Case reports of bone grafting in unilateral alveolar-palatal cleft patients.: Yun Ho Bae, Jae Hyun Park, Myeong Jin Lee, Chang Gon Lee, Byung Rho Chin, Hee Kyeung Lee; Yeungnam Univ J Med. 1991;8(1):198-205. Published online June 30, 1991; DOI: https://doi.org/10.12701/yujm.1991.8.1.198

Abstract PDF: We obtained successful functional and esthetic results by grafting of iliac marrow-cancellous bone in 2 cases of alveolar-palatal cleft patients. Bone graft of alveolar-palatal clefts provide bony support to adjacent teeth of cleft area, prevented from relapse of orthodontic arch expansion, closure of oroantral fistula and improvement of speech problem. 1. In one case, extraction of upper right central incisor that was little bone support, alignment of rotated teeth and expansion of collapsed arch segment were done with pre-orthodontic treatment. The other case. Bone grafting was done after removal of prosthesis with no pre-orthodontic treatment. 2. After mucoperiosteal incision in cleft area, the mucosal flap of labial area, palate and nose were separation and the raised nasal mucosa was sutured for closure of oroantral fistula. Then, the iliac marrow-cancellous bones were grafted to cleft site. 3. After 6 months of operation, we had seen the new bone deposition to cleft site in dental radiograph and prosthetic treatment of missing teeth were done.

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. Published online June 30, 1990; DOI: https://doi.org/10.12701/yujm.1990.7.1.203

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.
