The authors used high-resolution computed tomography (HRCT) for studying 52 congenitally malformed ears in 45 children between five and 10 years of age. In six children the malformations were bilateral. The malformations clinically manifested as microtia, atresia of the external auditory canal and conductive deafness. Analyzing anatomical details and pathological changes on HRCT axial sec...

abstract background: the aim of this study was to determine the auditory performance of congenitally deaf children and the effect of cochlear implantation (ci) on speech intelligibility. methods: aprospective study was undertaken on 47 children in a pediatric tertiary referral center for ci. all children were deaf prelingually and were younger than 8 years of age. they were followed up until 5 ...

background and aim: research shows that 13-18 percent of the people suffer from tinnitus, almost 5 percent of which, have chronic or bothersome tinnitus. chronic tinnitus may be accompanied by anxiety, depression, insomnia, and impairment in cognitive functions such as memory and attention. the purpose of this study was to compare the verbal auditory memory and divided attention between individ...

background and aim: respiratory distress syndrome (rds) is a lung disorder, which can damage the auditory brainstem pathways because of hypoxia. the aim of this study was to evaluate brainstem auditory electrophysiology changes of neonates with rds. methods: fifteen term neonates who suffered from rds, 15 term neonates admitted in the nicu for any reason except rds, and 15 normal term neonates ...

Event-related Potentials (ERPs) were recorded to both tuditory and visual stimuli from the scalps of nine autistic males and4re normal, ) controls to examine the differences in information processing strategies. ( Subjects were tested on three different tasks (in the following order): 1) an auditory missing stimulus paradigm; 2) a visual color.dischriminition; 'and 3) an auditory tone discrimin...

background and aim: although recent research has revealed the positive effects of bilin­gualism on children's cognitive abilities, little information is available on the relationship bet­ween bilingualism and working memory. working memory is generally composed of four dis­tinct parts, among which the phonological loop plays an important role in speech and language development, reading skills, ...

in an attempt to assess objectively the integrity of the auditory pathways in 30 patients with definite multiple sclerosis (ms), an audiometric evaluation was performed and auditory brainstem responses (abrs) were obtained. stressing the auditory system by increasing the stimulation rate showed some enhancement in the identification of ms. 24 (ro%) patients had an abnormal abr along with clinic...

introduction: first branchial cleft anomalies manifest with duplication of the external auditory canal.   case report: this report features a rare case of microtia and congenital middle ear and canal cholesteatoma with first branchial fistula. external auditory canal stenosis was complicated by middle ear and external canal cholesteatoma, but branchial fistula, opening in the zygomatic root and...

Recent studies have shown that mutations in PTPRQ, a gene encoding a receptor-like inositol lipid phosphatase, cause recessive, nonsyndromic, hereditary hearing loss with associated vestibular dysfunction. Although null mutations in Ptprq cause the loss of high-frequency auditory hair cells and deafness in mice, a loss of vestibular hair cells and overt behavioral defects characteristic of vest...
