성장기 환자에서의 각 부위별 임플란트 식려 시기를 요약해보면 다음과 같다. 1) 상악전방부 : 외상이나 선천적 결손을 해결하는 방법으로 임플란트를 사용하는 술식이 권장하지만 성장이 완료되지 않았기 때문에 야기되는 문제를 해결하기 위해 성장이 완료될 때까지 연기하는 것이 좋다. 2)상악 후방부: 수직적인 성장량이 최고 1cm까지 일어날 수 있으면 상악동의 흡수로 조기에 임플란트 침강과 치근부의 노출을 야기할 수 있다. 그리고 동시에 보철에 의한 구개열의 횡적인 성장방해를 피해야한다. 3) 하악 전방부 : 무치증 아이에서 임플란트의 조기식립이 적응증이 되는 유일한 곳으로 치아가 없을 때는 치조골의 성장이 최소이며 초기에 횡적, 후방 성장이 대부분 완료된다. 그러나 단일 임플란트 식립은 권장되지 않는다. 4)하악후방부: 늦게까지 성장변화가 지속되기 때문에 전후방, 횡적, 수직적 성장의 많은 양이 일어난다. 하악의 회전성장의 영향을 많이 받아 하악 무치악에서 조기 임플란트 사용한 보고도 적고. 자연치아에 인접하여 임플란트를 식립한 기록은 있으나 골격성장이 완료될 때 까지는 식립하지 않는 것이 좋다.

Two patients with maxillary developmental deficiency who have previously undergone cheiloplasty and palatoplasty were operated on by simultaneous two jaw surgery and maxillary advancement surgery respectively. And the following results were obtained. 1. After the operation, maxilla shifted superiorly, and then inferiorly without noticible posterior relapse. 2. Postoperative mandibular relapse to the anterior direction was evident in both cases. 3. It is highly suggested that definitive measures to enhance postoperative stability in orthognathic surgery on the cleft lip and palate patients be developed.

Since the emergence of neonatal infant orthodontics for treatments of cleft lip and palate with or without Robin sequence (RS) in Europe in the 1950s, advancements in design and scope of its application have been remarkable. As the first institution to adopt orthodontic airway plate (OAP) treatment in the United States in 2019, we saw a need for innovation of the original design to streamline the most labor-intensive and time-consuming aspects of OAP utilization. A solution is introduced using a systematic split expansion mechanism to re-size the OAP periodically to accommodate the neonate's maxillary growth. To date, seven RS patients have received this modified treatment protocol at our institution. Each patient completed full treatment using only one OAP. This innovative utilization method is aptly named the split orthodontic airway plate (S-OAP). Details of the S-OAP and its modifications from conventional OAP are reported.

한국얼굴기형환자 후원회 의료봉사팀은 2010년 2월 6일에서 12일까지 라오스의 수도인 Vientiane을 방문하여 구순구개열 무료수술을 무사히 마쳤다. 의료봉사팀은 총 11명으로 구성되었다. 구강악안면외과의 6명과 간호사 2명, 학생 3명이었다. 수술은 라오스 비엔찬의 Mahosot 병원에서 수술장 한개에 수술 침대를 두개 놓고, 두팀을 구성하여 수술을 진행하였다. 당시 서울대학교 치과대학 예방치학교실 백대일 교수님께서 안식년을 맞아 라오스에서 라오스인 구강건강에 관한 national survey를 수행하고 계셨는데 수술팀에게 많은 도움을 주셨다. 2월 7일 토요일 예진 때는 한국국제협력단에서 파견한 국제협력의사 박병원 선생님(내과 전문의)께서 통역으로 도와 주셨다. 총 30명의 환자가(남:여=14:16) 수술을 받았으며, 환자들의 평균 나이는 9.7세였다. 수술 종류는 cheiloplasty, palatoplasty, rhinoplasty, scar revision, lip reconstruction로 구분 지을 수 있었으며, 모든 수술은 합병증 없이 마무리되었다. 이번 자선수술을 통해 30명의 환자를 수술하였고, 라오스 의사들에게 구순구개열 진료에 대한 기술을 교육할 수 있었다. 또 라오스 치과대학과 자매결연을 맺는 등 한국-라오스 우호증진에 많은 기여를 한바 이를 보고한다.

Objective: This study was performed to identify the characteristics of the MSX1 gene (locus chromosome 4p16) in Korean nonsyndromic cleft lip and palate (CL/P), which is assumed to be a major candidate gene acting as a causal factor in nonsyndromic CL/P and missing teeth. Methods: The 36 individuals (23 males and 13 females) who had visited the department of orthodontics at from 1998 to 2002 and who had nonsyndromic CL/P were included in the study. Using a PCR-based assay, the MSX1 gene was amplified, sequenced, and searched for inferred protein products (Reference: Homo sapiens MSX1, accession number AF426432 and NP_002439). The common single nucleotide polymorph isms were observed. Results: In exon 1, nucleotide "A" of the 253 basepair (bp) region was substituted for "G", and in the 255 bp region, nucleotide "G" was inserted. In exon 2, nucleotide "C" of the 11 bp region was substituted for "A", and "T" or "G" was inserted into the 351 bp region whereas "T" or "A" was inserted into the 352 bp region. In protein analysis, "Thr85Ala" missense mutation was found. The "Thr85Ala" missense mutation in this study is different from those of studies using subjects of other races. Conclusions: The results suggest that there is specific mutation of MSX1 in Korean and it plays an important role in Korean nonsyndromic CL/P. However, any distinct genetic polymorphisms between CL/P with missing teeth in the cleft region and CL/P without missing teeth could not be found.

Oronasal fistula are a well-known complication of surgical treatment of cleft palate, occurring most frequently in the alveolus and hard palate. Previous reports have demonstrated that oronasal fistulas, particularly if greater than l cm in diameter, had an adverse effect on speech. The aim of this study was to demonstrate the relationship between the size of the fistula and the influence on velopharyngeal function. The site and size of the fistula were indicated on graph paper with calipers and measured in $mm^2$. Speech assessment was carried out using a Nasometer, VPI articulation differential test, spectrography. Patient whose fistulas affected their speech had significantly larger fistulas than those whose fistulas did not. The study shows that the larger the fistula, the greater the risk of hypernasality and nasal emission, but even small fistulas can cause speech problems. If obstruction of the nasal passage is eliminated in a patient with a previously asymptomatic fistula, it may result in a fistula becoming symptomatic, resulting in hypernasality and nasal emission. In conclusion, even small fistulas can influence speech production and should be considered before any treatment is planned. The study lends support to early closure of oronasal fistulas, particularly before pharyngeal flap surgery is contemplated.

The purpose of this study was to obtain normative nasalance scores for adult subjects speaking the Korean language. Additional objectives of the study were to determine if speaker sex played a role in differences in nasalance score and there was significantly correlation of nasalance score with nasalance slope score. The subjects include 75 healthy young Korean adults with normal oral and velopharyngeal resource and function. They had no history of speech problem, were judged as having normal speech and resonance at the time of testing, and had no upper respiratory tract infections or allergies at the time of testing. The Nasometer II 6400 was used to obtain nasalance scores and nasalance slope scores for /a/, /i/, /e/, /o/, /u/, /ja/, /je/, /wi/, /p'ap'i/ and /sasi/. The data of nasalance and nasalance slope were analyzed statistically. The mean nasalance score of the female was significantly higher than that of male at /a/, /i/, /wi/, /p'ap'i/ and /sasi/(p <0.10). The mean nasalance score of /i/ was highest and that of /o/ was the lowest. In this study, we could not and the relationship of the nasalance score and the closing slope score. However, there was negative correlation between the mean nasalance score and the opening slope score at ie/ and /;ai, positive to /sasi/. These normative nasalance scores for normal young adults speaking the Korean language provide important reference information for Korean cleft palate teams. In the future study of velopharygneal activity with the Nasometer, the opening slope score will be able to be the important parameter.
