Effect of Induced Hypotensive Anesthesia and Normotensive Anesthesia on Intraoperative Blood Loss During Orthognathic Surgery: A Systematic Review.

Background: Orthognathic surgery involves significant bleeding from both soft tissues and bones due to rich blood supply to areas involved. In addition, limited access along with poor visibility and difficulty to isolate or ligate adds to the problem of bleeding during surgery. As a result, to counter drawbacks of intraoperative bleeding, method of induced hypotension stands out.

Donor Site Morbidity in Patients Undergoing Maxillofacial Reconstruction Using Free Fibula Flap Versus Deep Circumflex Artery Flap-A Systematic Review.

Introduction: A systematic review of the literature on the donor site morbidity in patients undergoing Maxillofacial reconstruction was performed. The two widely used flaps namely free fibula flap (FFF) and DCIA flap were compared to answer the following questions: (1) Is donor site morbidity significantly different in patients undergoing maxillofacial reconstruction with FFF and DCIA flap? (2) Should donor site morbidity be considered as the criteria for choosing the flap for reconstruction.

Materials And Methods: The search strategy was based on PRISMA guidelines.
