선천성 전이개누공의 임상

Background and Objectives: The aim of this study is to evaluate the clinical course of congenital preauricular fistula (PAF) and to know the important surgical tips for decreasing the recurrence after surgery. Materials and Methods: Seventy four operated cases with PAF were analyzed retrospectively. Fistula tracts were stained with gentian violet one day before surgery. All the procedures were done under microscope and the stained fistula tracts were removed completely above the temporalis muscle fascia. Results: The overall recurrence rate in this study was 1.4%. The average follow-up period was 3.5 years. Conclusion: Complete dissection of fistula tract above the temporalis muscle fascia using microscope is very important factor for the prevention of recurrence in PAF surgery.
