The influence of different types of hard-palate closure in two-stage palatoplasty on maxillary growth: cephalometric analyses and long-term follow-up.

Using cephalometric analysis we investigated the influence on maxillary growth of two different types of hard-palate closure in two-stage palatoplasty. In 12 patients with complete unilateral cleft lip, alveolus, and palate, the lip and soft-palate were closed between 3 and 7 months of age. These 12 patients were then assigned to two groups of 6. In one group the hard palate was closed at 1 year 5 to 11 months of age by a vomer flap with a skin graft (VF group, Osada's two-stage palatoplasty) and in the other group it was closed by the mucoperiosteal pushback procedure (PB group). Sella-nasion-point A (SNA) in the VF group at 3 to 4 and after 10 years of age were within normal range and significantly larger than in the PB group. Two patients in the PB group required orthognatic surgery to obtain normal occlusion and a well-balanced profile. We concluded that in two-stage palatoplasty better maxillary growth can be obtained using the vomer flap method than using the pushback procedure.
