Although sensorineural hearing loss (SNHL) is known to compromise central auditory structure and function, the impact of milder forms of hearing loss on cellular neurophysiology remains mostly undefined. We induced conductive hearing loss (CHL) in developing gerbils, reared the animals for 8-13 d, and subsequently assessed the temporal features of auditory cortex layer 2/3 pyramidal neurons in ...

The major consequence of sensorineural hearing loss (SNHL) is communicative difficulty, especially with the addition of noise and/or reverberation. The purpose of this investigation was to compare two types of technologies that have been shown to improve the speech-perception performance of individuals with SNHL: directional microphones and frequency modulation (FM) systems. Forty-six adult sub...

However, it is important to remember that modern adaptive directional and adaptive noise reduction features are criterion based; the input signal must have certain characteristics for these systems to activate.In contrast, compression is a "24/7" function in hearing aids all signals pass through the compression system. Multi-channel, non-linear (MCNL) amplification is widely considered to be th...

Introduction: Inflammatory bowel disease (IBD) is a chronic, idiopathic, relapsing, inflammatory of the gastrointestinal system, which includes two different diseases, namely ulcerative colitis (UC), and Crohn's (CD). Inner ear involvement IBD, causes sensorineural hearing loss (SNHL) acute bilateral arises in short period weeks to months active disease.
 Methods: The present study include...

CONCLUSIONS Congenital cytomegalovirus (CMV) infection is a major cause of bilateral and unilateral sensorineural hearing loss (SNHL) in children, accounting for 9.0% of SNHL cases. The diagnostic rate using combined genetic deafness test and CMV DNA detection test was determined to be 46.4% in bilateral profound SNHL. OBJECTIVES The present study investigated the prevalence of congenital CMV...

Introduction: The aim of this study was to evaluate the width bony cochlear nerve canal (BCNC) in children with congenital sensorineural hearing loss (SNHL) and "normal" findings on thin section temporal bone CT. Material methods: BCNC retrospectively evaluated two groups patients. group included 11 (22 canals) aged 2-12 years, congenital, bilateral SNHL who underwent implantation (CI) from Jul...

Background: Hearing impairment, as one of the most common birth defects, is a hidden disability with negative impacts on speech and cognitive development. Objectives: The aim of this study was to assess the prevalence of sensorineural hearing loss (SNHL) and determine the associated risk factors among infants admitted to neonatal intensive care units (NICUs) and neonatal wards of teaching hospi...

Large Vestibular Aqueduct Syndrome (LVAS) is the most common radiographic malformation in children with early onset of hearing loss. Usually its occurrence is non-familial, however intriguingly a portion of patients with LVAS is found to have evidence of genetic predisposition. We described cases of LVAS in two siblings of a Chinese family. The elder sister first presented with reduced hearing ...

BACKGROUND Dilated cardiomyopathy (DCM) and sensorineural hearing loss (SNHL) are prevalent disorders that occur alone or as components of complex multisystem syndromes. Multiple genetic loci have been identified that, when mutated, cause DCM or SNHL. However, the isolated coinheritance of these phenotypes has not been previously recognized. METHODS AND RESULTS Clinical evaluations of 2 kindr...

Objective: Unusual clinical course Background: The classical picture of giant cell (temporal) arteritis (GCA) is not always evident. A wide variety of unusual presentations have been increasingly reported. Sensorineural hearing loss (SNHL) as an initial manifestation of GCA is a rare, yet important entity. Similar to blindness, SNHL also deserves serious attention as timely intervention may pla...
