Abstract

Cleft lip and palate, the most common craniofacial anomalies, are severe congenital defects that have an incidence of 0.28 to 3.74 per 1000 live births. Although there has been great improvement in the field of cleft surgery, surgical approach cannot be the single solution to resolve the various problems encountered in patients with cleft lip and palate. The concept of presurgical infant orthopedics (PSIO) for gradual closure of the cleft gap and simplified surgical performance was first introduced by McNeil in 1950. Recently, there are many attempts not only to approximate the alveolar segments but also to reshape the nasal cartilage. Three infants with unilateral cleft lip and palate were referred from the department of Plastic Surgery for presurgical nasoalveolar molding (PNAM). Maxillary appliances using resin with orthodontic wire were fabricated. Then these appliance was applied until patients underwent lip surgery. In all cases, the patients could wear the appliance all day since they were able to eat even with the appliance on, This resulted in significant improvements in the nasal symmetry were found. Our appliance, namely K-NAM, extends the wearing time within the limited period and as a result it is expected to maximize the treatment effects. Used properly, this appliance would play a major role in enhancing nasal symmetry with satisfactory results.

구순구개열은 얼굴에 발생하는 다양한 종류의 기형 중 빈번히 발생하는 기형으로, 발생 빈도는 일반적으로 1000명당 0.28~3.74명으로 알려져 있으나 파열의 종류, 인종 및 성별에 따라 큰 차이를 보인다. 구순구개열의 치료는 수술영역에서 많은 발전이 있었지만 수술만으로는 문제점을 해결하기는 어렵다. 파열부 간격을 줄이고 구순열 수술을 용이하게 하기 위한 술전 신생아 정형술의 개념이 1950년 McNeil에 의해 개발되었으며, 최근에는 술전 비치조 정형장치(presurgical nasoalveolar molding appliance, PNAM)를 사용하여 치조골뿐만 아니라 코의 모양을 정상화하려는 시도가 이루어지고 있다. 세 명의 환자가 편측성 구순구개열로 진단받은 후 술전비치조정형장치 장착을 위해 의뢰되었다. 레진과 교정용와이어를 이용하여 제작한 K-NAM 장치물을 입술 성형 수술을 시행하기 전까지 장착하였다. 첫 내원시와 nasal molding을 시행하여 입술 성형 수술을 하기 직전, 입술 성형 수술 이후 콧구멍의 높이, 너비, 비주의 각도를 측정하여 비교한 결과 세 증례에서 모두 코의 대칭성이 증가하며 술 후 심미개선에 효과적임을 알 수 있었다. K-NAM 장치물은 장치의 장착, 유지, 조절이 용이하고 장착한 상태에서 수유가 가능하기 때문에 장착시간을 증가시킬 수 있다. 따라서 nasal molding이 가능한 한정된 기간 안에 최대의 효과를 기대할 수 있다. 그리고 젖병을 빠는 행위가 가능해짐으로써 동시에 구강조직의 발달에도 도움을 줄 수 있을 것이라 생각한다.
