PPF and ITF

Question 1

boundaries of PPF

Answer 1

medial - lateral aspect of perpendicular plate of palatine bone
lateral - pterygomaxillary fissure
anterior - posterior wall of maxilla
posterior - pterygoid plates of sphenoid
roof - greater wing of sphenoid
floor - narrowing to palatine canals and pyramidal process of palatine bone

Question 2

openings of PPF (6)

Answer 2

foramen rotundum - CN V2, cavernous sinus
palatovaginal canal - pharyngeal branch of CN V2, naospharynx
pteyrgoid canal - nerve to pterygoid canal, middle cranial fossa
sphenopalatine foramen - sphenopalatine artery (3rd part maxillary), nasopalatine nerve CN V2, posterior superior nasal nerve, nasal cavity
infraorbital fissure - zygomatic nerve CN V2, inferior ophthalmic vein, infraorbital vessels, orbit
pterygomaxillary fissure - 3rd part of maxillary artery, ITF
pterygopalatine canal - greater and lesser palatine nerve CN V2

Question 3

contents of PPF (5)

Answer 3

pterygopalatine ganglion
CN V2
nerve to pterygoid canal 
3rd part maxillary artery 
infraorbital vein

Question 4

boundaries of ITF

Answer 4

medial - lateral pterygoid plate
lateral - coronoid process and ramus of mandible
anterior - superiorly the inferior orbital fissure, inferiorly the posterior wall of maxilla
posterior - styloid process sheath
roof - inferior surface of greater wing of sphenoid and squamous part of temporal bone
floor - medial pterygoid muscle
inferior - no physical boundary so route of infection

Question 5

openings of ITF (3)

Answer 5

foramen ovale - CN V3
foramen spinosum - middle meningeal artery
pterygomaxillary fissure

Question 6

contents of ITF

Answer 6

lateral and medial pterygoid muscles
pterygoid venous plexus/ maxillary vein
1st and 2nd parts of maxillary artery 
middle meningeal branch of maxillary artery/ vein
otic ganglion
chorda tympani CN VII 
CN V3
CN IX
