Abstract

Cleft lip and palate(CLP) is one of the most common craniofacial deformities that requires systemic management involving a multidisciplinary team approach. Although there has been great improvement in the field of cleft surgery, surgical approach alone cannot resolve the various problems in treating cleft lip and palate. Hence the need for presurgical treatment was appreciated and especially, the concept of presurgical nasoalveolar molding was applied to treat unilateral and bilateral cleft lip and palate patients. Presurgical nasoalveolar molding(PNAM) of unilateral cleft mainly aims to recover nasal symmetry while the objectives of pre-surgical nasoalveolar molding in the bilateral cleft are to elongate the columella, to erect the tip of nose, and to reposition the forward displaced premaxillary region. This report covers the case of fraternal twins diagnosed with bilateral cleft. Retraction of the premaxillary region and nasoalveolar molding were conducted for 70 days until cheiloplasty, using elastic bands and nasoalveolar molding appliances. After cheiloplasty, there had been improvements in the length of columella and the position of forward-displaced premaxilla for both patients compared to their initial states. The esthetics was also satisfactory for both the surgery and the parents. In order to maximize the efficacy of the appliance, three components should be in balance; patients' adaptation to the appliance, parents' cooperation and proper selection and careful adjustment of the appliance by the dentist.

구순구개열은 선천성 악안면 기형 중 발생률이 가장 높은 질환으로 관련된 여러 분야의 협진(team approach)을 통한 조직적인 관리를 필요로 한다. 치료에 있어 수술분야의 많은 발전이 있어 왔으나 수술만으로는 다양한 문제점을 해결하기 어려웠다. 이에 따라 술 전 처치의 필요성을 인식하여 술전 비치조 정형의 개념이 개발되었으며 편측성 및 양측성 구순구개열 환자에게 적용되고 있다. 편측성 구순구개열에서 술전 비치조정형의 목적을 코의 대칭성을 회복시키는데에 중점을 두었다면 양측성 구순구개열에서는 짧은 비소주를 신장시키고, 낮아진 코끝을 세우고, 전방으로 변위된 전상악부를 재위치 시키는 것이 목적이라 할 수 있다. 본 증례에서는 양측성 구순/구개열로 진단받은 이란성 쌍둥이에게 술전 탄성밴드와 비치조정형 장치를 이용하여 첫 번째 입술수술 전까지인 약 70일간 전상악부의 후방 견인 및 술전 비치조정형을 시행하였다. 두 환아 모두 초기에 비해 비소주가 길어지고 전방 변위된 전상악부가 제 위치로 많이 회복된 것을 관찰할 수 있었다. 그리고 입술 수술 후 술자와 보호자가 모두 만족할만한 심미적인 결과를 얻을 수 있었다. 장치의 효과를 극대화하기 위해서 환자의 적응력, 보호자의 협조도 및 술자의 적절한 장치물의 선택과 세심한 조정, 이 3가지 요소가 조화를 이루어야 할 것이다.
