Fissural cysts of the palate

Abstract

Fissural cysts of the palate, whether median platine or nasopalatine, are of nonodontogenic origin and are located in the midsuture area of the hard palate. The difficulty in arriving at a definitive diagnosis is due to the fact that both the median palatine cyst and the nasopalatine cyst are located in the midsuture line of the hard palate. Whenever these cysts enlarge peripherally and/or involve adjacent anatomic areas, the radiographs demonstrate a large radiolucent area which extends beyond the characteristic boundaries of either the nasopalatine or median palatine cyst.
