Objective: Several patients and operator related factors have been confirmed to be of importance for blood loss in orthognathic surgery, e.g., type of surgical intervention and operative time. However, the surgeon's impact has been studied only to a limited extent. Thus, the primary aim of this study was to evaluate the surgeon's impact on intraoperative blood loss. Methods: Clinical data was gathered retrospectively for all osteotomies performed by three different experienced surgeons between January 1st, 2013 to December 31st, 2016 at a regional centre for orthognathic surgery at the Sahlgrenska University Hospital, Gothenburg, Sweden. Results: A total of 179 patients (92 women and 87 men) who underwent Le Fort I osteotomy, Bilateral Sagittal Split osteotomy, or Bi-maxillary osteotomy were included. No statistically significant difference was seen between the three surgeons for intraoperative blood loss. Conclusion: Intraoperative blood loss during orthognathic surgery is not operator dependent when experienced surgeons are compared.
