The case unveils an early orthodontic intervention on 3-week old infant innately with bilateral cleft lip and palate. Presurgical Nasoalveolar Molding(PNAM) procedures were carried out for 2 months for the sake to diminish the anticipated strain of postsurgical scar by means of the retraction of protruded premaxilla and the extension of collapsed columella. The gap on the alveolar cleft decreased by 2,5 mm, and the columella manifested 1. 5 mm increase of its length, which yielded the consequent downward and backward movement of premaxilla, and expected to bring down the technical complexity of primary lip surgery. PNAM with sophisticated technical procedures at an optimal timing disclosed the passive molding of the alveolar segments and the formation of nasolabial soft tissue integuments and permitted one-time primary lip surgery.

The purpose of this study is to investigate possible correlation between the dental anomalies and site of cleft in cleft lip and palate. In this study, 142 patients who had cleft lip and/or cleft palate were examined. The results are as follows. 1. The incidence of missing tooth was high in the permanent dentition as compared to the incidence in the deciduous dentition. 2. There was not much difference of incidence of supernumerary tooth between deciduous and permanent dentition in the group of patients who had cleft lip and jaw with or without cleft palate. 3. In the group of patients who had cleft lip and jaw with or without cleft palate, the frequency of incidence of cleft sides was higer in unilateral than bilateral cases. And, incidence of left sides was higher than right sides. 4. The type of cleft between central incisor and canine with missing lateral incisor was most frequent in permanent dentition and the type of cleft between central and lateral incisor was most frequent in deciduous dentition. 5. The type of cleft associated with tooth position in deciduous dentition was not almost the same in the succeeding permanent dentition.

The role of the Orthodontist in cleft lip and cleft palate therapy is primarily ill correction of malocclusion which is required by practically every child who has these defects. He can contribute to the assessment of dento-facial growth and development. We may gain the possible limited correction of delayed malocclusion due to cleft lip and palate. The authors have attempted delayed orthodontic treatment of a cleft lip and palate of 12.9 years old girl, who had a cleft lip and palate of surgical closure at 2,3 and 4 years old.

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.

Recent aerodynamic and acoustic studies of VPI(velopharyngeal insufficiency) are non-invasive and safety, therefore, many researchers have used it to diagnose the hyper/hyponasality and articulation disorders of cleft palate patients. The purpose of this study was to estimate mainly the oropharyngeal air pressure and over all air flow in cleft lip and palate patients. The pressure-collecting catheter was positioned in the oropharyngel cavity around tongue base. Twelve adult control group and three cleft lip & palate patients were participated to this experimentation. Aerophone II was used to measure peak air flow, mean air flow, phonatory airflow, phonatory efficiency and resistance. The results were as follows: 1) Airflow of cleft lip ＆ palate patients group were higher than those of control group. Fricative sounds /s/ and /s'/ showed the statistic significance of mean airflow and volume data. 2) Intraoral air pressure of cleft lip ＆ palate patients was lower than those of control group.

Cleft lip and palate are most common congenital defomity to affect the orofacial region. Cleft lip and palate are caused by abnormal development of primary and secondary palate. Its causative mechanism is not completely understood, but genetic and environmental factors play important roles. Lots of 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 and Maxillofacial Surgery, Guro hospital of Korea University from 1995 to 2004.

The dissimilarities between South and North Korea have persisted in spite of the reconciliation campaign by both countries. The situation of the cleft lip & palate of North Korea was very unclear until now. The purpose of this study is to understand all the current facts of cleft lip & palate in North Korea so that we can find ways of helping North Korea in this field of medicine. The present data and analysis are extracted from North Korean textbooks. The results are as follow. 1. In North Korea, patients with CLP are treated by oral surgeons or maxillofacial surgeons. The detailed contents about the CLP are well described in the North Korean textbooks for the dental students. 2. The terminology of CLP in North Korea has changed from time to time, but the present terminology not being so different from South Korean counterpart. So there will be no particular problems in mutual communication. 3. The main classification for CLP in North Korea originated from Kernahan & Stark's classification as is with South Korea. 4. The incidence of CLP is 1 : 1,000-1,200 in North Korea, which is lower than that of South Korea. There is, however, some difference between the North and South Korean CLP in detailed statistics. 5. We found the North Korean physicians have shown much interest in pursuing the etiology and the prevention of CLP. 6. The timing of CLP operations varied a lot in North Korea. There was recommendation by few for the operation in much late age than in South Korea. 7. The classical operation techniques of cleft lip have changed. For unilateral cleft lip Tennison-Randall method was replaced by Millard I method: and for bilateral cleft lip LeMesurier method was replaced by Veau III and Tennison methods. But for cleft palate Pushback palatoplasty has been utilized consistently.
