Craniofacial Anatomy & Landmarks Flashcards

Which cranial suture separates the two parietal bones at the midline?

Answer: Sagittal suture

The sagittal suture runs anteroposteriorly along the midline, separating the two parietal bones.

The nasion is defined as the junction of which anatomical structures?

Answer: Nasal bones and frontal bone

The nasion is the craniometric point at the intersection of the internasal suture and the frontonasal suture.

An anaplastologist designing an auricular prosthesis should identify the anatomical landmark known as the tragus. What is its location?

Answer: The small cartilaginous projection anterior to the ear canal

The tragus is the small, cartilaginous projection that partially covers the external acoustic meatus anteriorly.

Which bone forms the primary structure of the zygomatic arch?

Answer: Zygomatic bone and temporal bone

The zygomatic arch is formed by the zygomatic process of the temporal bone joining the temporal process of the zygomatic bone.

The philtrum is a surface landmark relevant to lip and nasal prosthetics. It is best described as:

Answer: The vertical groove between the nose and the cupid's bow of the upper lip

The philtrum is the midline vertical groove on the external surface of the upper lip, bounded superiorly by the base of the columella.

When fabricating an orbital prosthesis, the anaplastologist must consider the medial canthus. This landmark refers to:

Answer: The medial corner of the eyelid opening near the nose

The medial canthus is the inner corner of the palpebral fissure, located closest to the nose.

Which foramen transmits the supraorbital nerve and vessels, and is a palpable landmark used in facial prosthetics?

Answer: Supraorbital foramen (notch)

The supraorbital foramen (or notch) is located along the superior orbital rim and transmits the supraorbital nerve and artery.
