nasofrontal

A true nasofrontal duct only exists in 15% of the population.

The nasofrontal duct is a duct connecting the infundibulum and frontal sinus.

Encephaloceles are generally classified as nasofrontal, nasoethmoidal, or naso-orbital, however, there can be some overlap in the type of encephalocele.

The nasofrontal vein is a vein in the eye which drains to the superior ophthalmic vein.

Larger craniofacial osteomata may cause facial pain, headache, and infection due to obstructed nasofrontal ducts.

Prokinesis, which occurs between the braincase and facial skeleton (the nasofrontal joint, or within the nasals), e.g. birds.

Possible explanations for this might be the relatively long and delicate nasofrontal duct that connects the narrow frontal recess with the frontal sinuses.

Abel suffered from a rare nasofrontal facial encephalocele, an extreme protrusion of brain tissue from the front of his skull.

The nasal projection measurement is obtained by delineating a right triangle with lines parting from the nasion (nasofrontal juncture) to the alar-facial-groove.

These fractures start at the nasofrontal and frontomaxillary sutures and extend posteriorly along the medial wall of the orbit through the nasolacrimal groove and ethmoid bones.

The nasofrontal angle, between the frontal bone and the nasion usually is 120 degrees; the nasofrontal angle is more acute in the male face than in the female face.

At the base of the upper mandible a thin sheet of nasal bones is attached to the skull at the nasofrontal hinge, which gives mobility to the upper mandible allowing it to move upwards and downwards.

It receives the external nasal veins of the ala of the nose, and communicates with the superior ophthalmic vein through the nasofrontal vein, thus establishing an important anastomosis between the anterior facial vein and the cavernous sinus.

The superior ophthalmic vein begins at the inner angle of the orbit in a vein named the nasofrontal which communicates anteriorly with the angular vein; it pursues the same course as the ophthalmic artery, and receives tributaries corresponding to the branches of that vessel.

The facially proportionate projection of the nasal tip (the distance of the nose's tip from the face) is determined with the Goode Method, wherein the projection of the nasal tip should be 55-60 per cent of the distance between the nasion (nasofrontal junction) and the tip-defining point.
