In clinical settings, air conduction (AC) thresholds of pure tone audiometry (PTA) represent the severity of hearing loss. If the AC thresholds are within the normal limit (≤20 dB HL), bone conduction (BC) thresholds are not typically determined. In this case report, the importance of having BC thresholds is highlighted (even though AC thresholds are normal) to achieve an accurate diagnosis.
