Subject: Prevalence of single-sided deafness From: "Bernstein, Joshua G CIV NNMC" <Joshua.Bernstein@xxxxxxxx> Date: Mon, 9 Jul 2012 13:00:19 +0000 List-Archive:<http://lists.mcgill.ca/scripts/wa.exe?LIST=AUDITORY>------=_NextPart_000_0140_01CD5DB0.DDB58320 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit Dear List, I am trying to find data on the prevalence of single-sided deafness (SSD) in the general population (one severely-to-profoundly deaf and one normal/mild-to-moderately impaired ear). I find the statistic stated over and over again, without reference, that there are 60,000 new cases per year in the U.S. Multiplied by a 70-year lifespan, this would suggest 4 million individuals, or about 1% of the U.S. population, which seems high. The NIDCD website lists 4,000 cases/year for sudden sensorineural hearing loss, which overlaps with but does not equal the SSD population. Does anyone know where these numbers (4,000 or 60,000) come from, or know of a good reference for SSD prevalence data? The best I can find are studies on children that include less severe losses for the impaired ear. Thank you, Josh ________________________________ Joshua G.W.
