The glabella is an important landmark when designing forehead and nasal prostheses. It is located:
Answer: On the frontal bone, between the superciliary arches above the nasion
The glabella is the smooth, slightly projecting area of the frontal bone between the two superciliary arches, superior to the nasion.
Which anatomical feature of the temporal bone serves as a key retention site for implant-retained auricular prostheses?
Answer: Mastoid process
The mastoid process of the temporal bone provides dense cortical bone ideal for osseointegrated implant placement to retain auricular prostheses.
The subnasale landmark, used in nasal prosthetic margin design, is defined as:
Answer: The midpoint of the base of the nasal septum where it meets the upper lip
Subnasale is the craniometric point at the midpoint of the angle between the nasal septum and the philtrum at the base of the nose.
In orbital anatomy, the term 'orbital rim' refers to:
Answer: The four-sided bony margin encircling the orbital opening, formed by frontal, zygomatic, and maxillary bones
The orbital rim is the quadrilateral bony margin forming the opening of the orbit, contributed by the frontal, zygomatic, and maxillary bones.
The nasolabial fold is a clinically significant surface landmark for prosthetic margin placement because it:
Answer: Serves as a natural color transition zone useful for hiding prosthetic edges
The nasolabial fold provides a naturally shadowed crease that can camouflage prosthetic margins, improving esthetic integration.
The Frankfort horizontal plane, used in craniofacial analysis, passes through:
Answer: The superior border of the external auditory meatus (porion) and the inferior orbital rim (orbitale)
The Frankfort horizontal plane connects the porion (uppermost point of the external auditory meatus) to the orbitale (lowest point of the inferior orbital rim).
During prosthetic ear fabrication, the anaplastologist notes the concha of the auricle. The concha is:
Answer: The deep central bowl-shaped depression leading to the ear canal
The concha is the large, deep, cup-shaped cavity at the center of the auricle that funnels sound toward the external acoustic meatus.
