Most in-the-ear hearing aids - and that includes TransEar's transfer unit - are affected by the temporal-mandibular joint, because movement can change the shape of the ear canal. As with most things anatomical, each of us has our own characteristics, and some have a very small joint while others have a whopper. When we receive an ear impression for TransEar, we can easily see the size of the TMJ, but large joints will rarely affect our ability to fit the new smaller TransEar270 that a few members have. Those with TMD, a disorder that allows for irregular movement of the joint, are not necessarily restricted from using TransEar, but there is an added fear that the irregular movement might occlude the ear canal. With the transfer unit in the ear, that might cause pain. We do not know if a TMD sufferer is using our product, so I am not willing to make a categorical statement of use, except to say that the TMD sufferer will need to work extra closely with the dispensing professional on getting the proper fit, one that includes any irregular sizing of the ear canal.
I am trying to get to the Philly symposium in July, with an eye to getting the medical profession up-to-speed on TransEar quicker. Meeting some forum members, with or without TransEar, would be an added treat.
