Furthermore, to study whether the effects of OM on adult hearing thresholds are moderated by age or noise exposure.

To study the extent to which otitis media (OM) in childhood is associated with adult hearing thresholds. Clinicians should remain mindful of these differences and optimize these techniques in specific clinical applications to improve TFT accuracy. Variability exists in the reported test accuracy measurements of TFTs for clinical screening, surgical candidacy assessments, and estimation of hearing loss severity. There is high risk of bias in patient selection for a majority of the studies. Significant heterogeneity in TFT methods and audiometric thresholds to define hearing loss precluded meta-analysis. The audiometric thresholds at which tests transition from normal to abnormal ranged from 13 to 40 dB of conductive hearing loss for the Rinne test and from 2.5 to 4 dB of asymmetry for the Weber test. The sensitivity and specificity of the Rinne test for detecting conductive hearing loss ranged from 43% to 91% and 50% to 100%, respectively, for a 256-Hz fork and from 16% to 87% and 55% to 100% for a 512-Hz fork. Seventeen studies with 3158 participants, including adults and children, met inclusion criteria. Two independent evaluators corroborated the extracted data and assessed risk of bias.

PubMed, Ovid Medline, EMBASE, Web of Science, Cochrane, and Scopus and manual bibliographic searches.Ī systematic review of studies reporting TFT accuracy was performed according to a standardized protocol. (2) To identify the audiometric threshold at which TFTs transition from normal to abnormal, thus indicating the presence of hearing loss. (1) To determine the diagnostic accuracy of tuning fork tests (TFTs Weber and Rinne) for assessment of hearing loss as compared with standard audiometry. 83 patients were negative to 256 Hz tuning fork but positive to 5 Hz tuning forks had the air-bone gap range of 20 to 29 dB with a mean air-bone gap of 25.46 dB.Ĭ onclusions: We conclude that Rinne’s tuning fork test can be used to quantify the degree of conductive hearing loss into mild (20-30 dB), moderate (30-45 dB), and severe (45-60 dB).

Background: The Rinne tuning fork test is used routinely in clinical ENT examination. To view the remaining sections of this topic, please log in or purchase a subscription.

Weber Test: Same tone loudness heard equally in both ears.Ĭritical Findings and Potential Interventions.

Schwabach Test: Same tone loudness heard equally long by the examiner and the patient.

Rinne Test: Longer and louder tone heard by air conduction than by bone conduction ( Note: This result, observed in patients with normal hearing, is also observed in patients with sensorineural hearing loss.).

Bing Test: Pulsating sound that gets louder and softer when the opening to the ear canal is alternately opened and closed ( Note: This result, observed in patients with normal hearing, is also observed in patients with sensorineural hearing loss.).

Normal air and bone conduction in both ears no evidence of hearing loss.

There are no food, fluid, activity, or medication restrictions unless by medical direction.

To assess for and determine type of hearing loss.
