Background: Normal Eustachian tube function is one of the important factor required for successful tympanoplasty outcome. A clinically useful test for assessment of Eustachian tube function is still lacking. Aims And Objectives: To evaluate Eustachian tube function by impedance audiometry and compare the outcome of surgery with respect to graft take up in normal and abnormal Eustachian tube fun...

Cigarette smoking is a well known health problem affecting various body organs. There is a dearth of literature on early changes in auditory functioning at high frequency due to smoking. Hence, the present study aimed to investigate the audiological parameters for 100 chronic smokers. Their results were compared to 50 non smokers. Audiological test battery included conventional pure tone audiom...

INTRODUCTION Although tinnitus is an increasingly common symptom, few studies have assessed its prevalence or incidence among adolescents. PURPOSE To assess whether the presence of tinnitus in adolescents is associated with minimal hearing damage, evaluated through high-frequency audiometry (HFA), otoacoustic emission (OAE), and loudness discomfort level (LDL). METHODS The sample comprised ...

Introduction  The auditory system consists of sensory structures and central connections. The evaluation of the auditory pathway at a central level can be performed through behavioral and electrophysiological tests, because they are complementary to each other and provide important information about comprehension. Objective  To correlate the findings of speech brainstem-evoked response audiomet...

STUDY OBJECTIVE The aims were (1) to evaluate impedance measurements against pure tone audiometry as a screening method for the detection of middle ear changes associated with hearing loss in infant school children; (2) to estimate the costs of the health authority of each method. DESIGN The study involved two stage screening in which both methods were offered, pure tone audiometry being carr...

OBJECTIVES Five databases were mined to examine distributions of air-bone gaps obtained by automated and manual audiometry. Differences in distribution characteristics were examined for evidence of influences unrelated to the audibility of test signals. DESIGN The databases provided air- and bone-conduction thresholds that permitted examination of air-bone gap distributions that were free of ...

CONCLUSION These findings provide the basis for understanding the duration of the effect after the last use of the drug and encourage a larger clinical trial to collect additional evidence on the effect of coenzyme Q10 (CoQ10) in preventing the development of hearing loss in subjects with presbycusis. OBJECTIVES The aim of this study was to evaluate the long-term effects of a water-soluble fo...

OBJECTIVE To determine whether there is any influence of systemic arterial hypertension on the peripheral auditory system. METHODS This was a cross-sectional study that investigated 40 individuals between 30 and 50 years old, who were divided into groups with and without systemic arterial hypertension, using data from high-frequency audiometry, transient-evoked otoacoustic emissions and disto...

The flight crew of the Voyager aircraft were continuously exposed to a broadband noise for nearly 5 days during a trial flight, and for over 9 days during their nonstop flight around the world. Evaluation of the threshold shifts resulting from these exposures represents a unique opportunity to study the effect of human exposure to intense continuous noise for long durations. Postflight audiomet...
