Le Fort I Osteotomy and Posterior Maxillary Segmental Osteotomy for Correction of Malunioned Maxilla.: Hui Dae Park, Yun Ho Bae, Jae Hyun Park, Myeong Jin Lee, Byung Rho Chin, Hee Keung Lee; Yeungnam Univ J Med. 1990;7(1):203-210.

Abstract PDF: This is a case report of correction of malunioned maxilla after traffic accident by Le Fort I osteotomy and posterior segmental osteotomy. By this procedure, authors obtained the following results. 1. The malunioned maxilla after traffic accident which had anterior crossbite, posterior open bite and scissor's bite were corrected by Le Fort 1 osteotomy and posterior segmental osteotomy. 2. No postoperative infection and specific complication were seen in this case. 3. Postoperative intermaxillary fixation was maintained for 8 weeks. And then, the patient could open his mouth in normal range after a week of intermaxillary fixation removal. 4. For rigid fixation and reducing relapse, the osteotomized maxilla was fixed with miniplates.

A Case Report of Correction of Mandibular Prognathism by Intraoral Oblique Splitting Osteotomy of Mandibular Rami.: Hui Dae Park, Kee Young Doe, Yun Ho Bae, Sang Kill Byun, Byung Rho Chin, Hee Keung Lee; Yeungnam Univ J Med. 1989;6(2):183-194. Published online December 31, 1989; DOI: https://doi.org/10.12701/yujm.1989.6.2.183

Abstract PDF: This is a report of 2-cases of mandibular prognathism corrected by Intraoral oblique splitting osteotomy of mandibular rami. The Intraoral oblique splitting osteotomy is a modification of sagittal split osteotomy of ramus and it is documented by Yoshida, on 1985. By this method, authors obtained the following results. 1. The patients' esthetic, psychological and functional problems were dissolved by setback of mandibular prognathism. 2. The postoperative infection splitted bone segments fracture, paresthesia of the face and T.M.J. dysfunction were not appeared. 3. Postoperative intermaxillary fixation was maintained for 8 weeks. The patients could open their mouths in normal range after a week of intermaxillary fixation removal. 4. The soft tissue changes of lower lip and chin were about 1:1 to the hard tissue changes. 5. During intermaxillary fixation period and postoperative orthodontic treatment, slight relapse was observed. Now, the patients are under postoperative orthodontic treatment.

Surgical-Orthodonic Correction of Adult Bimaxillary Protrusion: Report of 2 cases.: Hee Kyeung Lee, Byung Rho Jin, Jong Won Kim, Jeung Mee Lee, Kee Yong Do, Hui Dae Park; Yeungnam Univ J Med. 1988;5(1):127-133. Published online June 30, 1988; DOI: https://doi.org/10.12701/yujm.1988.5.1.127

Abstract PDF: Two patients, sought treatment for chief complaints of protruding frontal tooth and desired treatment to reduce the prominence of lips, were diagnosed as bimaxillary protrusion via clinical and cephalometric analysis. The authors corrected them by combined surgical and orthodontic treatment. As pre-surgical survey, paper and cast surgery were performed and wafer and resin sprint were constructed. We performed anterior maxillary and mandibular osteotomies in first premolar site to retract the maxillary and mandibular dentoalveolar segment in order to; 1) Decrease prominence of upper and lower lips. 2) Create proper lower incisor intrusion. By use of intramaxillary fixation, prompt oral intake was possible. We made good result of esthetic improvement and there was no evidence of relapse and any complication.
