INTRODUCTION Despite advances in imaging and other diagnostic tests, it is often impossible to establish with confidence a pre-operative diagnosis in a patient with a conductive hearing loss. METHODS We studied a series of 340 exploratory tympanotomies for conductive hearing loss carried out by a single surgeon. RESULTS The most common operative diagnosis was otosclerosis (n = 164, 48.2 per...

introduction: occupational exposure to excessive noise is commonly encountered in a large number of industries in iran. this study evaluated the hearing threshold and hearing loss in meybod tile factory workers. methods: this cross-sectional study included 371 tile factoryworkers during summer and autumn of 2005. current noise exposure was estimated using sound level meter .a specially formatte...

OBJECTIVE To determine the frequency and causes of hearing impairment in patients attending the out patient department of Civil Hospital Karachi. METHODS This study was carried out at the ENT department of Civil Hospital Karachi from January 1998 to October 2000. Six hundred patients were randomly selected from the out patient department. Patients of all age groups and both genders were inclu...

BACKGROUND Little research exists to demonstrate efficacy and verification measures of the Baha system versus traditional bone-conduction hearing aids. This study gives statistical data about 10 children who have used traditional bone-conduction hearing aids, Baha coupled to a Softband, and the Baha system implanted. PURPOSE The purpose of this study was to compare functional gain at 500, 100...

OBJECTIVES/HYPOTHESIS To evaluate modified coupling techniques of the Vibrant Soundbridge system in patients with mixed and conductive hearing loss and to compare it with conventional vibroplasty. STUDY DESIGN Retrospective study. METHODS Two different groups were evaluated: 1) nine cases of conventional incus vibroplasty in comparison with 2) nine patients with modified coupling of the flo...

OBJECTIVES The purpose of this study was to give a brief review of the effectiveness of otoacoustic emissions for getting frequency-specific information about a hearing-loss problem in newborns after hearing screening. Especially, the advantages of distortion-product otoacoustic emissions (DPOAE) over transiently evoked otoacoustic emissions (TEOAEs) are described. DATA SOURCES Approximately ...
