- Abstract
- Preauricular sinuses are common congenital malformations that usually occur at the anterior margin of the ascending limb of the helix. There are rare cases in which the location of the preauricular sinus is posterior to the tragus, and the direction of the sinus tract is toward the posterior. This variant type of preauricular sinus is called, 'postauricular sinus'. Postauricular sinus is uncommon. Thus, diagnosis and treatment may be delayed due to its location of its opening and atypical clinical symptoms. Typical treatment is a single stage operation through bidirectional skin incision. However, we found out that according to the length and invasion depth of the sinus tract, there was an option between unidirectional and bidirectional skin incisions that we may choose from.
