  • The closure of a wide alveolar cleft and fistula in cleft patients and the reconstruction of a maxillary dentoalveolar defect in bilateral cleft lip and palate (BCLP) patients are challenging for both orthodontists and oromaxillofacial surgeons. It is due to the difficulty in achieving complete closure by using local attached gingiva (palatal flap) and the great volume of bone required for the graft. In this article, the authors used bifocal distraction-compression osteosynthesis(BDCO) to create a segment of new alveolar bone and attached gingiva for the complete approximation of a wide alveolar cleft/fistula and the reconstruction of a maxillary dentoalveolar defect. Since the alveoli and gingivae on both ends of the cleft were approximated after BDCO, the need for extensive alveolar bone grafting was eliminated. It also could create new alveolar bone and gingiva for orthodontic tooth movement and implant.

  • The congenital deformities of cleft lip and cleft palate have been known to afflict man since prehistoric time. Efforts to correct these abnormities have evolved over the centuries as scientific knowledge has advanced. Although there is no agreement as to when the surgery should be performed, most surgeons adhere to "rule of 10" : the infant must be 10 week old weigh 10 Ibs, have a hemoglobin value 10gm/dl and have a white blood cell count no greater than 10 $thousands/mm^3$. Consensus favors performing initial palatal surgery in the child when he is between 18 and 24 months old. The timing of cleft alveolus surgery is usually between 10 and 11 years old. In the period from 1992 to 1996, 38 patients with cleft lip and cleft palate treated at the department of oral and maxillofacial surgery, Chosun university, dental hospital were analysed clinically. The obtained results were as follows. 1. The ratio of male to female was 1.92 : 1 (25/23) 2. The ratio of cleft lip, cleft palate and cleft lip & palate was 1.5 : 1 : 2.5 (12/8/18) 3. The ratio of unilateral to bilateral cleft lip was 5 : 1 (25/5) 4. The ratio of left to right side in unilateral cleft lip was 1.5 : 1 (15/10)

  • A 20 year-old cleft lip and palate patient came for occlusal rehabilitation, but the constricted maxilla and early loss of posterior teeth called for an unusual treatment modalities. Distraction osteogenesis in the edentulous areas followed by artificial bone graft, dental implant along with orthodontic tooth movement were planed. Multidisciplinary treatment enabled both esthetic and functional oral rehabilitation of this patient.

  • A 7-month-old, weak female dachshund dog which had signs of cough and sneezing while eating was admitted. This case was diagnosed as cleft hard palate by the physical and blood examination. After aseptic surgical preparation, a surgical method utilizing mucoperiosteal and buccal flap technique, in which accurate apposition and secure closure was very important, was used successfully. The defect of hard palate was healed completely on 10 days after surgery without any other complication.

  • In order to understand the effects of all-trans-RA on palate development, RA was injected into the abdominal cavity of pregnant mice and then the embryos were taken in the following days and analyzed morphologically as well as molecular biologically. When RA was administered at the stage of E11 or E15, the overall craniofacial development was retarded. The length from jaw to eye was shortened, compared to that of normal group. When the E11 embryos were exposed to RA, cleft lip was also found along with the cleft palate. In vitro palate culture experiment also revealed that RA caused cleft palate. When RT-PCR was performed, early stage administration of RA at E11 inhibited the upregulation of Hoxa7 expression at E15 through E17. Whereas in control group, high level of Hoxa7 expression was detected in the palate of E15 to E17. In the case of Bax, the expression was decreased from E16, while remaining constant in control group. When TUNEL analysis was performed following the RA treatment at E15, TUNEL positive cells were detected in the mesenchymal cells as well as epithelial cells of palatal shelves of E16 and in E17 embryos. Whereas in normal control, TUNEL positive cells were observed mostly at the epithelium around the nasal cavity and oral cavity where rugae is made. These results altogether indicate that exposure to RA during palate development causes facial deformity including cleft palate and cleft lip by modulating the expression of homeotic genes such as Hoxa7 as well as an apoptosis-related gene, Bax, and thus malregulating the apoptosis.

  • This study was designed to evaluate the morphology and the position of the mandible in the complete unilateral cleft lip and palate patients, Craniofacial skeletal morphology pattern was analyzed on the lateral cephalometric radiographs of the 50 subjects of complete unilateral cleft lip and palate, the 50 normal and 50 class III, Each group was divided into child and adult sub-groups, All the data were tested statistically. The results were as follows: I, In the comparison with the normal group, complete cleft group showed smaller angular, condylar length, clockwisely rotated mandible and larger NMe/SGo(p<0.01). 2, In the comparison with the class III group, the complete cleft group showed significantly smaller angular, condylar, ramal, body length of the mandible(p<0,01). 3. As for the position of the mandibular condyle to the cranial base, the class III group was the most anterior, the normal group was the most posterior and the complete cleft group was in the middle(p<0.05). 4. In the comparison with child group, the normal adult group showed smaller mandibular angle and mandibular plane angle, but not the other two groups. And the complete cleft group and the class III group showed the similar change. The normal and class III group showed increased XiCd/XiPog, but not the complete cleft group(p<0.01).
