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.

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.
