Submucosal type cleft palate is a kind of cleft palate. A submucosal cleft may result in shortening of the anteroposterior dimension of the hard or soft palates or both. The increased distance along with the lack of muscle connection in the soft palate usually accounts for the lack of palatopharyngeal function in patients with submucosal cleft. Resonance disorders which is found in cleft patients show hypernasality or hyponasality. Many cases of submucosal type cleft palate patients visit our clinics due to hypernasality. In this study, resonance disorders was evaluated through nasalance test. Experimental group was composed of submucosal type cleft palate patients. The patients were treated by a so-called combined therapy, i.e., operation and speech training. To observe the changing pattern by surgery, nasalance test was carried out one time before surgery and three times after surgery. Nasometer II was used as a examination. The questionaire was filled with single vowels & diphthongs. The mean nasalance score of the child was significantly lower than that of the adult at every vowel. An early age at operation (under 10 years) was that a better functional result was achieved with patients. The mean nasalance score of /i/ was highest and that of /a/ was the lowest. The result of corrective surgery in selected cases has achieved improvement in all cases. Hypernasality has been consistently diminished. he operation.

The purpose of this study was to evaluate the frequency of congenital missing teeth and supernumerary teeth in cleft patients. The subjects were divided into bilateral cleft lip and palate(BCLP), unilateral cleft lip and palate(UCLP) and cleft palate alone(CP alone) groups. 97 cleft patients(BCLP 15, UCLP 70, CP alone 12) between 6-20 years old were evaluated. Panorama film, Orthodontic chart and initial intraoral photogram were employed for this research. The obtained results were as follows. 1. The incidence of congenital missing teeth in total cleft samples was $57.7\%$, and the incidence of supernumerary teeth was $26.8\%$. Each incidence was higher than non-cleft. 2. The incidence of congenital missing teeth was the highest in BCLP and the lowest in CP alone. 3. The number of congenital missing teeth per perso was usually one, and the frequency was higher in the maxillary lateral incisors$(67.8\%)$, and maxillary second premolar$(14.9\%)$ than other teeth. 4. Most of tooth number anomalies in cleft patients were found in maxilla, especially adjacent region to the cleft site.

Cleft lip and palate are most common congenital deformity to affect the orofacial region. Cleft lip and palate are caused by abnormal development of primary and secondary palate. It's causative mechanism is not completely understood, but genetic and environmental factors play an important role. Many epidemiologic surveys have been done extensively about incidence, racial influence, sex ratio, parent age, associated syndrome, and genetic factors. These researches are useful to dissolve many problems in prevention and treatment of cleft lip and palate. We performed epidemiologic survey of cleft lip and palate who visited the department of Oral & Maxillofacial surgery, Guro Hospital of Korea University from 1995 to 2001.

Cleft palate and congenital alveolar synechia is a rare syndrome. Only eight cases have been previously reported. It consists of a spectrum of facial anomalies always including cleft palate and congenital alveolar synechiae without other abnormalities. This report described an unusual case of congenital alveolar synechial band spanning posterior alveolar of the two jaws with cleft palate. Previously reported cases showed bilaterally or anteriorly located fibrous band. In our department, a new born revealed unilateral posterior synechia. Under brief intravenous sedation, synechium was divided using bipolar diathermy in the nursery at 3 days of age because of poor feeding. This division allowed full jaw opening after brief passive exercise. The patient is growing and maturing as expected with no complications. This patient is supposed to be the first reported case of isolated unilateral alveolar synechium combined with cleft palate in the worldwide.

Il Woong Cleft lip and palate foundation was founded in 1968 by Professor emeritus Byoung-Il Min. Since then the foundation has operated numerous cleft lip and palate patients not only in Korea but also in under-developed countries such as Vietnam, China, and Cambodia. In December 2005, the foundation was allowed as an incorporated association by Ministry of Foreign affairs and Trade, so that it could have official status. From March 6th 2009 to March 14th 2009, we conductp,d charity cleft lip and palate operations of 23 patients in areas of Deozhou, China. Hereby we present the results of operations.

Purpose: The oral teratoma is found approximately in live birth at the rate from 1 : 35,000 to 1 : 200,000. In a review of literature 16 cases of midline teratoma with cleft palate were reported. We report a case of congenital palatal teratoma with cleft palate in a 1-year-old girl. Methods: A 1-year-old girl was admitted our institution for the closure of cleft palate. On the intraoperative findings there was $4{\times}1{\times}0.5cm$ sized hairy soft mass at the midline and complete cleft palate. We did incisional biopsy intraoperatively and its pathology revealed heterotopic brain tissue. The excision of remaining mass and palatoplasty with Sommerlad's method were performed. The final pathology of the mass was mature cystic teratoma. Results: After the operation there were neither recurrence nor oronasal regurgitation. Conclusion: We report for one patient with congenital palatal teratoma associated with cleft palate and obtained an excellent result.

Background: Children with cleft lip and/or palate can be undernourished due to feeding difficulties after birth. A vicious cycle ensues where malnutrition and low body weight precludes the child from having the corrective surgery, in the absence of which the child fails to gain weight. This study aimed to identify the proportion of malnutrition, including the deficiency of major micronutrients, namely iron, folate and vitamin B12, in children with cleft lip and/or palate and thus help in finding out what nutritional interventions can improve the scenario for these children. Methods: All children less than 5 years with cleft lip and/or cleft palate attending our institute were included. On their first visit, following were recorded: demographic data, assessment of malnutrition, investigations: complete blood count and peripheral blood film examination; serum albumin, ferritin, iron, folate, and vitamin B12 levels. Results: Eighty-one children with cleft lip and/or palate were included. Mean age was 25.37±21.49 months (range, 3-60 months). In 53% of children suffered from moderate to severe wasting, according to World Health Organization (WHO) classification. Iron deficiency state was found in 91.6% of children. In 35.80% of children had vitamin B12 deficiency and 23.45% had folate deficiency. No correlation was found between iron deficiency and the type of deformity. Conclusion: Iron deficiency state is almost universally present in children with cleft lip and palate. Thus, iron and folic acid supplementation should be given at first contact to improve iron reserve and hematological parameters for optimum and safe surgery.

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.
