However, it can easily be prevented by avoiding noise or using hearing protection. Most people are unaware that noise damages hearing, and even when they are, they do not use hearing protection. In this study we will use a randomized controlled trial to evaluate the short- and long-term effectiveness of two forms of education about NIHL that we have developed for Veterans. One is a computerized program; the other is a Hearing Conservation Brochure
This study measures sounds produced by the sensory receptors of the inner ear called hair cells. These sounds are called otoacoustic emissions and one special case the investigators are studying are called distortion product otoacoustic emissions (DPOAEs) produced by presenting two tones to the ear. If the ear is damaged by noise exposure DPOAEs are reduced. In this study the investigators are attempting to improve the DPOAE test by adding a third tone to make the test more frequency specific. Whether the third tone helps will be determined by comparing DPOAEs collected with and without the third tone to clinical audiograms. If the addition of the third tone helps then the investigators expect DPOAEs tracked as a function of frequency (DP-grams) will more closely match the clinical audiograms.
Seniors 65 years of age and older represent one of the fastest growing segments of society with the population doubling within the next 25 years with dramatic rates of mental decline, costing society billions of dollars each year. The proposed research seeks to discover whether relatively short term mental or physical training can enhance gist reasoning, generalize to untrained cognitive areas and modify/strengthen brain function in areas susceptible to aging processes. To identify neuroprotective and non-pharmacological interventions to prevent mental decline and maximize cognitive brain health during the course of the adult lifespan has major public policy implications.
The purpose of this study is to determine the safety and efficacy of using bone conduction via the teeth to treat Single-Sided Deafness (SSD).
The purpose of this study is to evaluate short and long term outcomes (benefits and side-effects) of bilateral cochlear implantation and bilateral hearing aid rehabilitation in Finnish children.
