OBJECTIVE The aim of this study is to assess the esthetic and morphologic outcomes before surgery using nasoalveolar molding (NAM) therapy in children with unilateral cleft lip and palate. DESIGN A prospective analysis was performed. SETTING The study was carried out in the Congenital Malformations Craniofacial and Cleft Lip and Palate Unit, Hospital Virgen de las Nieves, Andalusian Health Service, Granada (Spain). PATIENTS Twenty consecutively enrolled infants ranging in age from 7 to 30 days with nonsyndromic unilateral cleft lip and palate treated from 2008 to 2012. INTERVENTIONS All patients were treated with NAM appliances to align the alveolar segments and reduce severity of the nasal deformity. MAIN OUTCOME MEASURE The extraoral nasal measurements were performed on casts and nasal photographs. The measurements consisted of bialar width (BAW), columellar deviation (CD), cleft nostril height (CNH), cleft nostril width (CNW), non-CNH, non-CNW, and the deviation of the columella to the horizontal line represented by bilateral pupil line (BIA). The authors have made the measurements following Barilla method. Also 2 intraoral measurements were taken. RESULTS Following NAM the extraoral records showed a statistically significant decrease in CD (P
