Background: Keloid scars occur idiopathically, and the ear is a common site of keloid scar formation after ear-piercing. Management is always challenging because of the high likelihood of recurrence. When treating a large keloid scar, surgical debulking is inevitable. Among various surgical options, the fillet flap is useful for very large scars with broad stalks that cannot be removed by simple excision and primary closure.
Methods: From April 2016 to June 2021, scar revision with a fillet flap was performed on 24 auricular keloid scars. The operation was performed to debulk the scar as much as possible, while retaining a thin envelope of scar tissue. The patients were observed for 1 year postoperatively. Oral tranilast (a transforming growth factor-β suppressor) was administered to reduce the risk of recurrence during follow-up. When recurrence was observed, triamcinolone was injected into the scar.
Results: All 24 cases were successfully treated without major problems such as flap loss. The postoperative contour and volume of the scars were appropriate when recurrence did not occur. During the follow-up period, there were nine cases of keloid recurrence, and the mean number of triamcinolone injections was 2.7. One patient experienced a second recurrence 10 months after the first recurrence and needed two more injections.
Conclusion: The fillet flap is an appropriate option for removing a large keloid scar with a broad stalk. Although it does not guarantee that recurrence will not take place, it provides a small and flat scar into which triamcinolone can be injected if the keloid scar recurs.
