This document discusses effective communication with orthognathic patients regarding their diagnosis and treatment options. It is important to discuss the patient's case outside of their presence using clear language and involve the patient in discussions. Providing information through multiple methods like verbal, written and audiovisual aids can help patients better understand and retain information about their often complex treatment. Clinicians must clearly explain the patient's diagnosis, what may happen without treatment, and available treatment options with benefits and risks to gain informed consent.
