MAX-FACE - ENT - OPHTHO Flashcards
Sign we see on lateral neck XR for epiglottitis?
AP neck XR for croup?
Epiglottitis = thumb print
Croup = steeple
Sudden onset 12-24 hours. Do not assess pharynx - nothing in mouth. Treatment non-invasive initially - overstimulating may cause respiratory distress
Epiglottitis
Usually idiopathic and unilateral.
Uveitis / Iritis (color)
What happens if you shine a light in the unaffected eye in a patient with uveitis/iritis?
What does slit lamp show?
Causes pain in affected eye due to consensual construction of irritated iris.
Slit lamp shows inflammatory cells in anterior chamber.
What happens in glaucoma?
What may result due to optic nerve damage and decreased retinal circulation?
What is the definitive treatment?
Junction b/t iris and cornea becomes narrowed/blocked
Blindness
Iridotomy
S&S of glaucoma (4)
-Sudden onset of unilateral eye pain
-blurry vision with halos
-hazy cornea
-IOP 40-80 (normal 20)
This causes sudden onset of vision loss, although the patient can still see light. May be proceeded by amaurosis fagax.
Retinal Artery Occlusion
Temporary vision loss for seconds to minutes that resolves. Essentially a TIA of the eye.
Amaurosis Fugax
Vision threatening emergency! Can be degenerative or from trauma.
Retinal Detachment
What happens in retinal detachment?
Separation of retinal layers from choroid, causing retinal ischemia.
S&S of retinal detachment (3)
-“curtain coming down”
-floaters
-cloudy vision
Ocular emergency due to penetrating trauma. Usually causes a “teardrop” iris. Tx is to patch both eyes.
Globe Rupture
What symptom do we normally see with a globe rupture?
“Teardrop” iris
These types of facial fractures occur from forceful impact to face. Transversely disrupts nasomaxillary and zygomaticmaxillary bony facial buttresses.
LaFort Fractures
Type of LaFort Fracture: horizontal alveolar ridge; causes swelling of upper lip, buccal surface bruising, malocclusion, loose teeth
LaFort Type 1
