ABSTRACT

In clinical settings, hearing impairment is typically diagnosed using pure tone audiometry (PTA). By determining air conduction (AC) and bone conduction (BC) thresholds, the severity of hearing loss and the type of hearing loss for each ear can be documented. Nevertheless, the PTA outcomes can be questionable in some cases, in which the results from other tests are required to verify the hearing diagnosis. In this case report of a 32-year-old man diagnosed with a mild traumatic brain injury, the clinical usefulness of performing the audiometric Weber test for confirming the type of hearing loss is highlighted. Herein, PTA, tympanometry and tuning fork Rinne test yielded contradictory results, and the tuning fork Weber test was unsuccessful. As such, the incorporation of the audiometric Weber test into the routine audiological evaluation protocol can be beneficial to achieve an accurate hearing diagnosis.
