Anatomical terms of bone

In thehuman mouth, theincisive foramen (also known as: "anterior palatine foramen", or "nasopalatine foramen") is the opening of theincisive canals on thehard palate immediately behind theincisor teeth. It gives passage to blood vessels and nerves. The incisive foramen is situated within the incisive fossa of themaxilla.

The incisive foramen is used as ananatomical landmark for defining the severity ofcleft lip and cleft palate.

The incisive foramen exists in a variety of species.

Structure

[edit]

The incisive foramen is a funnel-shaped opening in the bone of the oralhard palate representing the inferior termination of theincisive canal.[citation needed] An oral prominence - the incisive papilla - overlies the incisive fossa.[1]

The incisive foramen is situated immediately behind theincisor teeth, and in between the twopremaxillae.[citation needed]

Contents

[edit]

The incisive foramen allows for blood vessels and nerves to pass. These include:

Clinical significance

[edit]

As many nerves exit theincisive canal at the incisive foramen, it may be used for injection oflocal anaesthetic.[3]

Whenplain radiographs are taken of themouth, the incisive foramen may be mistaken for a periapical lesion.[5]

The incisive foramen can be used as a landmark when describingcleft lip and cleft palate, which can either extend in front of (primary) or behind (secondary) the foramen.[6][7] It is also important as asurgical landmark to avoid damaging its nerves and vascular structures.[3]

History

[edit]

The incisive foramen is also known as the anterior palatine foramen,[5] the nasopalatine foramen, and the incisive fossa.

Other animals

[edit]

In many other species, the incisive foramina allow for passage of ducts to thevomeronasal organ.[2] It can be found incats,[6] andalligators.[8]
