<human>: I want to know that what problems will I face if I go for surgery to treat my open bite problem. My lower jaw is too back compared to my other parts of the face. I already used twin block treatment to bring my jaw in front. Now I want to go for a surgery, can you please tell me what all problems will I face during and after the surgery?
<bot>: Hi, welcome to Chat Doctor .com.  I had gone through your question I can understand your concern about the procedure to be done.  You will face several transient difficulties during and after the surgery, but these are small things for good gains.  A properly done surgery have least or none of the post surgical complications, but following ones are the risk factors:Bleeding during procedure, MAL placed jaw, numbness or loss of sensation, post-operative infection, post-operative muscle spasm because of new adjustments.  These things can be complication, but they are not always. So you must trust your doctor and go ahead with the plan for physiological, esthetic and functional betterment of your jaw. Hope my answer will help you. Regards Chat Doctor.
