Foreign Body Removal: External Auditory Canal




Indications



Listen






  • • Foreign body lodged in the external auditory canal.





Contraindications



Listen




Absolute





  • • Perforated tympanic membrane.





Relative





  • • Inability to visualize the tympanic membrane.





Equipment



Listen






  • • Alligator forceps.


    • Simple forceps.


    • Ear curette (metal or plastic).


    • Right-angle hook.


    • Irrigation setup (water pik device or 20–60-mL syringe attached to cut-off butterfly tubing or angiocatheter).


    • Otoscope with operating head.


    • Lidocaine spray or viscous lidocaine suspension.


    • Frazier tip or Schuknecht suction.


    • Cyanoacrylate glue adhesive.





Risks



Listen






  • • Failed removal (20–30%).


    • Canal laceration or bleeding (10–50%).


    • Psychological stress (common; child is restrained for procedure).


    • Perforation of the tympanic membrane (1–2%).


    • Damage to the ossicles (< 1%).





Pearls and Tips



Listen






  • • If the child cannot be adequately restrained, do not attempt removal.


    • Most foreign bodies do not require urgent removal, and the child can be referred to an otolaryngologist if efforts fail.


    • Never use irrigation to remove disc batteries, vegetable matter, or expansible objects (eg, sponge).


    • Hard spherical objects can be difficult to remove. Do not use forceps because they may push the object further into the canal.


    • Sharp objects pose a higher risk of tympanic membrane perforation. Proceed with caution or refer to an otolaryngologist for removal with an operating microscope.


    • The first attempt is the best attempt. Repeated attempts with a struggling child are not likely to be successful.


    • Test for and document any dizziness or hearing loss before removal attempts. Document an additional examination after the foreign body has been removed.





Patient Preparation



Listen






  • • Reassure the child that no needles will be used.


    • Show the child the instrument that you are going to use and let him or her feel that it is not sharp.


    • Explain that holding still is extremely important in order to minimize the likelihood of pain.
