만성 외이도염의 치료: 전통적 접근법에서 새로운 치료법까지

초록

Chronic otitis externa is a long-standing inflammatory disease of the external auditory canal, potentially resulting from a combination of immunological, structural, and environmental factors. Effective management requires a comprehensive approach, including the identification and elimination of triggering factors, local anti-inflammatory and antimicrobial therapy, and evaluation of associated systemic conditions. Standard treatment modalities—topical corticosteroids and antiseptic or antibiotic drops—remain the cornerstone of care. In refractory or anatomically restricted cases, systemic medications or surgical interventions may be considered. Recent advances have introduced adjunctive options, includ- ing topical biologics (e.g., janus kinase [JAK] inhibitors), sustained-release drug delivery systems, non-antibiotic anti- microbial strategies such as bacteriophage therapy and antimicrobial blue light, and cell sheet transplantation. While still under investigation, these approaches offer new possibilities for addressing the limitations of current treatments, such as drug-related adverse effects, rising antibiotic resistance, and challenges associated with treatment adherence in long-term care. This review provides an up-to-date overview of current therapies and introduces new developments that may broaden future treatment options.
