Question 10

What are the total number of bones in the skull (excluding the auditory ossicles)?

Answer 10

22

Question 11

The maxillary bone (maxilla), zygomatic bone (malar bone), frontal bone, sphenoid bone, ethmoid bone, lacrimal bone all make up what?

Answer 11

the bones of the orbit

Question 12

What is a le fort I and II fracture?

Answer 12

partial fracture of normally fused bones of the skull

Question 13

What is a le fort III fracture?

Answer 13

complete dysjunction of normally fused bones of the skull

Question 14

What is this:
wide variety of horizontal fractures of the maxilla, passing superior to the maxillary alveolar process (i.e superior to the roots of the upper teeth) crossing the bony nasal septum sometimes the pterygoid plates of the sphenoid bone

Answer 14

Le Fort I fracture

Question 15

What is this:
Passes from the posterolateral parts of the maxillary sinuses and then superomedially through infraorbital structures, the lacrimal bones, the ethmoid bone, and up to the bridge of the nose. As a result, the entire
pyramidal-shaped central part of the face, including the hard palate and the maxillary alveolar processes, is separated from the rest of the cranium.

Answer 15

Le Fort II fracture

Question 16

What is this:
This is a severe horizontal fracture that passes through the superior parts of orbit and the ethmoid and nasal bones. It extends laterally through the greater wings of the sphenoid bone and the frontozygomatic sutures. Often, the zygomatic bones and the zygomatic arches are also fractured.
This is a complete cranio-facial
dysjunction.

Answer 16

Le Fort III fracture

Question 17

craniogacial dysjunction in le fort III fracture distorts (blank)

Answer 17

facial symmetry
