OBJECTIVE: To assess the effect of two palatoplasty procedures, modified Furlow's palatoplasty (F procedure) and modified two-flap palatoplasty (T procedure), on the maxillofacial morphology of unilateral cleft lip and palate (UCLP) and bilateral cleft lip and palate (BCLP) during the primary dentition period.
DESIGN: Retrospective cohort study.
SETTING: Department of Orthodontics, School of Dentistry, Showa University.
PARTICIPANTS: We enrolled 106 pediatric patients (63 boys, 43 girls; aged 4.43 ± 0.34 years) with non-syndromic orofacial clefts who underwent cheiloplasty and palatoplasty.
INTERVENTIONS: Patients were divided into four groups according to cleft type (BCLP or UCLP) and palatoplasty procedure type (F or T procedure).
MAIN OUTCOME MEASURES: Maxillofacial morphology was assessed by examining parameters on lateral cephalograms.
RESULTS: Multiple comparisons revealed significant differences among N-A, N-ANS, and ANS-PNS distances and SNA and ANB angles among the groups. There were significant differences in N-A, N-ANS, ANS-PNS, SNA, and SNB among the UCLP and BCLP groups. The calculated effect sizes were all within 0.3-0.5. The statistical power was as follows: N-A, 86.41%; N-ANS, 79.77%; ANS-PNS, 97.49%; SNA, 96.88%; and ANB, 99.25%.
CONCLUSIONS: Although UCLP and BCLP both exhibited differences in craniofacial distances and angles, the procedure type (either F or T procedure) had no significant effect on the maxillofacial morphology (as determined by lateral cephalograms). However, to rule out additional bias, patient-specific factors should be considered that may be affected by maxillofacial development when deciding surgical approaches.
