UNFAVORABLE RESULTS AND THEIR RESOLUTION IN MANDIBULAR CONTOURING SURGERY

Since the development of mandibular contouring surgery, there have bee n many unfavorable results due to technical reasons. Those results inc lude asymmetry, undercorrection, overcorrection, and an incorrect cont our line. Over three years the authors have analyzed 19 cases of unfav ourable results and found the following: (1) There have been 7 cases o f undercorrection, 5 cases of asymmetry, 5 cases of incorrect contour line, and 2 cases of overcorrection. (2) The main technical errors tha t cause unfavorable results seem to be the simple straight cutting of mandible angles instead of curved cutting using multistaged curved ost ectomy. (3) We suggest that the basic way to prevent unfavorable resul ts in mandibular contouring surgery is to contour the mandible, includ ing angle, body, and symphysis, as a whole by way of multistaged curve d ostectomy.
