Orthognathic surgery is safe and reliable surgery, but in rare cases there may be some complications that can be disastrous and even sometimes fatal. In this study, we aim to analyze the different types of complications in orthodontic surgeries. This study is a retrospective investigation of the records of 12 patients who underwent orthognathic surgery between 2015 and 2016 in the Department of Oral and Maxillofacial Surgery at Ain Shams University, Cairo, Egypt. The types of complications were documented, and separate surgical factors were recorded and evaluated.
A number of complications have been identified, such as poor bite of teeth after surgery, morbidity or nerve pain, failure of plates and screws and relapse. We found that more complications were present in the time consuming surgeries. In summary, postoperative malocclusion, bad split and infection are the most common complications in orthodontic surgeries.
