nose and orbit landmarks

glabella

The slight elevation directly between the two orbits in the frontal bone. It is just above the base of the nose superior to the SOM.

Nasion

The central depression at the base of the nose it is formed by the point of which the frontal and nasal bones joint

Joins the forehead at the level of BSOM

Superciliary arch

Starts at the glabella and moves, superiorly and laterally above the central portion of the eyebrow. The central part lies superficially to the frontal sinuses on either side, informs the brow of the school.

Superior orbital margin

Rests just inferior to the eyebrow and are more pronounced on its lateral aspect the SOM forms the roof of the orbit, and serves as one of the points used to delineate the inferior border of whole brain fields when that part of the SOM is in the treatment field. The frontal part of the brain is also in the field.

Maxilla

Bone between the Ala of the nose and the prominence of the cheek

This bone house is the largest of the paranasal sinuses the inferior alveolar ridge of the maxilla house is the teeth sockets

Zygomatic bone

Forms the lateral aspect of the orbit and the prominence of the cheek articulation between the frontal process of the zygomatic bone, and the zygomatic process of the frontal bone can be palpitated in the lateral orbital margin

Lateral orbital margin

Bony landmark that forms the lateral border of the bony orbit

Midzygomatic point

A point midway between the EAM and the lateral canthus lies roughly at the floor of the sphenoid sinus and the roof of the nasal pharynx 1 cm superior to that point corresponds to the floor of the sella turcica in 1.5 cm superior to that point corresponds to the pituitary plant

acanthion

At the base of the nose, inferior to the tip

Superior to the lips

Inferior orbital margin

The lower border of the orbit

Medial orbital margin

Extremely difficult to palpate, and therefore is not clinically useful as an atomic landmark it does have some usefulness radiographically

Medial to the inner canthus

Inner canthus

A soft tissue landmark that is formed at the junction of the upper and lower eyelids at the medial aspect of the eye

Outer canthus

A soft tissue landmark that is formed at the junction of the upper and lower eyelid at the lateral aspect of the eye

Punctum lacrimae

A soft tissue landmark that can be used as a point of reference in the surface anatomy of the eye this white appearing section of the eye lies just next to the I see on the lower eyelid. Tears are drained through this duct into the lacrimal duct.

Lateral ala nasi

A soft tissue landmark formed by the lateral attachment of the ala nasi with the cheek

Inferior Ala nasi

A soft tissue landmark formed by the inferior attachment of the Ala nasi with a cheek

Ala nasi

Wing portion of the nose

Dorsum of the nose

Bridge of the nose that extends from the glabella to the tip of the nose

Buccal mucosa

Mucus membrane lining the inner cheeks and lips forming part of the oral mucosa

Vermilion surface

The surface of the lips

Retromolar trigon

A small triangular area of moxa located behind the third mandibular, molar, wisdom teeth it serves as a transition zone between the oral cavity and the oral fairings

Commissure of the mouth

Is formed at the junction of the upper and lower lip. This landmark is extremely mobile.

Gingival Ridge floor of mouth

The soft tissue area located under the tongue extending from the inner surface of the lower gingiva to the underside of the tongue

Lingual frenulum

A small flexible band of tissue under the tongue that anchors it to the floor of the mouth, supporting stability for speaking, swallowing and eating

Columella

Is it located at the junction of the skin of the nose with the skin of the face at the superior end of the Philtrum

mucocutaneous junction

Is located at the junction of the Vermilion border of the lip with the skin of the face
