sphenoidal

The sphenoidal and posterior fontanelles close during the first few months of life.

Two sphenoidal conchae are situated at the anterior and posterior part of the body.

This mineral is orthorhombic and sphenoidal, exhibiting symmetry on 222.

On either side of the crest is an irregular opening leading into the corresponding sphenoidal air sinus.

The superior border supports the orbital process in front and the sphenoidal process behind.

Deep pain behind the eyes or headache in the back of the head may mean an infection in the sphenoidal sinuses.

The orbital and sphenoidal processes are separated from one another by the sphenopalatine notch.

Sphenoidal fissure: separates the wings and the body of the sphenoid bone.

This border is continuous above with the sphenoidal process; below it expands into the pyramidal process.

M1: The sphenoidal segment, so named due to its origin and loose lateral tracking of the sphenoid bone.

The zygomatic articulates with four bones: the frontal, sphenoidal, temporal, and maxilla.

Though the sphenoidal emissary foramen is small and variable, it is consistently symmetrical.

There is also evidence to show that the sphenoidal sinus may extend into the occipital bone after the age of twenty-five (Dutra, 1944).

It lies posterior and superior to the superior concha into which the sphenoidal sinus opens.

Surgical drainage with sphenoidotomy is indicated if the primary site of infection is thought to be the sphenoidal sinuses.

The sphenoidal sinuses are present as minute cavities at the time of birth (Onodi), but do not attain their full size until after puberty.

In a study conducted under 100 skulls, the sphenoidal emissary foramen was only present in 17% of the cases, and it was always single.

The sphenoidal angle, thin and acute, is received into the interval between the frontal bone and the great wing of the sphenoid.

An aperture of variable size exists in the anterior wall of each, and through this the sphenoidal sinus opens into the nasal cavity.

Thus, for the usually symmetric sphenoidal emissary foramina, asymmetry is more likely the result of a pathologic process than a normal variant.

To the sphenoidal spine are attached the sphenomandibular ligament and the tensor veli palatini muscle.

More rarely it opens on both surfaces, and then communicates with the posterior ethmoidal cells and the sphenoidal sinus.

The sphenoidal process of the palatine bone is a thin, compressed plate, much smaller than the orbital, and directed upward and medialward.

At the time he referred to the condition as "sphenoidal fissure syndrome", later to be known as "Rochon-Duvigneaud's syndrome".

Other than the anterior and posterior fontanelles, the mastoid fontanelle and the sphenoidal fontanelle are also significant.
