Study type | Observational [Patient Registry] |
The objective of this study is to evaluate the effect of bone-anchored rapid maxillary expansion (RME) in the volume of the right maxillary sinus, left maxillary sinus and nasal and maxillary sinus airway complex, through bone anchored maxillary expansion devices (BAME); in addition, the influence of gender and age in the volume changes will be also analyzed. Material and method: 18 patients between undergone RME treatment with a jackscrew based on 4 miniscrews which will be placed in the palate on both sides of the midpalatal suture. Cone-beam computed tomography (CBCT) scans will be taken before and after suture palatine expansion and datasets will be uploaded into therapeutic digital planning software to measure the volume (mm3) of the right maxillary sinus, left maxillary sinus (mm3) and nasal and maxillary sinus airway complex (mm3). The airway volumes will be isolated after selecting the anatomical area in the axial, coronal and sagittal space plane and ensuring the air density measurement by reference points placement inside the selected area. Statistical analysis between preoperative and postoperative measurements will be performed using the statistical analysis of the t-test.
