What are the possible difficulties presented by people who have suffered facial trauma?

Chewing and swallowing are the functions more impaired, because facial trauma is mainly comprised of damage to the facial muscles, teeth and bones of the maxilla and mandible. Thus, a change occurs in speech articulation and also in the opening and closing of the mouth during speech and chewing. The TMJ and the aesthetics of the face may also be impaired. Speech is in the domain of a Speech-Language Pathologist.
