Pseudoaneurysms and Orthognathic Surgery: A Systematic Review and a Proposed Algorithm of Treatment.

This study aimed to gather existing evidence regarding the incidence, clinical presentation, and management of pseudoaneurysms (PA) after orthognathic surgery, identify the common blood vessels involved in PA, and propose a treatment algorithm based on current evidence. The protocol for this study was developed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analysis Protocols and was registered at the International Prospective Register of Systematic Reviews under the registration number CRD42020205479. Although these are rare, oral and maxillofacial surgeons should consider PA as a possible diagnosis, specifically in the maxillary artery of patients with epistaxis, severe facial edema, and swelling following LeFort I osteotomy.
