Would really appreciate if anyone especially an audiologist or ENT can help explain this situation we’re in.
Our baby boy born Oct 12 this year, failed two hearing screening tests and was referred to an audiologist. The audiologist did the first test on Nov 27 and found he had profound conductive hearing loss at 95db on frequency 500 to 4000hz on the right ear but she seemed uncertain about the results and said she was going to get a second opinion. She concluded it was conductive because the bone conduction test was good. After doing research, I found conductive hearing loss can only be maximum at moderate level. I asked the audiologist and she agreed too that it was strange that it was in profound range and suspected maybe the earphone was loose during the test so she asked us to go in for a retest. So on dec 12, we went in for the retest. This time she concluded that it was profound sensorineural hearing loss. We were confused and asked why in the first test, the bone conductivity test was good and now it’s sensorineural loss. She said it could be because the assistant that helped held the equipment piece on baby’s head behind the ear placed it on the wrong spot so that the signals she got were actually muscle movements. (The second time the audiologist was the one who held the equipment piece on baby’s head.) we thought this was strange. Wouldn’t the assistant be experienced in this? How could they make a mistake like this? And how come audiologist seem so certain in first test that the bone conductivy result was good? Also, in the retest, baby hearing was 75db at 500hz, 85db at 1000hz, 95db at 2000hz, 105db at 4000hz. We are confused why the first test, it was 95db for all frequency and the second test was showing a gradual increase in loss the higher the frequency. Could someone please help explain these different findings? Thanks!
