Anatomy Flashcards
The buccal fat pad consists of a main body and what extensions?
The buccal fat pad consists of a main body and the four extensions
- Buccal
- Pterygoid
- Superficial temporal
- Deep temporal
As the buccal fat pad wraps around the posterior aspect of the maxilla, it travels through the pterygomaxillary fissure and is in intimate contact with ___artery and the ___division of the trigeminal nerve
Internal maxillary artery and the maxillary division of the trigeminal nerve
How far anterior does the buccal fat pad extend
a) first molar
b) first premolar
c) second premolar
d) second molar
A) First molar - the buccal fat pad extends to roughly the first molar anteriorly
In the maxillary vestibular approach, how far superior to the mucogingival junction should the incision be placed?
3 to 5 mm super to the mucogingival junction. Leaving unattached mucosa on the alveolus facilitates closure
The posterior edge of the nasal floor is approximately ___mm posterior to the piriform aperture
The posterior edge of the nasal floor is approximately 45mm posterior to the piriform aperture
What type of epithelium is the frontal sinus covered with and how thick is it?
The frontal sinus is covered with pseodustratified ciliated respiratory epithelium and is roughly 0.07 to 2.0 thick
At what rate does mucin empty from the frontal sinus
Mucin empties from the frontal sinus at roughly 5.0g/cm2
What type of bone is the frontal bone?
The frontal bone is an intramembranous bone
At what age does the metopic suture close?
The metopic suture closes at roughly 2 years of life
At what age does secondary pneumatization of the frontal sinus begin and at what age is most of the pneumatization completed. Finally, when does pneumatization stop?
Secondary begins between 6 months and 2 years. It is mostly complete by 12-16 years, but continues until age 40.
At what age is the frontal sinus radiographically identifiable?
6 years of age
What is the average height and width of the frontal sinus?
Height of frontal sinus is 32mm
Width of frontal sinus is 26mm
What meatus does the frontal sinus drain into?
The frontal sinus drains into the wth lid sit cells of the middle meatus
The NOE region is supported by three buttresses, what are they?
1 vertical buttress, the frontomaxillary buttress
2 horizontal buttresses, the Supraorbital and infra orbital rims
Through which foramen does the nasociliary nerve pass? What is the vascular structure that accompanies this nerve?
Anterior ethmoidal foramen with the anterior ethmoidal artery
