High-resolution multislice computerized tomography with multiplanar and 3-dimensional reformation imaging in rapid palatal expansion.

Introduction: The purpose of this study was to evaluate whether high-resolution multislice computerized tomography (CT) with multiplanar reformation and 3-dimensional (3D) imaging is helpful in demonstrating the effects on midfacial sutures induced by rapid palatal expansion (RPE), thereby appraising and corroborating the current state of the art or possibly adding new findings.

Methods: Two patients in different stages of skeletal maturity (aged 10 and 16 years) underwent CT examinations immediately after active opening with the RPE appliance.

Results: The 3D CT imaging method proved to be valuable in visualizing skeletal effects on not only the midpalatal suture, but also adjacent sutures.
