Orbital process of palantine

What is the pterion
Area at which the frontal, parietal, temporal and sphenoid meet
What artery is susceptible to rupture from a blow to the side of the head

What are buttresses ?
Strong parts of skull unlikely to fracture
Briefly describe Le Fort 1 fractures
Transverse fracture of maxilla above upper lip (moustache fracture)
Explain Le Fort 2 fractures
Transverse upper nasal And frontal bone fracture,
Vertical bi lateral maxillary fractures lateral to nose under orbit
Le Fort 3 fractures
Transverse fracture from upper zygomatic bone lateral to orbit through to the same bone on the contra lateral side
(Passes through upper orbit)
May also be crush or vertical fractures of zygomatic arch
What is the dental formula
2,1,2,3
Define septoplasty
Any repair of the septum
Define rhinoplasty

What is the purpose of the nasal conchas
