Preauricular Sinus

Preauricular Sinus is a common congenital malformation characterised usually by a dimple near the external auditory canal. Most of them are asymptomatic and not treated unless they get repeated infections.

Preauricular Sinus can have some clear or whitish discharge even when it is not infected. In this case , just keep the area clean by washing with soapy warm water.
If there are signs of infection: pain, fever, pus discharge: meet a doctor and antibiotics are needed.
If abscess, then incision and drainage is required.
If a preauricular Sinus is getting infected repeatedly or abscess is drained, then a definitive decision of Sinus is planned in 8–12 weeks.
