Considerazioni eziopatogenetiche anatomopatologiche e cliniche sulle cisti naso-palatine

The nasopalatine cyst (CNP) was the most common non-odontogenic cyst of the oral cavity, with a range of incidence that varies from 0,5% to 1%. Among the various aetiopathogenetic hypotheses, traumatic factors, bacterial infections, phenomena of retention to the occlusion of the mucous glands ducts are enumerated. The CNP is usually asymptomatic and, because of slow growth, it frequently represents a casual find in radiography. In the OPT the form usually appears round, ovoid; the radiography provide a cbaracteristic image of playing card heart in the cases in which the anterior nasal spine overlaps to the radiolucent defect determined by the cysts. In this work two clinical cases with clinical, radiological and histopathological characteristics typical of the CNP, are presented.
