The tuning fork--an essential instrument in otologic practice.

P J Doyle, D W Anderson, S Pijl

The Journal of Otolaryngology

|April 1, 1984

Summary

The tuning fork remains a reliable tool for diagnosing conductive hearing loss and unilateral sensorineural hearing loss when used correctly. This study confirms its diagnostic value in audiology and otologic examinations.

Area of Science:

Audiology
Otology
Diagnostic Methods

Background:

The tuning fork is a traditional tool in audiology, though its utility is debated.
Misuse or lack of knowledge contributes to skepticism regarding its diagnostic capabilities.

Purpose of the Study:

To evaluate the diagnostic accuracy of tuning fork tests in identifying hearing loss.
To assess the tuning fork's effectiveness in diagnosing conductive and sensorineural hearing impairments.

Main Methods:

Tuning fork tests were administered to patients.
Results were correlated with comprehensive otologic examinations and audiometry.

Main Results:

Correctly used tuning forks accurately diagnose conductive hearing loss.
Tuning forks are invaluable for diagnosing unilateral total sensorineural hearing loss.
Frequency-specific tuning forks (256-1024 Hz) can estimate the degree of conductive loss.

Conclusions:

The tuning fork is a dependable diagnostic method when employed properly.
Understanding the method and limitations of tuning fork use is crucial for accurate diagnosis.
