Preauricular sinus/cyst is a common congenital malformation, which presents as a pit at the anterior margin of the ascending margin of helix. It is inherited disorder. It is closely related to the helical cartilage.
The standard technique for excision involves an elliptical incision around the sinus opening and dissecting out the tract.The use of methylene blue or a probe may aid in the dissection. There is a great chance of leaving epithelial remnants behind that lead to recurrence.
