Abstract
PURPOSE: To analyze anatomical variations of the greater palatine canal (GPC) using cone beam computed tomography (CBCT) images. METHODS: This study included 110 CBCTs. Axial slices were used to determine the shape of GPC and the number of lesser palatine foramina (LPF). Sagittal slices were used to assess the shape of the GPC and the number of lesser palatine canals (LPCs). RESULTS: The most prevalent axial and sagittal GPC shapes were oval (46.36%) and hourglass (23.64%). Most GPCs presented one LPF (47.27%) and one LPC (90.91%). CONCLUSIONS: GPC anatomy is highly variable. CBCT is a useful tool for evaluating the anatomical variations of GPC.
