OBJECTIVE: Maxillary growth in patients with cleft lip and palate is highly variable. The authors' aim was to investigate associations between preoperative cleft lip measurements and maxillary growth determined cephalometrically in patients with complete unilateral cleft lip and palate (cUCLP).
DESIGN: Retrospective cross-sectional study.
PATIENTS: Children with cUCLP.
METHODS: Preoperative cleft lip measurements were made at the time of primary cheiloplasty and available for each patient. Maxillary growth was evaluated on lateral cephalometric radiographs taken prior to any orthodontic treatment and alveolar bone grafting (8.5 ± 0.7 years). The presence of associations between preoperative cleft lip measurements and cephalometric measures of maxillary growth was determined using regression analyses.
RESULTS: In the 58 patients included in the study, the cleft lateral lip element was deficient in height in 90% and in transverse width in 81% of patients. There was an inverse correlation between cleft lateral lip height and transverse width with a β coefficient of -0.382 (P = .003). Patients with a more deficient cleft lateral lip height displayed a shorter maxillary length (β coefficient = 0.336; P = .010), a less protruded maxilla (β coefficient = .334; P = .008), and a shorter anterior maxillary height (β coefficient = 0.306; P = .020) than those with a less deficient cleft lateral lip height.
CONCLUSIONS: Patients with cUCLP present with varying degrees of lateral lip hypoplasia. Preoperative measures of lateral lip deficiency are related to later observed deficiencies of maxillary length, protrusion, and height.
