AIM: The aim of this prospective study was to evaluate the midpalatal suture in children submitted to rapid palatal expansion with computerized tomography. METHODS: The sample was comprised of 17 children aged between 5 years and 2 months and 10 years and 5 months, that were submited to rapid palatal expansion. The radiologic aspect of the sutures were evaluated through computerized tomography. RESULS AND CONCLUSIONS: The tomographic images showed that, after the retention phase (8 to 9 months post-expansion), the midpalatal suture was completely ossified from the anterior to the posterior nasal spine region.
