Research Abstract

1. Surgical changes in soft tissue profile after Le Fort I type osteotomy were cephalometrically evaluated in patients with minimum 1 year follow-up. Nasal angle and nasal height were reduced in their values because of larger amount of advancement of Sn than that of Prn. By maxillary anterior segmental osteotomy, nasal height was not reduced and Sn was remarkably brought anteriorly in comparison with posterior movement of Prn which could be nearly disregarded.
2. Surgical changes of gonial angle and ramus inclination were cephalometrically evaluated in 45 patients with mandibular prognathism. The gonial angle and ramus in clination were improved with the mean values of 4.3 and 4.5 degree respectively. These results showed that the sagittal splitting osteotomy of the mandibular ramus plays great role in improvement of the obtuse gonial angle in the patient with mandibular prognathism. A new technique for two- and three-dimensional prediction of soft and hard tissue contour was developed using plaster cast of the mandubular dental arch, occlusal splint and computer graphic system.
3. A questionnare study was made in 178 patients with mandibular deformities operated by sagittal splitting osteotomy, anterior segmental osteotomy and genioplasty for evaluation on masticatory function, sensory disturbance of the lower lip and temporomandibular joint function. 80.2% of the patients was satisfied in masticatory function and sensory disturbance was disappeared in 50% of the patients within 1 year postoperatively. 37.9% of the patients operated by sagittal splitting osteotomy complained of the disturbance in 2 years postoperatively. The joint pain at jaw movement was observed in 38.7% of the patients by the osterotomy immediately after releasing intermaxillary fixation and disappeared completely in all of the poerated cases after 3 years postoperatively.
