Abstrakt:	Objective: Diminished maxillary growth is a consequence of labiopalatal repair, and many patients with cleft lip and palate require Le Fort I advancement. The goal of this study was to determine the frequency of maxillary hypoplasia as measured by need for Le Fort I. Subjects: Retrospective cohort study of males born before 1987 and females before 1989. Records of 173 patients with cleft lip and palate and 34 with cleft palate were reviewed. Methods: Documented age, gender, cleft type, and need for Le Fort I. Pearson chi-square and Fischer's exact analyses were performed to evaluate the frequency of Le Fort I. Results: Of 217 patients with cleft lip and palate or cleft palate, 40 were syndromic; of the remaining 177 patients, 69 had cleft lip, 78 had cleft lip and palate, and 30 had cleft palate. Thirty-seven of 177 patients (20.9%) required Le Fort I, subcategorized by cleft type: 0/69 for cleft lip, 37/78 for cleft lip and palate, and 0/35 for cleft palate (p<.0001). Of the 37/78 (47.4%) cleft lip and palate patients, the frequency of Le Fort I correlated with severity: 5/22 unilateral incomplete cleft lip and palate; 16/33 unilateral complete cleft lip and palate; 1/2 bilateral incomplete cleft lip and palate; 2/4 bilateral asymmetric complete/incomplete cleft lip and palate; 13/17 bilateral complete cleft lip and palate (p<.05). Conclusion: Overall frequency of Le Fort I was 20.9% in patients with cleft lip and palate and cleft palate. Of those with cleft lip and palate, 47.7% required maxillary advancement, but none with isolated cleft lip or cleft palate required correction. Frequency of Le Fort I osteotomy correlated with the spectrum of severity of labiopalatal clefting.
