Acquired external auditory canal stenosis (EACS) is a major cause of conductive hearing loss in children and adults, with multiple etiologies including otological surgical procedures, blunt trauma, and chronic inflammatory diseases, which can lead to persistent hearing loss and other adverse outcomes....
Surgeons and audiologists managing acquired ear canal narrowing (stenosis) may find the prognostic data and surgical strategy comparisons useful for treatment planning, though the evidence level is likely retrospective and should be interpreted cautiously.
Acquired external auditory canal stenosis is an under-recognised cause of conductive hearing loss, and clearer surgical guidance and prognostic factors could improve referral and outcomes for both paediatric and adult patients.
- 01Acquired external auditory canal stenosis (narrowing of the ear canal) is a significant cause of conductive hearing loss (sound not reaching the inner ear).
- 02The study covers both children and adults, published in Frontiers in Pediatrics (2026).
- 03Clinical characteristics, surgical strategies, and post-operative outcomes were analysed.
- 04Prognostic factors influencing surgical success are identified.
- 05Findings aim to guide clinical decision-making for this underserved condition.
