Ear, Nose and Throat Disorders Question
If a person, let's say teenage boy, gets in the car accident and gets a big head trauma which causes him to become deaf, can he talk anymore? Obviously, he loses his hearing but does the head trauma affect on his talking or other things? I know it's hard to answer this question without any details but I'm curious since I know that many can't talk at all if they are born deaf. Is there, for an example, a certain age when the talking becomes more harder if a person can't hear?
