Study Notes

Jaw Bones

Upper jawbones are called maxillae.
Lower jawbone is referred to as the mandible.

Ear Anatomy

Tragus is the small, fleshy bulge located anterior to the ear canal.
Superficial temporal artery can be palpated just anterior to the tragus.
Mastoid process is approximately 1 inch posterior to the external ear opening.

Larynx and Cartilage

The Adam's apple is formed by the thyroid cartilage at the upper part of the larynx.
Cricoid cartilage is the only complete circular cartilage of the trachea.

Eye Structure

The eyeball itself is known as the globe.
Vitreous humor is a clear, jellylike fluid in the back of the eye that cannot be replaced if lost.
Sclera is the white part of the eye, while conjunctiva is the delicate membrane covering the inner eyelids and exposed eye surface.
Lacrimal gland produces fluid to keep the conjunctiva moist.

Pupil Function

The pupil is the opening in the center of the iris that allows light to reach the retina.
When light is shone into the pupil, it constricts in size.
Abnormal pupil size and reaction may indicate a brain injury.

Facial Trauma Considerations

Airway compromise is the most significant complication from facial injuries.
The facial skin and underlying tissues have a rich blood supply, leading to profuse bleeding.
EMTs must wear gloves and facial protection when handling open facial injuries.
Early identification and treatment of facial injuries are vital due to airway risks.
Significant facial trauma may increase suspicion for spinal cord injury.

Patient Care Procedures

In cases of massive facial trauma, suction the oropharynx as needed while stabilizing the head.
For active venous bleeding, apply direct pressure to the wound.
Communication about injuries is critical when transporting patients for specialized care.
Frequent reassessments of patients with neck or facial injuries are necessary due to respiratory impacts.

Eye Injuries Responses

Cover an injured eye without applying pressure when there is bleeding or major trauma.
Treat chemical splashes in the eyes by irrigating with water if no sterile saline is available.
Monitor for hyphema, which is bleeding in the anterior chamber of the eye.
A detached retina often presents with symptoms like flashing lights or floaters.

Nose Injuries

Anterior nosebleeds typically originate from the septum area and bleed slowly.
For nosebleeds, patients should lean forward and pinch their nostrils.

Miscellaneous

Minor ear injuries can be managed with padding between the ear and scalp.
For foreign objects in the ear, immediate transport to an emergency department is advised.
With traumatic eye injuries, it is crucial to manage both airway and fluid levels appropriately.
Direct pressure should be applied to neck lacerations that produce bright red spurting blood.
