sensorineural non-syndromic hearing loss is the most common disorder which affects 1 in 500 newborns. hearing loss is an extremely heterogeneous defect with more than 100 loci identified to date. according to the studies, mutations in gjb2 are estimated to be involved in 50- 80% of autosomal recessive non-syndromic hearing loss cases, but contribution of other loci in this disorder is yet ambig...

Background: Our research focuses on different dimensions of families of Turkmen population of Iran with two or more than two affected members. A complete clinical ear test was conducted on them. It was aimed to find families with the highest chance of hereditary hearing impairment among siblings and also existence of consanguinity among their parents. <em...

Hearing loss affects approximately one-third of adults 61 to 70 years of age and more than 80 percent of those older than 85 years. Men usually experience greater hearing loss and have earlier onset compared with women. The most common type is age-related hearing loss; however, many conditions can interfere with the conduction of sound vibrations to the inner ear and their conversion to electri...

this randomized clinical trial aimed to assess the efficacy of phlebotomy on improvement of hearing loss. 71 patients with sudden sensorineural hearing loss were enrolled in this randomized clinical trial study. they were divided into two groups: group a received steroid and hydration therapy plus phlebotomy, while group b received the same regimen without phlebotomy. they were matched accordin...

PURPOSE Previous studies of connexin-related hearing loss have typically reported on mixed age groups or adults. To further address epidemiology and natural history of connexin-related hearing loss, we conducted a longitudinal study in an ethnically diverse cohort of infants and toddlers under 3 years of age. Our study compares infants with and without connexin-related hearing loss to examine d...

BACKGROUND Hearing Preservation is becoming increasingly important in cochlear implantation as there is growing evidence that preserving the residual hearing, especially in the low frequencies in combination with the electric stimulation can significantly improve hearing and speech outcomes in noise. Besides the ongoing development of atraumatic implant electrodes and insertion techniques, the ...

Hearing-impaired listeners with similar hearing losses may differ widely in their ability to understand speech in noise. Such individual susceptibility to noise may explain why patients obtain varying degrees of benefit from hearing aids. The chief purpose of this study was to determine if adaptive measures of unaided speech recognition in noise were related to hearing aid benefit. Additionally...
