<prompt> A 38-year-old gentleman reports of decreased hearing in the right ear for the last 2 years. On testing with a 512-Hz tuning fork, the Rinnes test without masking is negative on the right ear and positive on the left ear. With the Webers test the tone is perceived louder in the left ear. The patient most likely has:Right conductive hearing lossRight sensorineural hearing lossLeft sensorineural hearing lossLeft conductive hearing loss  <response>: Negative Rinne on the right means bone conduction better than air conduction, meaning thereby conductive deafness. But this test has been done without masking the left ear which is normal in this case. Response to bone conduction could be from the left ear. Thus right ear suffers from sensorineural deafness. Rinnes test in this case is false negative.
