Abstract:
Objective:To assess clinical efficacy of micro-punch combined with electron beam radiation for the treatment of keloids on the lower jaw.Methods:Clinical data were collected from 36 patients with keloids on the lower jaw, who received micro-punch combined with electron beam radiation at Department of Dermatology, Xijing Hospital, the Fourth Military Medical University from January 2018 to January 2019, and analyzed retrospectively. There were 16 males and 20 females, with an average age of 23.80 years and a median disease duration of 32 months. The severity of keloids was evaluated before and 12 months after operation. A paired t test was used to compare keloid severity scores before and after treatment. Results:All of the 36 patients experienced primary wound healing. The keloid severity score was 7.11 ± 1.46 before operation, and significantly decreased to 2.33 ± 0.47 at 12 months after operation ( t=13.85, P=0.008) . Twelve months after the treatment, 15 patients were cured, 17 showed marked improvement, and 4 showed no response or experienced recurrence within 12 months after treatment, with a response rate of 88.89%. Conclusion:Micro-punch combined with electron beam radiation is effective for the treatment of keloids on the lower jaw.
