The majority of preauricular sinuses do not cause symptoms or problems, but some become symptomatic due to infection, discharge or abscesses. Once there is an infection, systemic antibiotics are needed. If an abscess is present, it needs to be incised and drained. There are differing opinions in the medical literature about the indications for surgical removal of preauricular sinuses. Some believe that even asymptomatic sinuses should be removed. Others believe that surgery is indicated if infection or another complication arises; after an infection, the likelihood for recurrent infections is high.
