Understanding and Comparing Current Practice for Ear Keloid Scars: A Narrative Systematic Review

A keloid scar is a benign fibroproliferative disorder that is characterized by excessive tissue growth beyond the original wound. The psychosocial and surgical challenges that arise can present potentially devastating long-term consequences for patients, particularly in demographics with a high incidence of keloid scar formation. Considering the high incidence of keloids with an estimated 11 million cases annually, particularly in those of Asian and African backgrounds, an understanding of their exact pathophysiology remains challenging. Piercing-induced keloids of the ear are a common cause of ear keloids, yet the exact mechanism and optimal treatments are of considerable debate. This narrative review aims to evaluate current treatment modalities for ear keloids, focusing on their association with ear piercings and the implications for management.
