The incisive foramen is a funnel-shaped opening in the bone of the oral hard palate representing the inferior termination of the incisive canal. [citation needed] An oral prominence - the incisive papilla - overlies the incisive fossa. [1] The incisive foramen is situated immediately behind the incisor teeth, and in between the two premaxillae.
The two incisive canals usually (in 60% of individuals) have a characteristic Y-shaped or V-shaped morphology: above, each incisive canal opens into the nasal cavity on either side of the nasal septum as the nasal foramina; below, the two incisive canals converge medially to open into the oral cavity at midline at the incisive fossa [1] as several incisive foramina.
The lesser palatine canals start from the greater palatine canal, and run with them, also opening into the roof of the oral cavity.Their openings are known as the lesser palatine foramina, and they transmit the lesser palatine artery, vein, and nerve, as well as the middle palatine vessels and nerve.
When the two maxillae are articulated, a funnel-shaped opening, the incisive foramen, is seen in the middle line, immediately behind the incisor teeth. In this opening the orifices of two lateral canals are visible; they are named the incisive canals or foramina of Stenson ; through each of them passes the terminal branch of the descending ...
Historically, the cause of nasopalatine duct cysts has been somewhat of an enigma. Although it was originally postulated that the cyst formed from trapped epithelial cells during embryonic fusion of the palatal bones, [3] it is now thought that it forms from oronasal ducts present within the incisive canals.

The incisive papilla is an oval [1] [2] midline mucosal [2] prominence of the anterior hard palate [1] overlying the incisive fossa. [1] [3] [2] It is situated posteriorly to the central incisors, [2] and represents the anterior extremity of the palatine raphe. [1] The incisive papilla marks the position of the foetal nasopalatine canal. [1]
