Clinical Effect of Dermatologic Trephination Combined With Radiotherapy in the Treatment of Keloids.

Abstract

Keloids are excessive formations of scar tissue that develop at the site of a skin injury. Due to their invasive nature, they have a negative impact on the skin's appearance and are prone to recurrence, making them a challenging condition to treat in terms of skin aesthetics. The objective of this article is to compare the long-term effects of dermatologic trephination with non-surgical treatments in scar repair and evaluate their clinical value. A retrospective analysis was conducted on 48 patients who received keloids treatment in the Department of Dermatology and Thoracic Surgery of our hospital from January 2021 to October 2023, of which 24 patients received dermatologic trephination and 24 patients received non-surgical treatment. Outcome measures included scar appearance, scar healing time, pain and itching levels, and patient satisfaction. In the comparison of scar healing time, the healing time of patients using dermatologic trephination was significantly shorter than that of patients in the non-surgical group. In the evaluation of the degree of itching, the degree of itching in patients undergoing dermatologic trephination was significantly lower than that of patients in the non-surgical group. In the evaluation of satisfaction, the satisfaction of patients using dermatologic trephination was significantly higher than that of patients in the non-surgical group. This study demonstrates that trephination achieves more significant long-term results in keloid revision, including improved keloid appearance, itching and patient satisfaction.
