Orthognathic surgery is today a standard procedure for improving the intermaxillary relationship by moving either one or both jaws surgically. However, statistics for frequency and indication for orthognathic surgery in Sweden are today non-existent. The purpose of the study is to examine indications, frequency and surgical techniques for orthognathic surgery performed in Swedish Oral and Maxillofacial Surgery (OMFS) clinics.
A questionnaire survey was performed on all Swedish OMFS clinics for the year 2011 to identify gender and age of the patients, surgical techniques, indications, frequency of operations and whether patients underwent one- or two-jaw surgery. A total of 47 out of 50 clinics responded to the survey. According to it, 894 patients were treated with orthognathic surgery. Slightly more women underwent orthognathic surgery than men and 91% of the patients were 26 years or younger. The most common indication was functional and the most common main jaw discrepancy aimed to correct was of sagittal nature. The survey shows great discrepancies between the counties concerning one- vs. two-jaw surgery.
The results regarding frequency, age and gender distribution in orthognathic surgery was somewhat expected. However, the spread in frequency regarding one- vs. two-jaw surgery between the counties is concerning. The main indication for performing orthognathic surgery in Sweden is by far functional but there is reason to suggest that aesthetic indication is not negligible.
