What kind of blood is found in an Epidural Hematoma?
Arterial Blood
What shape does an Epidural Hematoma typically have?

Epidural Hematoma
What type of hematoma does NOT typically cross suture lines?
Epidural Hematoma

Subdural Hematoma
What kind of blood is found in a Subdural Hematoma?
Venous Blood
What shaped does a Subdural Hematoma typically have?
Crescent Shaped
Type of hematoma where since the brain is floating freely, bathed in CSF and can move in the skull, but the venous sinuses are fixed and the displacement of the brain that occurs in trauma such as fall can tear the bridging veins.

Thunderclap Headache
(Worst Headache of my Life)
Plexus that continues with the veins of the orbits, face and Cavernous Venous Sinus.
Pterygoid Venous Plexus
Veins that provides a direct route for infection from the orbit and face to the cavernous sinus
Ophthalmic Veins
Allows movement of the Pharynx, Esophagus, Larynx, and Trachea when swallowing.

What is clinically important about the Retropharyngeal Space?
Major Pathway for Infection
What closes the Retropharyngeal Space?

Carotid Sheath (Lateral)
Infection between the investing layer and muscular part of the pretracheal fascia surrounding the infra hyoid muscles, the infection usually does NOT spread beyond the manubrium of the Sternum.
Retropharyngeal Abscess
If an infection is between the Investing Fascia and Pretraceal Fascia, where might it spread to?
Thorax
(Mediastinitis)
Considered to be among the most serious of deep neck infections.
Retropharyngeal Abscess
