title: [Unfavorable effects induced by mandibular surgery in Class II malocclusions].
abstract: The sagittal split ramus osteotomy is probably the most frequently used procedure for correction of mandibular skeletal dento-facial deformities. In the 30 years since the procedure was introduced, a number of complications has been reported: unfavorable fracture during surgery, paresthesia or anesthesia and relapse. The literature seems to be very poor concerning the esthetical and morphological complications of the sagittal split ramus osteotomy; especially when treating Class II dento-facial deformity frequently associated with a genioplasty. The purpose of this study was to determine and analyze the esthetical complications occurring after mandibular surgery in patients with Class II dento-facial deformities: Pre-angular notches, Widening of the bi-angular distance, The unaesthetic effects of the associated genioplasty, Class III like "dento-facial deformities", Plates and screws visibility. Each of those complications has been analyzed to find a preventive treatment.
