Background Surgical removal is the primary method for clinical treatment of ear keloids. However, there are numerous surgical options available and no standardized approach in the literature. Objectives The aim of this study was to evaluate the impact of five-blade core excision on the removal of ear keloids. Methods A preliminary study involving 11 patients (21 lesions) with ear keloids was conducted between January 2023 and December 2023. Five-blade core excision was performed; superficial electron beam radiotherapy was administered at a dose of 4 Gy for 5 post-operative consecutive days, and pressure clips were applied for 6 months. Vancouver Scar Scale (VSS) and Patient and Observer Scar Assessments Scale (POSAS) scale were used to assess the results. This is a provisional file, not the final typeset article Results The mean age of the patients was 24.36 years (18-44 years). Postoperative follow-up ranged from 20 months. The patients underwent 5 days of postoperative radiotherapy and pressure clips for 6 months. 9 patients had no recurrence, whereas 2 patients had a mild recurrence (1 patient rejected radiotherapy). The VSS and POSAS scores significantly decreased (p < 0.01). Conclusions Five-blade core excision combined with pressure and superficial electron beam radiotherapy demonstrates effective therapeutic outcomes for ear keloid.
