conclusions the assr can accurately predict the degree and configuration of hearing loss and discriminate the normal hearing from mild or moderate hearing loss and mild from moderate hearing loss, except for 500 hz. the air-conducted assr could not define the type of hearing loss. results the assr accurately estimates the behavioral thresholds as well as flat and sloping configurations. there w...

  Hearing loss is a major social problem and its rehabilitation is very important. Considering its prevalence in Iran, this study was performed to evaluate cases of hearing loss in referrals of Alzahra and Edgehie audiometry centers during the years 1995-1996. The descriptive strategy of this study was carried out on referrals of two audiometry clinics in Isfahan from October 1995 to 1996. Ou...

OBJECTIVE To assess the accuracy of threshold using the multiple auditory steady state responses (MASSR) to bone conduction stimuli in a group of patients with conductive hearing loss. METHOD Thirty patients with conductive hearing loss were assessed by MASSR and by pure-tone audiometry, and compared the results of these two methods. RESULT The thresholds of MASSR and those of PTA were sign...

otosclerosis is the most frequent cause of conductive hearing loss in patients with intact tympanic membrane. it can be treated by surgery with various techniques. because of limited manipulation and comparably similar results, stapedotomy at present is preferred over other surgical techniques by most surgeons. here we present the operative results of 114 otosclerotic patients who underwent sta...

One hundred three cases of skull fractures in or around the temporal bone were reviewed for hearing loss. Of these, 100 patients had skull series, 66 had computed tomographic head scans, and 44 had polytomographic studies of the temporal bone. Hearing loss in head trauma can be grouped into four categories: conductive hearing loss, peripheral sensorineural hearing loss, central sensorineural he...

Introduction: A common cause of conductive hearing loss in young children is otitis media, which when chronic or recurrent can effect speech and language development. However, little is known about the effects of such conductive loss on resting activity levels in the auditory system. Hypothesis: Conductive hearing loss will change spontaneous activity levels at the inner hair cell synapse, and ...

BACKGROUND Postoperative complications of myringotomy and tube placement often include otorrhea, tympanosclerosis, and tympanic membrane perforation. However, the incidence of sensorineural or conductive hearing loss has not been documented. Recent efforts to curb the use of preoperative audiometric testing requires documentation of this incidence. OBJECTIVE To define the incidence of conduct...

Malformations of bony inner ear are rare anomalies occurring in approximately 20% of patients with congenital sensorineural hearing loss. Conductive hearing loss is usually associated with abnormalities of the external and middle ear. Recent reports of patients with lateral semicircular canal malformations indicate inner ear malformations to be associated with sensorineural or conductive hearin...
