introduction: since middle ear surgery may lead to sensory neural hearing impairments, this study was carried out to evaluate the sensory neural hearing level after middle ear surgeries in kashani’s educational and therapeutic center, affiliated by isfahan university of medical sciences during 2002-4. materials and methods: this study was designed as a clinical trial. 90 cases with chronic otit...

background and aim: hearing impaired students experience binaural hearing like normal peers and school age is challenging time for using dichotic listening. lack of research was found on relationship of persian hearing impair­ed children with central auditory processing (cap). one of the aims of this study was a comparison between persian dichotic digit test (ddt) score in children with mild an...

introduction: children learn to communicate by hearing sounds. if there is hearing loss, the cognitive and speaking abilities and language learning will deteriorate. early detection and intervention are important factors in the successful treatment of hearing loss in children. hearing loss (hl) is divided into two main groups: conductive hearing loss (chl) and sensorineural hearing loss (snhl),...

Individuals with sensorineural hearing loss have difficulty understanding speech, especially in background noise. This deficit remains even when audibility is restored through amplification, suggesting that mechanisms beyond a reduction in peripheral sensitivity contribute to the perceptual difficulties associated with hearing loss. Given that normal-hearing musicians have enhanced auditory per...

multiple sclerosis (ms) is a demyelinating disorder of central nervous system. it involves 8th cranial nerve and its central nuclei and is an uncommon cause of the sensorineural hearing loss. for determining the prevalence of hearing loss (hl) especially retrocochlear type in ms, a cross-sectional study was designed using pure-tone audiometry (pta), otoacustic emissions (oaes), auditory brainst...

background: taxi drivers have the most important role in the public transport services. they are exposed to various harmful agents and occupational hazards. noise is a harmful occupational factors and hearing loss is its most important effect. protection of drivers against hearing loss is essential. this study was performed to determine the prevalence of hearing loss among taxi and agency drive...
