An assessment and comparison of nasolabial aesthetics in bilateral clefts using the anatomical subunit-based scale: a nasoalveolar moulding versus non-nasoalveolar moulding study.

Nasoalveolar moulding is a presurgical orthopaedic technique used to improve the outcomes of bilateral clefts. However, the lack of a validated scale tailored to bilateral clefts makes it difficult to quantify the merits of nasoalveolar moulding and compare it to other techniques. In this study, a recently published anatomical subunit scale was used to evaluate and compare the early effects of nasoalveolar moulding. Two groups of similarly treated bilateral cleft patients were included: one in which patients underwent presurgical nasoalveolar moulding and one in which they did not. The nasolabial aesthetics were evaluated on two-dimensional photographs at 6 months post cheiloplasty. Cupid's bow, vermilion symmetry, vermilion notching, premaxillary show at rest, scar aesthetics, columella height, columella height, and bialar width were all significantly better in the nasoalveolar moulding group. Using the new scale, it was found that nasolabial aesthetics at 6 months post cheiloplasty were significantly better in patients who had undergone nasoalveolar moulding in infancy.
