Orthognathic surgery can account for a considerable amount of blood loss since the vascularization of maxillofacial region is such that major bleeding can occur. Intra-bony bleed is often involved as a major aspect of blood loss associated with osteotomies, especially LeFort I osteotomy when performed during orthognathic surgery. This study evolved as a result of the increasing concern to attain a clear surgical field and reduce the duration of surgical procedure and the amount of blood loss associated with orthognathic surgery with the use of controlled hypotension.
