    Successful treatment of a keloid on the upper lip by trepanation and radiotherapy: a case report by Xianghui Li, Yong Wei, Zhuren Ruan, Gao Wei, Zhijian Yao

    Published 2025-12-01
    “…Traditional treatments, such as intralesional injections, laser therapy, and surgical excision, have shown limited efficacy and are associated with high recurrence rates.Materials and methods: In a recent case, a 19-year-old male with a keloid on the upper lip did not respond to local injections of triamcinolone acetonide (TAC) or carbon dioxide ablative fractional resurfacing laser therapy.Results: A combined treatment approach involving trepanation and superficial radiotherapy successfully flattened the keloid tissue, with no recurrence observed during a 3-year follow-up period.Conclusions: This case underscores the potential efficiency and safety of combined therapeutic interventions and contributes valuable evidence towards the development of novel treatment strategies for keloids.…”
