^ It sounds to me that the scene would have been similar in purpose to the scene in Voyage Home when McCoy cures the old ladies kidney issues with the punch line being the guy will be fine in 2 minutes
It sounds like a cute scene that I think they could have done without fancy FX. That being said as it is an unnecessary scene I can see why it was cut.
Of course, it wasn't essential to the movie, but in a movie that is loaded with a lot of pure crap--it actually could have been decent and replaced something that wasn't!
Anyway, perhaps someday we'll get a chance to see for ourselves.
