구순열의 일차 수술 또는 이차 수술 후에 발생하는 상순의 지나친 긴장은 상하순 간의 부조화, 상악열성장, 골격성 III급 부정교합 등 안모추형을 초래한다. 상순의 긴장이 매우 심한 경우에는 하순의 여유 있는 조직을 이용하여 상순을 수정하는 Abbe 피판을 고려할 수 있다. 상순의 긴장이 큐피드궁의 2/3 이상의 조직 손실을 동반할 경우 Abbe 피판의 적응증이 된다. Abbe 피판은 상순과 하순의 반흔, 색상의 부조화, 그리고 상순의 불완전한 운동을 초래하는 단점을 가진다. 그러므로 Abbe 피판은 신중하게 사용되어야 한다. 우리는 편측성 구순열 1예와 양측성 구순열 3예에서 상순의 과도한 긴장과 큐피드궁의 조직 결핍 그리고 비변형이 심한 이차성 구순열비변형을 교정하기 위해 세 가지 형태의 Abbe 피판을 이용한 이차 교정술을 경험하였다. Abbe 피판수술을 시행한 결과 상순의 반흔과 긴장이 해소되고 큐피드궁이 재건되고 비주의 길이가 증가되어 이차 구순열비변형을 교정할 수 있었다. Abbe 피판은 신중을 기해 적용한다면 구순열 수술 후에 발생되는 상순의 수평적 긴장감이나 편평함을 해결하는 데 유용한 술식임을 알 수 있었다.

본 연구의 목적은 1) 양측성 순구개열 신생아에 대한 수술전 비치조정형 장치 (Pre-surgical nasoalveolar molding appliance, PNAM) 치료를 소개하고, 2) 이 장치의 치조골 조형 (molding) 효과를 평가하는 것이다. 서울대학교병원 교정과에 내원하여 PNAM 장치를 사용하여 치료받은 8명의 양측성 순구개열 환자 (남자 7명, 여자 1명, 평균 초진 연령:61.6일)를 연구대상으로 하였으며, 치조골에서 전상악골의 치조능 좌우측 말단부와 양측 분절 치조능 최전방점까지의 파열부간 평균거리는 $8.09{\pm}5.03mm$였고 치조골 정형치료의 평균 기간은 $8.8{\pm}3.1$주였다. 초진시 (T0)와 성공적인 치조골 정형술이 완료된 시기(T1)에 인상을 채득하여 모형을 제작한 후, 사진 촬영과 digital caliper를 사용하여 20개의 길이항목과 14개의 각도항목을 계측하였다. Microsoft사의 Excel 97 program을 사용하여 각 항목의 계측치들을 통계 처리하였고, 치조골 정형술에 의한 치료전후의 차이를 비교하기 위하여 paired t-test를 사용하였다. PNAM 장치에 의한 치조골 조형 효과에 대한 결론은 다음과 같다. 1. 양측성 순구개열 파열부의 폐쇄가 성공적으로 이루어졌다. 2. 양측 분절의 측방 성장이 억제되어 내측 굴곡이 발생하였다. 3. 전상악골 후방부에 위치한 서골(vomer) 전방부의 굴곡에 의하여 전상악골의 후방이동과 회전이 발생하였다. 구순성형술을 시행하기 전에 PNAM장치를 사용하여 양측성 순구개열 신생아 환자의 파열부 폐쇄에 대한 좋은 결과를 얻을 수 있었다.

The treatment of cleft lip and palate must be based on a complete knowledge of the anatomy, physiology and growth of the involved deformity, because of not only the appearance but also impaired functions such as phonation, mastication, respiration and lingual posture of the maxillomandibular complex. Delaire has long studied all these aspects, and has published many numbers of articles and constructed a philosophy concerning the significance and interrelationship of the various structures. The results obtained from its application seem to be particularly valid from a clinical point of view, although it has not all been scientifically supported by experimental data. For these reasons, Delaire's primary unilateral and bilateral cheilorhinoplasty procedures are particulary good, as is his secondary gingivoalveoloplsty procedure during the course of the surgical repair of the hard palate. In order to understand Delaire's philosophy, it is necessary to consider the normal and pathologic anatomy of the structures involved in the deformity, the role of some structures, such as nasal septum, musculature, and tongue, and some functions, such as dental occlusion or nasal respiration, which play important roles in maxillary and particularly premaxillary growth. Despite of important concept and meanings, Delaire's philosophy has not been introduced widely to our Korean cleft surgeons yet. So authors will summarize the basic concepts of Delaire's philosophy according to already published literatures and lectures based on our previous treatment outcomes.

양측성 구순구개열을 가진 16세 여자 환자가 소구증과 구순열비변형으로 인하여 개구 제한과 심미적 문제를 주소로 내원하였다. 병력에서 구순성형술, 구개성형술 그리고 이차구순비성형술을 받았으며, 임상 소견에서 상순과 하순이 매우 작고 입술의 폭은 40 mm 정도로 짧았으며 최대 개구량은 20 mm였다. Converse의 협점막 외전 피판을 이용한 양측성 구각성형술을 시행하였으며 수술 후 입술의 폭은 60 mm로 증가하였다. 수술 1년 경과 후 입술의 폭은 54mm로 약 6 mm 정도 회귀되었고, 그 외에 별다른 문제점 없이 심미적, 기능적으로 양호한 결과를 보였다. 협점막 외전 피판을 이용한 양측성 구각성형술은 입술의 폭과 크기를 증가시켜주고 입술의 외관을 개선하여 소구증의 외과적 교정에 적절한 술식임을 알 수 있었다.

Palatoplasty using Furlow's double-opposing Z-plasty has been performed from June, 1995 to September, 1999 at Seoul National University Children's Hospital. The goal of this study is to determine the optimal timing of repair and cleft severity affecting velopharyngeal function. This is the retrospective study of patients operated by the second author. The mean age of patients was 10.53 months. The patients could be divided into three groups-isolated cleft palate(n=70), unilateral cleft lip and palate(n=88), and bilateral cleft lip and palate(n=42). To evaluate the velopharyngeal function, we used two parameters, speech evaluation and cineofluorography using DSR(digital subtraction radiography). Also, to determine the relevance between cleft severity and speech development, we measured the distance between maxillary tuberosities and cleft margins. Among 200 patients, about 96% had no or minimal hypernasality and 87% had no or mild nasal emission. The cleft width and length of soft palate seemed not to be related with the speech development. Palatoplasty at the age under 12 months resulted in less 'nasal emission' and better 'articulation' of the parameters that were assessed at the age of 7 years. It can be concluded Furlow palatoplasty shows satisfactory results and also it seems that it is better to perform the operation before the age of 12 months.

This study is aimed to elucidate the abnormal growth pattern of human fetal maxilla with cleft lip and palate (CLP). Total 71 fetal maxillae with CLP were obtained from aborted human fetuses. They were examined radiologically for the dimensional changes of maxillary trapezoid (MT) formed by maxillary primary growth centers (MxPGC)(Lee et al., 1992). In palatal radiogram of the CLP maxilla, the MT was traced by the anterior and posterior MxPGCs, and the dimensions of anterior and posterior maxillary widths, maxillary length, and MT length (MTL), and MT area were measured for evaluation of the basic growth pattern of the developing maxilla. The growth of anterior and posterior MxPGCs was severely retarded in the prenatal maxillae with CLPs, showing abnormal shape of MT. Cleft lip subjects without cleft palate also showed arrested growth of MT. Unilateral cleft lipalveolar cleft or cleft palate (UCL-AC/CP) and bilateral cleft lip-alveolar cleft or cleft palate (BCL-AC/CP) showed enhanced abnormal MT pattern. The abnormality of MT was most marked in BCL-AC/CP. It was also observed that the craniofacial malformations other than CLPs produced abnormal MT. In conclusion, the MT growth of prenatal CLP maxilla was severely arrested and resulting in abnormal MT shape on the palatal radiogram. BCL-AC/CP showed more protruded nasal septum than other types of CLPs, while UCL-AC/CP showed severe deviation of the protruded nasal septum towards the non-cleft side. Cleft lip only subjects also showed the abnormal growth of MT. These data suggest that the MT is primarily involved in CLPs, and MT shape could be utilized as a sensitive indicator for the analysis of maxillary malformation in different types of CLPs.

Purpose: The common deformity after the correction of unilateral cleft lip nasal deformity is nasal asymmetry, and it is caused by the hypoplasia of the pyriform aperture. To correct this, many procedures have been applied, but still many problems are present. Authors performed the inlay and onlay insertion of porous high density polyethylene sheet(1 mm thickness $Medpor{(R)}$ sheet) in the hypoplastic pyriform margin of cleft side and obtained satisfactory results. Methods: 11 cases were performed and the mean follow up period was 15.1 months. Their mean age was 23.6 years. Under general anesthesia, bilateral pyriform margin was exposed. $Medpor{(R)}$ sheets in "match stick" like shaped were inlay inserted, and kidney shaped were onlay inserted fixating with two 6 mm titanium screws. After the surgery, the results was evaluated by photogrammetric analysis. On the basal view, the distance from the subalare and labiale superius' to the transverse baseline connecting the both cheilions was measured from the cleft side and the non-cleft side. Then, the postoperative symmetry was assessed by obtaining the cleft side against the non-cleft side as proportion index, defined as lateral and medial upper lip contour index. Results: There were 2 infections. The cause was because the inserted implant was too long and thus protruded to the base of nasal cavity. The lateral upper lip contour index was from 95.49 to 103.27, and medial upper lip contour index was from 90.92 to 100.49, it was statistically increased, and thus the symmetry was improved. However clinically mild depression remained at nostril floor. Conclusion: Authors performed porous high density polyethylene sheet inlay and onlay insertion for the hypoplasia of the pyriform margin in unilateral cleft lip nasal deformity. It was found that depressed pyriform margin and upper lip were corrected effectively except for the nostril floor, for which an additional soft tissue augmentation would be necessary. The inlay insertion has risk of protrusion, thus the guideline of the use of artificial prosthesis should be observed strictly.
