Dramatic results from recent animal experiments show that noise exposure can cause a selective loss of high-threshold auditory nerve fibers without affecting absolute sensitivity permanently. This cochlear neuropathy has been described as hidden hearing loss, as it is not thought to be detectable using standard measures of audiometric threshold. It is possible that hidden hearing loss is a comm...

OBJECTIVE Partial deafness cochlear implantation and electric-acoustic stimulation have proven to be a useful method of treating adults with a ski-slope type hearing loss. Good hearing preservation and speech perception outcomes have been reported. This study aims to assess partial deafness cochlear implantation in children. METHOD Nine children, ranging in age from 4.2 to 12 years, received ...

Children with hearing loss are at risk for lower self-esteem due to differences from hearing peers relative to communication skills, physical appearance, and social maturity. This study examines the influence of generic factors unrelated to hearing loss (e.g., age, gender, temperament) and specific factors associated with hearing loss (e.g., age at identification, communication skills) on how c...

BACKGROUND Hearing loss is the most common sensorineural deficiency in human beings. Cochlear implantation is introduced worldwide to treat the severe to profound sensorineural hearing loss, and can result in both speech comprehension and production. OBJECTIVES The present study aims to determine the effect of cochlear implantation on the improvement of the auditory performance in 2-7 years o...

BACKGROUND Hearing loss is the third most prevalent chronic condition faced by older adults and has been linked to difficulties in speech perception, activities of daily living, and social interaction. Recent studies have suggested a correlation between severity of hearing loss and an individual's cognitive function; however, a causative link has yet to be established. One intervention option f...

Cochlear implant systems translate acoustic information sampled from the acoustic environment into electrical impulses delivered directly to the patient’s auditory nervous system in an attempt to recreate functional hearing. After more than 30 years of intensive development, the efficacy of cochlear implants for the rehabilitation of severe to profound hearing loss has been well established, wi...

OBJECTIVE To monitor cochlear function by extra- and intra-cochlear electrocochleography (ECoG) during and after cochlear implantation and thereby to enhance the understanding of changes in cochlear function following cochlear implantation surgery. METHODS ECoG responses to acoustic stimuli of 250, 500 and 1,000 Hz were recorded in 9 cochlear implant recipients with presurgical residual heari...

Otosclerosis is a disease of the human otic capsule (1). Otosclerosis is well known to the otologist, as it is the most common cause for progressive conductive hearing loss in early adulthood. As hearing loss progresses, a sensorineural component is sometimes seen, resulting in a mixed hearing loss. In 1% of cases, the disease is considered purely cochlear, presenting with a sensorineural heari...

OBJECTIVE One of the most devastating sequelae of bacterial meningitis is profound hearing loss or even deafness. Although cochlear implantation is able to restore (some) hearing abilities, obliteration due to fibrosis and especially calcification of the cochlea in the postmeningitis period is limiting the success rate of an implantation. A national consensus assembled in a postmeningitis follo...

The protective effects of cochlear pre-conditioning have been documented, especially in regard to noise. Conditioning with moderate-intensity noise toughens the ear and makes it more resistant to damage from high-level noise exposures. The goal of the project was to determine whether cochlear pre-conditioning is effective in protecting against the ototoxic effects of cisplatin. Pre-conditioning...
