Several surgical techniques have been proposed over the years for the treatment of maxillary deficiency aiming at correcting it efficiently, with long-lasting results and low morbidity. Surgically assisted rapid maxillary expansion has found wide acceptance for the treatment of maxillary deficiency in both adolescents and adults. Controversy still remains regarding particularly to which osteotomies are to be done in order to achieve satisfactory outcomes. The author reports on the results of the ortho-surgical maxillary expansion with osteotomies of the maxillary lateral walls and midpalatal suture. Seventeen adults with transverse maxillary deficiency had conventional CT scans and maxillary dental models prior to the operation and also after at least three months from the complete activation and stabilization of the expansion device. The measurements made before and after the operation as well as the final results were assessed and statistical analysis performed. All nineteen patients had the amount of expansion which had been planned. However, the amount of expansion in the molar region was shown to be statistically larger at the teeth while the results at the canines was similar in the three maxillary regions. When comparing the canine and molar regions, the intercanine expansion was greater at the palate foramina region and the opposite was observed with greater intermolar expansion within the regions of the alveolar process and dental.
