Purpose: Keloids are serious scars that often extend beyond the borders of the original wound. They are difficult to cure because of their high recurrence rate, particularly in large keloids that require skin grafts. Keloid mass resection and post-operative radiotherapy is an effective method in keloid treatment. But skin graft in large keloid may impose many obstacles in post-operative radiotherapy. We use pre-radiotherapy to solve this problem.
Methods: Eighty-six patients with chest wall keloids were treated from April 2005 to December 2015. The patients were treated with the pre-cut and pre-radiotherapy method. As for keloid pre-cut surgery, an incision was made down to the subcutaneous layer around the edge of the keloid. The wound was then closed after coagulation. 900cGy radiotherapy was applied on the following day. Then, the keloid was removed, and the wound was closed with a skin graft. Another 900cGy radiotherapy was applied when the graft was found to have survived. The patients received follow-up examinations at 6 and 24 months post-surgery. The scar at the operation site and aesthetic satisfaction were recorded and analyzed.
Results: Keloid recurred in eleven patients in 6 to24 months follow-up time. The overall recurrence rate was 12.79%. Six of them were cured by the second time keloid scar resection and radiotherapy. Hypertrophic scar was observed in two patients. The scar resumed after 8 to 13 months garment pressure treatment. Four patients complained of local pruritus. Their symptoms disappeared gradually. The other patients achieved satisfactory results with no recurrence
Conclusion: The pre-radiotherapy with keloid edge pre-cut may be a promising treatment option for patients with large keloids that require skin graft operations.
