The Variant type of Preauricular Sinus with Recurrent Postauricular Abscess: Excision by Single Incision Preauricular Approach

Abstract

The variant type of preauricular sinus often presents with recurrent postauricular abscess, and history of repeated operations or incision and drainage. A dual incision technique is generally utilized with one incision being made in the preauricular and the other in the postauricular area. We report 4 cases of a variant type of preauricular sinus with recurrent postauricular abscesses. All cases were managed with single incision preauricular approach under operating microscope. Dual incision may be required if there is a persistent skin defect or fistulous communication at postaural area. The single incision is a less invasive acceptable technique for excision of variant type of preauricular sinus.
