Most patients who require orthognathic surgery are young patients of American Society of Anesthesiologists’ (ASA) grade I, and current publications recommend a policy of group and save, with antibody screening for all such patients. We retrospectively studied 284 patients who had orthognathic procedures over a 5-year period at one hospital. We identified patients with a history of bleeding disorders, and those with abnormal coagulation. No blood transfusions were required for any patient, and abnormal coagulation screens in patients with no history of bleeding disorders made no difference to perioperative medical or surgical management. We therefore recommend that grouping and saving blood with antibody or coagulation screening are not necessary before orthognathic operations in ASA grade I patients who have no history of bleeding disorders or previous blood transfusion. However, a routine full blood count should still be done, in keeping with the current National Institute for Clinical Excellence (NICE) guidelines.
