It depends. Many deaf parents want the best for their kids; if it means giving them all the opportunities the other kids have they may allow it to happen. There are some pretty good documentaries on this issue, ex: Sound and Fury. I think being deaf may violate the technical standards -
[Passage from __ MD School technical standard policy]
Communication:
Candidate/student must be able to hear, observe and speak to patients
in order to elicit and acquire information, examine them, describe changes in mood,
activity, and posture, and perceive their nonverbal communication. Students must also be
able to communicate effectively in oral and written form with staff and faculty members,
the patient, and all members of the health care team.
