A patient exhibits AC>BC on the Rinne test in both ears after Weber lateralizing to the right. What does this imply?

In this scenario, the Rinne test results showing air conduction (AC) greater than bone conduction (BC) in both ears typically indicate that there is no conductive hearing loss present; instead, it suggests normal hearing or a sensorineural hearing loss. The Weber test lateralizing to the right implies that the sound is perceived more strongly in the right ear.

In cases of unilateral sensorineural hearing loss, the sound will lateralize to the unaffected ear (the left ear in this case), while it will lateralize to the affected ear (the right ear here) in cases of conductive loss, due to different perception of sound vibrations. Since the Rinne test shows AC greater than BC, and the Weber test lateralizes to the right, it indicates that there is a sensorineural loss in the right ear.

Thus, the correct interpretation is that there is a right sensorineural loss.
