IL-33, IL-25, IL-6, SOD, and MDA levels were measured by ELISA. Eustachian tube function was evaluated using the Endoscopic Evaluation of the Eustachian Tube (3ET) scoring system.Results: Comparative analysis revealed distinct molecular profiles between POME and CCOME, with POME showing significantly reduced IL-33 levels (p=0.046) but elevated SOD activity (p=0.015), along with a non-significant trend toward higher MDA (p=0.083). Temporal analysis demonstrated peak expression of both IL-25 and IL-33 at 6 months post-radiation. Correlation studies identified significant associations between IL-33 (r=0.391) and IL-6, as well as between IL-25 (r=0.483) and IL-6 (both p< 0.01). Clinically, IL-25 levels showed positive correlation with 3ET endoscopic scores (r=0.407, p=0.021) and were significantly reduced following tympanostomy tube placement (p=0.024). Notably, no direct correlation was observed between IL-33 and IL-25 (p> 0.05), nor were any significant associations found with allergic comorbidities (all p> 0.05).Conclusion: IL-33 and IL-25 synergistically drive ILC2-mediated chronic inflammation in radiation-induced OME, with IL-25 emerging as a biomarker for radiotherapy-associated Eustachian tube dysfunction. The 6-month cytokine surge post-radiation highlights a therapeutic window for targeted interventions to mitigate long-term complications.
