Answers:
Management of an auricular hematoma involves all of the following except.
A) Drain via incision of helical sulcus
B) Place a drain to prevent fluid from collecting
C) Dental roll/prolene dressing left in place x 4 weeks
D) Antistaphylococcal abx
E) Drain via incision of antihelical fold
An auricular hematoma can be drained via a helical sulcus or antihelical fold incision depending on location of hematomas. Abx should be used and a drain can sometimes be used to drain fluid. A dental roll with nonabsorbable suture should be used to apply pressure to the incision site however this dressing is only left in place 7-10 days.
The first branchial arch gives rise to the first 3 hillocks which become---,---,---. the second branchial arch gives rise to the second 3 hillocks which become ---,---,---.
1st branchial arch = tragus, helical crus and helix
2nd branchial arch = antihelix, scapha and lobule

Free Response Question:
At what temperature is sensory nerve conduction blocked? What is the treatment for frostbite?
Quick Facts:
Otitis Externa (aka swimmer's ear)
-Pathogens grow best in EAC when alkaline conditions present which often happens after retention of water.
-Trauma can induce infection (cerumen removal, presence of foreign body, scratching canal skin)
-Common pathogens: pseudo. Staph and strep can play a role as well.
-Present with severe otalgia, erythema, edema and purulent otorrhea.
-Treat by cleaning EAC w/ suction, topical abx and acetic acid drops.
-Use gauze wick if sever obstruction present.
