Objectives:

Orthognathic surgery has undergone a significant development in recent years becoming a safe surgical technique. However, different complications can occur after orthognathic surgery. The purpose of this study is to analyze the possible complications found during surgery and immediately after orthognatic surgery, at our institution.

Material and methods:

A retrospective descriptive study comprising 284 consecutive orthognathic surgical procedures performed between January 1, 2000 and December 31, 2016 at Povisa Hospital, Vigo, Spain, were studied.

Results:

Mean age of the treated patients was 28.72 years. 64.4 % were women. The most frequent dentofacial deformity diagnosed was Angle class III malocclusion and the most frequent performed osteotomy was Le Fort I maxillary osteotomy. The majority of patients were classified as ASA I. Mean operative time was 174 minutes and mean hospitalization time was 3.26 days. Postoperative nausea or vomiting (PONV) was the most frequent complication found. Statistically significant correlations were found between the type of osteotomy performed and postoperative bleeding, PONV, anxiety, need of blood transfusion and postoperative pain.

Conclusions:

The low rate of complications found in the present study suggests that orthognathic surgery is a safe surgical procedure.
