Hey, Jeff. Sounds kind of wierd until you connect this case with the new
studies coming out about the long term effects of monaural hearing
aid use. I'm sorry, I don't have the citations, as I am at home, not the
office, but it seems to me that in HI or HR or maybe E&H there have been some
 studies reported that many people over a long enough span, begin to lose the
ability for binaural fusion. Apparently the neural connections in the inferior
colliculus, or wherever, lose their common connection. This might explain your
patients dilemma, she has no sense of binaural fusion.
Whatta ya think?
