Summary A case is described in which exact localization of a cystic lesion associated with the apices of the maxillary central incisor teeth was sought to aid diagnosis and presurgical planning. The area was imaged using cross‐sectional tomographic slices in the sagittal plane produced by a Scanora® multimodal tomographic unit (Orion Corporation Soredex, Helsinki, Finland). The images demonstrated the cystic lesion arising within the incisive canal, confirming a diagnosis of naso‐palatine duct cyst. Surgery was therefore performed via a palatal approach giving direct access to the cyst. Histological examination of the enucleated cyst confirmed a naso‐palatine duct cyst.
