General Guidance

  • Many cases recover following cleansing of the external ear canal using suction, dry mopping or gentle syringing.
  • If an infection is present, a topical antibiotic is preferred to systemic agents. Such treatment should be limited to 1 to 2 weeks to minimise the risk of fungal overgrowth.
