  • A General survey on the cleft lip and/or palate patients in Pusan National University Hospital was done. The conclusions were as follow. 1. In gender ratio, male was higher than female. 2. In the cleft type, unilateral cleft lip and palate, cleft lip and alveolus, and bilateral cleft lip and palate in higher ratio order. Left unilateral cleft lip and palate was higher than right in ratio. 3. In first hospital visiting age for dental treatment, the group from 6 years old to 12 years old was most and in that the age group for attending elementary school (about 7-8 years old) showed especially higher ratio. The large majority of patient were born in 1980's and lived in Pusan metropolitan city, KyungSangNamDo. Especially, most of them lived in the neighboring Held of Pusan National University Hospital. 4. Class III skeletal pattern and Angle's Class III molar relationship was most prevalent. Angle's Class II molar relationship showed relative higher ratio because tooth loss and malposition. 5. Primary lip closure in 3 months, secondary lip closure in 6-7 years old, palatal closure in 12-16 months and bone graft in 8-10 years old were operated mostly. Rhinoplasty and scar revision were operated in too early age so the need of infantile orthopedics must be considered. 6. Maxillary expansion and protraction were operated mostly in 8-11 years old but operating in primary dentition must be considered. 7. Tooth alignment were started mostly in mixed dentition and consideration about prosthodontic treatment and retention will be need. 8. In tooth anomaly, tooth malformation and missing were most prevalent.

A STUDY OF $TGF-{\beta}$ EXPRESSION DURING PALATOGENESIS IN RATS WITH CLEFT PALATE INDUCED BY BAPN (($TGF-{\beta}$ 발현이 BAPN으로 유도된 구개열 백서의 구개 형성에 미치는 영향에 대한 실험적 연구)

  • Cleft palate is one of the most serious congenital anomalies in human that causes a sucking problem in newborn babies and morphologic deformity that usually leads to death in newborn mouse offspring due to an insufficient ability to suck milk. Therefore cleft palate had been researched with epidemiologic and molecular methods, and many etiologic factors were examined closely. Among of the research methods, biologic molecule researches have been more important method for cleft palate formation study. The $TGF-{\beta}$ had an important role in the cell migration, epithelial-mesenchymal transdifferentiation, extracellular matrix synthesis and deposition. But there was a little research which was study about correlation cleft palate induced by beta-aminonitroproprionitrile(BAPN) with $TGF-{\beta}$ expression. A purpose of this presented study was examed how $TGF-{\beta}$ expression in cleft palate mice. At gestation days 13, BAPN-monofumarate salts($(C_3H_6N_2)_2$ ${\cdot}$ $C_4H_4O_4$, Sigma Co.) was single oral administered to 4 pregnant rats according to 1g/kg body weight. And pregnant rats were sacrificed on day 20 post coitus(p.c.), The $TGF-{\beta}$ expression patterns of cleft formed fetus mice was followed that; 1.Osteoblast, mesenchymal cell and epithelial cell of cleft mice were low expression compare to control mice. 2.There was no $TGF-{\beta}$ difference expression pattern of osteocyte of cleft mice compare to control mice. 3. In western blot analysis, thickness of band of $TGF-{\beta}$ in cleft mice was thin and dilute compare to control mice.

  • Distraction osteogenesis is useful treatment which the gradual separation of cut bone edges results in the generation of new bone. It is effective treatment for correcting maxillofacial deformities. Patients with cleft lip and palate usually have maxillary hypoplasia due to scarring of lip and palate. To correct these deformities, we chose to use a 2-jaw orthognathic surgery or distraction osteogenesis. But despite improvements in surgical techniques for maxillofacial deformities, postoperative stability still leaves the question of when relapse may occur. This case report describes the Relapse after treatment of maxillary hypoplasia with cleft lip and palate by Rigid External distraction system over a 2-year treatment and follow-up period. In addition, we reviewed related articles about the influence of the occlusal stability on postoperative stability in patients with cleft lip and palate correction with Distraction osteogenesis.

  • Cleft lip and palate is the most common congenital facial malformation and has a significant developmental, physical, and psychological impact on those with the deformity and their families. When treating the patients with unilateral cleft lip, many surgeons adopt the rotation advancement flap method originally developed by Millard, or the triangular flap technique developed by Tennison, Randall or the modifications of these techniques. Among these, Millard's rotation advancement flap method has its advantage in designing the flap using the patient's anatomic landmarks. For performing this rotation advancement technique, skillful operation is needed to obtain esthetically satisfactory results. Vomer flap sometimes is used to repair anterior hard palate in complete cleft lip and palate patients. Vomerine tissue is readily available in the vicinity of the palatal defect and elevation of the vomerine flap is relatively simple procedure. In this article, we will introduce the comprehensive vomer flap technique conjunction with primary lip closure and review the comparative studies of the outcome of simultaneous repair of cleft lip and cleft hard palate with Millard's rotation advancement method and vomer flap.

  • Cleft lip and palate is the most frequent congenital facial deformity of the orofacial area. Successful management of patients with cleft lip and palate requires a multidisciplinary approach from birth to adult stage. The early surgical intervention of lip and palate induces a significant incidence of maxillary growth restriction that produces secondary deformities of the jaws, and the severity of the skeletal discrepancies tends to increase with growth. The early growth modification treatment to utilize the patient's growth potential is necessary in the cleft lip and palate patients, and we must consider not only the existing skeletal discrepancies but the residual growth amount and the direction. However, once we have obtained good results with orthopedic treatment in mixed dentition stage, we must pay special attention to maintain the treatment results because of high relapse tendencies and the alterations of jaw relationships due to residual growth.
