Last week I showed the superior foramina of the nasopalatine canal and this week is the inferior foramen; the incisive foramen. The incisive foramen presents as a round to ovoid radiolucent entity between the maxillary central incisors. When the width of the incisive foramen is 10 mm (1 cm) or larger a nasopalatine canal cyst should be considered.

Left – yellow circle showing the incisive foramen.
Right – incisive foramen as an ovoid radiolucent entity between the maxillary central incisors.


If you have any questions or comments about the incisive foramen, please leave them in the comments below. Thanks and enjoy!
