Definition: A nonodontogenic cyst that forms in the nasopalatine canal. This is commonly an incidental finding. This is also referred to as a nasopalatine duct cyst and/or an incisive canal cyst.
Radiographic Features:
Location: Anterior maxilla between apices of maxillary central incisors.
Edge: Well-defined. Corticated.
Shape: Round to ovoid. In the past, the nasopalatine canal cyst was referred to as having a ‘heart’ shape. This ‘heart’ shape was actually created by the superimposition of the anterior nasal spine at the superior aspect of the lesion. So while this term may still be thrown around, a nasopalatine canal cyst is not truly ‘heart’ shaped.
Internal: Radiolucent, unilocular
Other: A nasopalatine canal cyst should be considered when the size of the incisive foramen is enlarged greater than 1 cm. The lamina dura of the maxillary central incisors are intact indicating the lesion is not associated with either tooth. It may displace or resorb adjacent teeth as it enlarges.
Number: Single.
