Cleft lip and palate deformity is a congenital defect of the middle third of the face. Incidence varies from 1:500 to 1:2500 live births. Etiology depends upon hereditary and environmental factors. Restoration of these defects is important not only for functional and esthetic reasons, but also because there may be a positive psychological impact for the patient and parents. The goal of primary closure of the lip for unilateral cleft lip is to ensure a normal and symmetrical lip and nose. Presurgical infant orthopedics has been employed since the 1950s as an adjunctive neonatal therapy for the correction of cleft lip and palate. Presurgical nasoalveolar molding (PNAM) represents a paradigm shift from the traditional methods of presurgical infant orthopedics. PNAM consists of active molding of the alveolar segments as well as the surrounding soft tissues. This clinical report describes a new approach of PNAM therapy for an infant with complete unilateral cleft lip and palate showing significant reduction in cleft defect size and improved contour and topography of deformed surrounding soft tissues.
唇腭裂畸形是一种面中部的先天性缺陷。发病率为每 500 至 2500 例活产儿中有 1 例。病因取决于遗传和环境因素。修复这些缺陷不仅是出于功能和美观的原因，而且因为患者和家长可能会有积极的心理影响。单侧唇裂的唇裂一期修复的目标是确保唇和鼻正常对称。自 20 世纪 50 年代以来，术前婴儿矫形术一直作为一种辅助新生儿治疗方法，用于矫正唇腭裂。术前鼻牙槽塑形术（PNAM）代表了从传统的术前婴儿矫形术方法的范式转变。PNAM 包括牙槽段以及周围软组织的主动塑形。本临床报告描述了一种用于完全单侧唇腭裂婴儿的 PNAM 治疗新方法，该方法显示出唇裂缺陷大小显著缩小，周围畸形软组织的轮廓和形貌得到改善。
