A case of orthognatic surgery in congenital alveolar-palatal cleft patient.: Jae Hyun Park, Myung Jin Lee, Chang Kon Lee, Jong Sub Kim, Byung Rho Chin, Hee Kyung Lee; Yeungnam Univ J Med. 1992;9(1):189-196. Published online June 30, 1992; DOI: https://doi.org/10.12701/yujm.1992.9.1.189

Abstract PDF: Pre-surgical and post-surgical change in adult clef lip and palate patient following Le Fort I advancement osteotomy combined with bone graft was evaluated clinically and cephalometically. We obtained a successful function and esthetic improvement. The bone graft of alveolo-palatal clefts provides a stable bone support to the adjacent teeth of the cleft area, and well union of adjacent bone tissue, the closure of oronasal fistula and improvement of speech problem. Le Fort I osteotomy following the ostectomy of nasal septum for advancement of the maxilla was obtained relative improvement of esthetics and functional occlusion. 1. The orthodontic correction was required before and after surgery. 2. In this case, there was a limited range of anterior advancement of the Premaxillary-segment due to the scar tissue. 3. After 8 months of operation, we could show the new bone deposition on the cleft sites in dental radiograph and then the prosthetic treatment to the missing teeth was done.

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.
