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.

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.

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.

The purpose of the present study was to investigate the characteristics of receptive and expressive language development of cleft palate infants aged under 3. Twenty-six cleft palate infants and 52 normal infants were grouped into 3 chronological age groups with 1 year intervals: less than 1, 1, and 2 years old. The cleft palate infants were divided into 2 groups: cleft palate only, and cleft lip & palate. Each mother of the infants was asked to complete the questionnaire, Sequenced Language Scale for Infants (SELSI). Receptive and Expressive language scores of SELSI were computed. The scores of receptive and expressive language were respectively analyzed into 4 categories of language: phonology/prosody, semantics, syntax, and pragmatics. The results, concerning the differences of language development between the cleft palate and the normal infants, were as follows: (1) expressive language scores were significantly different at age 2 between the cleft palate and the normal infants; (2) cleft plate groups aged less than 1 and 1 showed lower scores of phonology/prosody of expressive language than the normal groups; (3) cleft palate group aged 2 showed lower scores than the normal group in semantics, syntax, and pragmatics. The results, concerning the characteristics of language development between the cleft palate only and the cleft lip & palate infants, were as follows: (1) the scores of expressive and receptive language were not statistically different between the 2 groups; (2) both groups did not show any difference in .the scores of phonology/ prosody, semantics, syntax, and pragmatics of receptive and expressive language.

구순열 및 구개열은 두개 악안면 부위에서 가장 자주 발생되는 선천성 기형으로 적절한 의료진의 확보와 의료 정책의 수립을 위해서 정착한 환자 수를 파악하는 것이 필요하다. 그러나, 기존의 국내 발생률 추정 연구는 표본선정의 문제점과 이 질환이 갖는 높은 유산율과 사산율 및 다양한 형태로 인한 분류의 어려움과 한국 내에서의 특수성 중 하나인 장애아들의 해외 입양으로 인해 정확한 환자 수의 파악이 어려웠다. 따라서, 한국인에서의 체계적인 유병률 연구가 필요하리라 사료되며, 대부분의 구순열 및 구개열 환자에서 필요한 교정 치료의 수혜 정도를 파악할 필요성이 있다고 사료된다. 이에 본 연구에서는 한국 성인 남자에서 구순열 및 구개열 환자에 대한 유병률과 이들에 대한 교정치료 수혜율을 조사하고자, 1998년도 병무청 징병 검사자 중 1979년도에 출생한 자만을 연구대상으로 하여 서울, 광주, 대구 부산의 성인 남자 218,322명에 대해 3단계 검사를 실시한 후 다음과 같은 결과를 얻었다. 1. 1979년 생 한국 성인남자에서 구순열 및 구개열 환자의 유병률은 1000명당 0.65명이었다. 2. 전후방적 심도에 따라 1000명당 각각의 유병률은 구순열이 0.26명, 구순구개열이 0.36명,구개열이 0.03명이었다. 구순열과 구순구개열은 비슷한 정도의 유병률을 보였으나, 구개열은 이에 비해 낮은 유병률을 보였다. 3. 횡적 심도에 따라 1000명당 각각의 유병률은 좌측 파열이 0.35명, 우측 파열이 0.16명, 양측 파열이 0.12명이었다. 좌측 파열은 우측 파열에 비해 매우 뚜렷하게 높은 유병률을 보였으며, 양측 파열은 편측 파열에 비해 낮게 나타났다. 4. 구순열 및 구개열 환자 중 성인남자에서의 한국 내 교정치료 수혜율은 $35\%$였으며, 구순열, 구개열, 구순구개열의 순으로 $28\%,\;29\%\;67\%$였다. 구순열이나 구개열과 같이 단독 발생된 경우보다 파열의 심도가 심한 구순구개열의 경우에서 교정치료 수혜율이 높게 나타났다.
