금속 가이드 장치를 이용한 하악골 골절제술

Abstract

Intraoral approach for mandible angle contouring has been popularized because it can avid external scars on the face. However it is difficult to perform safe and precise as condylar fracture, asymmetry, undercorrection, and overcorrection. Among these complications, the main reason of condyle fracture and asymmetry may be caused by the wrong perception of the pathway of osteotomy. To be free form such wrong perception of the osteotomy pathway, we designed guiding instrument for osteotomy of the mandible angle and used this guiding instrument in 14 patients successfully.
