Treatment for auricular hematoma is twofold. Many of these individuals are on some medication which impairs coagulation. The use of aspirin, nonsteroidals or other anticoagulants should be discontinued. The auricular hematoma can often be drained by needle aspiration. This is easy to do and as long as it does not reaccumulate, is all that is required.
Infection is always a risk.
The ear should therefore be swabbed with alcohol or povidone-iodine. A small amount of lidocaine with adrenaline should be injected into the epithelium and then using a 10 or 20 cc syringe with an 18 gauge needle, the hematoma should be evacuated. The ear should then be observed for a short period of time. If the hematoma does not reaccumulate, the patient is sent home and advised to remain at rest for 24 hours. If one is skilled at applying a mastoid type pressure dressing, this may be beneficial.
