    Abstract:
    BACKGROUND: Repair of unilateral cleft lip and nasal deformity in three dimensions requires anticipation of changes in the fourth dimension that can be determined by periodic and objective assessment. METHODS: Fifty patients with unilateral cleft lip with or without cleft palate underwent primary repair from 1999 to 2004 and were followed through 2014. Anthropometry was performed immediately postoperatively and at a first and second follow-up interval, occurring at an average age of 6.6 and 11.5 years, respectively. Measured differences between cleft and noncleft sides included heminasal width (subnasale-alare), cutaneous labial height (subnasale-crista philtri inferior, subalare-crista philtri inferior), and transverse labial width at the cutaneous-vermilion border (crista philtri inferior-chelion). Contrasts for the rates of growth were assessed with t tests for correlated measures. Using the same method, the difference between growth on cleft and noncleft sides in the second period was compared to that in the first period. RESULTS: Heminasal width remained narrower on the cleft side, but this difference decreased over time. Subnasale-crista philtri inferior remained longer on the cleft side; there was no difference between the rate of growth on the cleft and noncleft sides in the second period. Subalare-crista philtri inferior remained shorter on the cleft side by a consistent difference at both times of follow-up measurements. Transverse labial width at the cutaneous-vermilion border remained shorter on the cleft side, but this difference decreased in the second period. CONCLUSION: Understanding how nasolabial features change with growth is critical to crafting the initial repair of unilateral cleft lip and nasal deformity. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.
