Question
I have a severe to profound loss and ear canal atresia. An audiologist recommended a BTE aid with an in the ear piece that holds the microphone. Are you familiar with this type of aid? Thanks. Janet

Answer
Hi Janet,
"BTE" is the generic term for any hearing aid where the body of the aid is "behind the ear."  The specific type of BTE that your audiologist is recommending is known as a "receiver in the ear" or RIC for short.  This particular BTE has a very thin tube that enters the ear canal as opposed to the thicker and more bulkier tubes and earmolds. And, instead of the receiver - the part of the aid that delivers sound into the ear - being part of the actual hearing aid, it is actually attached to the end of the ear tube that goes into the ear.  They are a definite option for persons with canal atresia.  However, there are a couple of drawbacks.  Because the receiver itself goes into the ear, they are very prone to wax and debris buildup from the canal and often need to be cleaned or replaced.  Another is the possibility of feedback - that high pitched whistling sound, especially with higher gain. But that too can easily be managed with a special type of mold that can be used even in cases of atresia. The best thing to do is to work with your audiologist on this to obtain the optimum fitting.

Hope this helps.
