Review of Anaesthetic Practice in Orthognathic Surgery

March 21, 2021 updated by: Singapore General Hospital

A Retrospective Review of Anaesthetic Practice and Intraoperative Blood Loss in Orthognathic Surgery in a Tertiary Hospital

Orthognathic surgeries for maxillofacial deformities are commonly performed globally. However, they are associated with significant blood loss which can affect the surgical field and result in blood transfusion and its risks. We aim to review the different hypotensive anaesthetic practices for orthognathic surgeries, and their effects on intraoperative blood loss and transfusion requirements.
