Abstract: Background: Maxillary advancement may affect speech in cleft patients. Aims: To evaluate whether the amount of maxillary advancement in Le Fort I osteotomy affects velopharyngeal function (VPF) in cleft patients. Methods: Ninety-three non-syndromic cleft patients (51 females, 42 males) were evaluated retrospectively. All patients had undergone a Le Fort I or bimaxillary (n = 24) osteotomy at Helsinki Cleft Palate and Craniofacial Center. Preoperative and postoperative lateral cephalometric radiographs were digitized to measure the amount of maxillary advancement. Pre- and postoperative speech was assessed perceptually and instrumentally by experienced speech therapists. Student's t-test and ManneWhitney's U-test were used in the statistical analyses. Kappa statistics were calculated to assess reliability. Results: The mean advancement of A point was 4.0 mm horizontally (range: -2.8-11.3) and 3.9 mm vertically (range 14.2-3.9). Although there was a negative change in VPF, the amount of maxillary horizontal or vertical movement did not significantly influence the VPF. There was no difference between the patients with maxillary and bimaxillary osteotomy. Conclusions: The amount of maxillary advancement does not affect the velopharyngeal function in cleft patients.
