“…Another possibility is that palatoplasty techniques influence maxillary growth as it is well recognized that the scar formation on the hard palate after pushback palatoplasty leads to growth retardation. [37][38][39][40] In contrast, a good anterior-posterior growth of the palate has been suggested after the 1-stage Furlow palatoplasty. 41 Eventually, in the ETS protocol both the technique and timing of surgery may work together to reduce the negative effects of surgery on maxillary growth.…”

Objective To examine skeletal morphology and dental arch relationships at 8 years of age following early 2-stage palatoplasty, which consists of soft palate plasty at 1 year of age and hard palate closure at 1.5 years of age, and to compare the results with those of conventional pushback palatoplasty. Design Retrospective. Setting Single institutional study. Patients Eighty-six patients with nonsyndromic complete unilateral cleft lip and palate (UCLP) were selected. Intervention The subjects were divided into 2 groups according to the palatoplasty protocols, as follows: 45 patients, who underwent early 2-stage palatoplasty (ETS group), and 41 patients, who underwent 1-stage pushback palatoplasty (PB group). Main Outcome Measures Skeletal morphology was assessed using lateral cephalometric analysis, and dental arch relationships were examined using the GOSLON yardstick. Results Cephalometric analysis revealed that the anterior-posterior length of the maxilla, measured by PTM-A and PTM-ANS, both projected to the nasal floor (NF) plane, was longer in the ETS group than in the PB group (PTM-A/NF, p = .04; PTM-ANS/NF, p = .03, unpaired t-test), although no significant difference was observed in SNA ( p = .09, unpaired t-test). Upper posterior facial height was shorter in the ETS group than in the PB group ( p = .02, unpaired t). Assessments with the GOSLON yardstick showed that the ETS group presented better dental arch relationships than the PB group ( p = 0.04, Mann–Whitney's U-test). Conclusions The present results suggested that the ETS protocol reduced the negative effects of palatal surgery on facial development and dental arch relationships in patients with complete UCLP at 8 years of age.
