MANAGEMENT

Removal
Young and uncooperative patients must be immobilized for successful removal.
All of these methods may push object deeper into canal.

  • Irrigation

    • warm water flushed into canal with 20 ml syringe attached to a flexible IV catheter tip contraindicated with TM perforation, food matter, or disc batteries

  • Instrumentation - best for objects in the lateral 1/3 of the canal

    • Alligator forceps or Hartman forceps - look for an edge to grab foreign body and withdraw

    • Ear Curette - visualize FB with otoscope, pass curette beyond FB and withdraw

  • Katz Extractor

    • insert catheter past FB, push on syringe to inflate small balloon and extract

  • Suction-usually not successful

Insect removal requires insect to be killed before removal with insertion of mineral oil drops into canal

Treatment

  • Patients who undergo uncomplicated removal do not need any follow up care

  • Antibiotic drops

    • Patients who sustained any abrasion or irritation of canal during removal procedure should receive antibiotic drops

    • Floxin Otic - 2 drops affected ear BID for 7 days

  • Surgery / Other Procedures

    • OR with sedation for difficult removals or uncooperative patient

ENT Referral

  • Outpatient

    • failure to remove

    • significant injury to canal

    • perforated TM

    • object is wedged in canal or against the TM

  • Immediate consult

    • Disc battery

    • Glass or sharp object

    • Liquefaction necrosis

Written instructions should include:
