Presurgical Lip, Alveolus, and Nose Approximation Versus Nasoalveolar Molding: Cleft Severity and Anthropometric Outcomes

Nasoalveolar molding (NAM) is an established form of presurgical infant orthopedics (PSIO), whereas presurgical lip, alveolus, and nose approximation (PLANA) is a novel approach. This study compared presurgical outcomes between infants with a unilateral cleft lip treated with PLANA and NAM using an objective method for assessment of cleft severity and PSIO outcomes. A single-institution retrospective review was conducted of all patients treated with NAM (2017-2019) and PLANA (2023-2025). Anthropometric measurements including columellar angle, nostril width ratio, and lateral subnasale displacement were collected at the initiation and completion of therapy, and predefined thresholds were used to classify patients by cleft severity (mild, moderate, severe, and very severe) and outcome (poor, good, and excellent). A total of 64 patients were identified, including 36 patients treated with NAM and 28 treated with PLANA. At baseline, the 2 cohorts exhibited similar distributions in cleft severity categories. At the completion of therapy, statistically significant differences were observed between NAM (27.8% mild, 52.8% moderate, 16.7% severe, and 2.8% very severe) and PLANA (67.9% mild, 28.6% moderate, 3.6% severe, 0.0% very severe). This translated to significant differences in PSIO outcomes between NAM (11.1% excellent, 55.6% good, and 33.3% poor) and PLANA (60.7% excellent, 35.7% good, and 3.6% poor). Numerically, the 2 cohorts were statistically similar at baseline, but after PSIO the PLANA cohort displayed more favorable anthropometrics and larger improvements in all 3 parameters. Using an objective method for evaluating cleft severity, patients treated with PLANA exhibited superior morphologic outcomes in comparison to NAM.
