Overview


A preauricular sinus is a small birth defect. It is a tiny tube that opens just before the ear. It may occur in front of one or both ears. It is a trait that can be passed through families or can occur as a random error in embryonic development (i.e., development of a baby in the womb). The preauricular sinus may cause no symptoms, however it can become infected. Treatment of the infected sinus may involve antibiotics and/or surgical removal.
