Purpose: The aim of this clinical Study was to analyze the Outcome, complications, and long-term results of transpalatal distraction for the correction of maxillary transverse deficiency (MTD) and assess skeletal and dental changes in the sagittal, vertical, and transverse planes through cephalograms and dental casts. Patients and Methods: Ten adult patients with MTD were treated with a Transpalatal Distractor (Surgi-Tec, Bruges, Belgium). Lateral and posteroanterior cephalometric films and dental casts were taken before surgery and at the end of the consolidation period. The statistical analysis of cephalometric film and dental cast measurements was undertaken with paired t tests. Results: The intraoperative and postoperative problems encountered were damage to the central incisive teeth as a result of vertical osteotomy, Wound dehiscence after the latent period, pain during the distraction period, and loosening of the distractor and buccal displacement of the left alveolar segment during the consolidation period. Model analysis showed that the greatest amount of transverse increase was in the premolar region (7.07 film for first premolar and 7.10 mm for second premolar). Frontal cephalometric analysis indicated that transverse distances increased more at the alveolar level (7.75 mm) than in the maxillary base (5.25 mm) and nasal region (4.3 mm). The asymmetries between the left and right sides in both dental and skeletal expansions were statistically nonsignificant. The changes in the Sella-nasion-point A, Sella-nasion-point B, Sella-nasion and gonion-gnasion angles were statistically significant. Conclusions: According to the results Of this Study, transpalatal distraction was found to be a clinically effective technique for palatal expansion in adult patients with MTD. However, treatment planning and regular clinical follow-up visits are necessary for long-term clinical Success. (C) 2008 American Association of Oral and Maxillofacial Surgeons
