Objective: Generated acoustic trauma by suction and drill may cause sensorineural hearing loss after Tympanomastoid surgery. This study was carried out to determine the relationship of sensorineural hearing loss and chronic otitis media surgery at Ahvaz Jundishapur University of Medical Sciences in Iran. Material and Methods: This prospective study included 386 patients of ch...
introduction: hearing impairment is the most frequent sensorial congenital defect in newborns and has increased to 2–4 cases per 1,000 live births. sensory-neural hearing loss (snhl) accounts for more than 90% of all hearing loss. this disorder is associated with other congenital disorders such as renal, skeletal, ocular, and cardiac disorders. given that congenital heart diseases are life-thre...
objectives: the aim of present study was evaluation of saccule function in cochlear implant candidates with severe to profound sensory neural hearing loss before and after cochlear implantation methods: in this study 35 cochlear implant (ci) candidates with bilateral severe to profound sensory neural hearing loss before and about 30 days after cochlear implant and 20 normal-hearing cases as a c...
Hearing loss and meningitis were correlate in some aspects. Hearing loss is the situation that can be shown in cochlear or retrocochlear defects. Cochlear hearing loss is caused by inner or outer hair cell damage (however cochlear hearing loss has another causes, such as defect of arterial spiral ganglion, basilar and tectorial membrane) and retrocochlear hearing loss has neural origin and meni...
Introduction: Some of the studies have shown that RA (Rheumatoid Arthritis) may cause hearing disorders. These disorders can result in problems later in life, so survey of correlation between rheumatoid arthritis and hearing disorders is important . Methods: This was a case-control study which has done from December 2004 to August 2006 at Shaheed Sadoughi hospital in Yazd. In this study, 50 R...
Background: Sudden Sensori-neural Hearing Loss (SSHL) is an abrupt failure of the cochlear function of unknown etiology. Possible causes include chronic infections leading to increased systemic levels of cytokines, which could damage the cochlear pumps H+, K+and Na+, K+ATPases. Helicobacter pylori infection stimulates systemic cytokine production. Proton pumps in cochlea and stomach are almost ...
Background: The objective of this study was to describe the audiologic and related characteristics of a group patient with speech perception affected out of proportion to pure tone hearing loss. A case series of patient were referred for evaluation and management to the Hearing Research Center.To describe the clinical picture of the patients with the key clinical feature of hearing loss for pur...
Sensori-neural hearing impaired listeners have difficulty in separating multiple signals or perceiving speech in background noise and hearing aids are widely used to enhance the desired signal. In this paper we present a simple two-input system to separate two signals using output decorrelation where the filter coefficients are adaptively estimated to minimise the correlation of the output sign...
OBJECTIVE A systematic review was conducted to identify and quality assess how studies published since 1999 have measured and reported the usage of hearing aids in older adults. The relationship between usage and other dimensions of hearing aid outcome, age and hearing loss are summarised. DATA SOURCES Articles were identified through systematic searches in PubMed/MEDLINE, The University of N...
