The mandibular contour determines the shape of the lower part of face and thus influences the appearance of head and neck. A prominent mandibular angle produce characteristic quadriangular, coarse and muscular appearance. To correct this facial contour to oval shape, the prominent angle can be contoured. 
 The cutaneous approach has been used, but it leaves noticeble scar and has risk of facial nerve injury. Thus the intraoral approach has been used commonly. But because of restriction of operation field, the intraoral approach has disadvantages of long operation time, high risk of complications.
 So, we have performed mandibular contouring procedure by new approach which uses reciprocating saw through stab incision under the mandibualr body to correct the 9 patients of mandibular angle protrusion who visited our clinics recently.
 And we found that mandibular angle contouring by this new approach is easy, and makes the operation and recovery time shorter. There were no complications and cosmetic results were quite satisfactory.
