As Westernization has taken place in the Oriental society, people's concern focuses on the correction of their lower jaw shape. Various methods were recommended to make their mandibular angle slender and beautiful, but it was difficult to achieve natural curves as planned preoperatively. This study was conducted on 6 patients who received burring hole connecting osteotomy for mandibular angle correction from 2005 to 2007. A measurement of the most natural curved line for osteotomy was made by X-ray prior to the surgery. Through intraoral approach, three to five holes were made on the estimated angle line by burring, and the consecutive holes were connected by oscillating saw to perform the one piece osteotomy. There were no unnatural, irregular osteotomy sections or asymmetrical problems in comparison of before and after operation. All of the patients had satisfactory natural mandibular angle lines. Despite difficulties with the conventional techniques, it is possible for patients to achieve natural mandibular angle lines as they wish with the burring hole connecting osteotomy technique. In addition, it was possible to secure outstanding predictability and stability, thus resulting in satisfactory outcomes in the profile.
