Anatomy

Question 1

Pterygopalatine fossa

Answer 1

Contents:
V2 maxillary
Maxillary artery & sphenopalatine artery going to nose
Pterygopalatine ganglion
Nerve and artery of pterygoid canal pass through *foramen lacerum

Borders:
Anterior: mx tuberosity
Posterior: lateral pterygoid plate
Separates maxillary and sphenoid bones

Question 2

Medial pterygoid

Lateral pterygoid

Answer 2

Medial pterygoid superior head: mx tuberosity
Medial pterygoid deep head: medial of lateral pterygoid
Lateral pterygoid superior head: greater wing of sphenoid
Lateral pterygoid deep head: lateral of lateral pterygoid
Pterygoid is part of the sphenoid.

Posterior to anterior:
Pterygoid plate - posterior pterygomaxillary suture - anterior pterygomaxillary fissure - mx tuberosity

Question 3

Jugal point is intersection of:

Answer 3

Mx tubersity and zygomatic buttress

Question 4

Bolton
Basion
Opisthion
Broadbent

Answer 4

Bolton: highest point on occipital condyle
Basion: anterior inferior border of foramen magnum
Opisthion: posterior inferior border of foramen magnum. Opisthion is NOT a bilateral structure.
Broadbent: intersection of line between N-Ba and sella perpendicular (fyi Facial Axis is NBa-PtGn)

The point most closesly associated with Opisthion: Bolton pt (closer than Basion)

Question 5

Sinus drainage:
Superior meatus
Middle meatus
Inferior meatus
Sphenoethmoidal recess

Answer 5

Superior meatus: posterior ethmoid
Middle meatus: frontal, anterior ethmoid, maxillary
Inferior meatus: nasolacrimal duct
Sphenoethmoidal recess: sphenoid
