I work in publishing and attended a recent round table with various authors about this topic, most of what was brought up there has been already covered but theres one additional point I believe is worth raising.

When you start to break it down its very interesting how much of the language we use when characters express or act, even internally, assumes the presence of certain senses in any and all situations. To compellingly write someone who has been missing a sense for an extended period of time it often requires deconstructing even the way we would write something as simple as paying attention to someone in a conversation often relies on the use of words which are sight or hearing related. 

If a character can easily recall having that sense it might make sense that their internal monologue still words things the same way but particularly deaf authors (at least those at the talk I attended) have said its very easy to tell when an author is deaf themselves, or has at least done some amount of research, based on how much unwitting sensory terms or metaphors show up in writing. It can certainly be an interesting and thought provoking exercise when done well and with good intention.
