The Surgical Nasoalveolar Molding: A Rational Treatment for Unilateral Cleft Lip Nose Deformity and Literature Review
Percy Rossell‐Perry
Abstract
The purposes of this study were to evaluate surgical outcomes after primary surgery to address unilateral cleft lip, nose, and palate deformities and to perform a review of the literature to evaluate the effects of nasoalveolar molding (NAM) plus primary surgical repair on nonsyndromic unilateral cleft lip and palate. METHODS: A cohort study of 37 primary complete unilateral cleft lip nasal deformity repairs was performed by a single surgeon. The outcomes were anthropometric measurements of the repaired lip, nose, and alveolar cleft width at the age of 1 and 5 years. A review of the literature was performed for studies published until March 2020 to evaluate the effect of presurgical NAM on nasolabial aesthetics. RESULTS: Statistically significant differences were observed between pre- and postoperative columellar angle and alveolar cleft width. A total of 308 studies were identified, and 8 were included in the final analysis of 684 patients. The overall study quality was low according to the Oxford Centre of Evidence-Based Medicine, and GRADE level of evidence was low. CONCLUSIONS: Primary cheilorhinoplasty alone is a good approach to improve nose appearance and alveolar gap in patients with unilateral cleft lip nose and palate deformity. Definitive conclusions about the effectiveness of presurgical NAM cannot be drawn. Available scientific evidence is not sufficient to demonstrate that combined use of presurgical nasoalveolar molding and primary surgery provides better nasolabial aesthetic outcomes than does primary surgery alone.
