Exposure to excessive noise level is capable of producing destruction of the hair cells due to vasoconstriction of the cochlea blood vessels and over stimulation of the hair cells as a response to the noise exposure, which in turn may reduce the nutrient and oxygen to the cells as well as, placing a great impingement on the occupational performances of the Industrial workers. The study examined...

Background: hearing evaluation in children. Aim: to verify the Minimum Response Levels (MRL) through the use of Visual Reinforcement Audiometry (VRA) in the sound field, in 50 normal hearing children and in 25 children with hearing loss, taking into account the following variables: side of sound presentation, gender, age and type of stimulus. Method: VRA was performed using pure tone frequency ...

OBJECTIVES Temporomandibular joint disorders (TMD) are often associated with aural manifestations. However, it is not clear whether aural fullness could be induced by TMD. The purpose was to investigate the TMD and effectiveness of TMD treatments in patients with mainly or exclusively aural fullness complaint. METHODS One hundred and twelve patients, who had aural fullness as the main or sole...

CONTEXT Hearing loss is the third most prevalent chronic condition in older adults and has important effects on their physical and mental health. Despite these effects, most older patients are not assessed or treated for hearing loss. OBJECTIVE To review the evidence on screening and management of hearing loss of older adults in the primary care setting. DATA SOURCES AND STUDY SELECTION We ...

INTRODUCTION Previous reports indicated that middle ear surgery might partially improve tinnitus after surgery. However, until now, no influencing factor has been determined for tinnitus outcome after middle ear surgery. OBJECTIVE The purpose of this study was to investigate the association between preoperative air-bone gap and tinnitus outcome after tympanoplasty type I. METHODS Seventy-fi...

This study was aimed to sequentially document the patient's audiological improvement after stapedotomy as measured by pure tone audiometry. This prospective clinical study was performed in a total of 112 patients (age range: 20 63 years), diagnosed with Otosclerosis who underwent Stapedotomy at the Department of Otology, Madras ENT Research Foundation, Chennai between September 2010 to March 20...

BACKGROUND Potential methods of application of self-administered Web-based pure-tone audiometry conducted at home on a PC with a sound card and ordinary headphones depend on the value of measurement error in such tests. OBJECTIVE The aim of this research was to determine the measurement error of the hearing threshold determined in the way described above and to identify and analyze factors in...

BACKGROUND It is recognized that the size of tympanic membrane perforation is proportional to the magnitude of hearing loss, however, there is no clear consensus on the effect of the location (site) of the perforation on the hearing loss. Hence the study is set to investigate the relationship between the location of perforation on TM and hearing loss. METHODS A cross-sectional prospective stu...

Renal failure result in accumulation of nitrogenous waste in the body it is reversible in acute renal failure and irreversible deterioration of renal function leading to progressive destruction of nephrons in chronic renal failure (CRF). There is uremia, hyponatremia, hypertension and fluid retention in CRF causes direct and indirect effect on the inner ear including audiovestibular apparatus. ...
