Overview
This module describes how to remove a foreign body from the external auditory canal.
Indications
Soft foreign bodies impacted at the
isthmusisthmusThe isthmus is the narrowest part of the ear canal, where cartilage gives way to bone.
— grasp/irrigate
Small foreign bodies medial to the isthmus — irrigate
Button batteries require
urgent referralurgent referralDelayed referral may result in ear canal stenosis, tympanic membrane perforation and hearing loss
to an ENT specialist
Contraindications
Uncooperative patient
Hard foreign body impacted at the isthmus
Large object close to the tympanic membrane
Lack of appropriate tools
Poor visibility of the foreign body
Patient information & consent
Always verify your patient’s identity and obtain informed consent before proceeding.
How do I explain this procedure?
“There is something stuck in your ear canal and I need to remove it, because it can cause infection and damage to the tissues in your ear.”
What can my patient expect?
“Depending on what the object is, I will try to flush it out using water; however, some objects swell up in water, so I will insert an instrument behind it and hook it. This will be uncomfortable, but not painful.”
What is my patient’s role?
“Describe exactly what the object is, as this will help me know how to remove it. Please try to remain very still during this procedure.”
Preparation
Evaluate the patient’s external auditory canal and tympanic membrane, and enquire about the patient’s ear
health
Patients may insert objects into their ear in an attempt to relieve their symptoms.

If you know that the tympanic membrane is perforated, do not instil anything into the ear.
lignocaine, alcohol, or mineral oil into the ear canal. The patient may be distressed, anxious and unable to cooperate.

Documentation
Patient notes
Equipment
The type of equipment will vary depending on the
type of foreign body
Graspable foreign bodies are foam, rubber, paper and vegetable material. Non-graspable foreign bodies are beads, pebbles and popcorn kernels.
, the patient’s cooperation and where it is located.
Alcohol-based hand rub
Otoscope, ideally with operating head
Crocodile forceps
Curette, right-angle hook or Jobson Horne probe
Equipment for ear irrigation
Wall suction, suction catheter, and scissors/blade
Superglue and a cotton-tipped applicator
Site & Positioning
Cooperative patients can either sit or lie down with the affected ear turned towards the provider.
For small children, let an assistant or parent hold the child. Wrap the child in a sheet and sit them upright, facing you on the parent’s lap with the child’s legs restrained by the parent’s crossed legs. The parent holds the child’s body with one arm, and the child’s forehead with the other. Rest the back of the child’s head against the parent’s body.
Procedure
Follow medical asepsis without gloves.
Perform hand hygiene.

the foreign body.
Retract the pinna and visualise the foreign object.
If crocodile forceps are suitable: grasp the foreign body and remove it.
If a curette or right angle hook is suitable: gently manoeuvre it behind the foreign body and rotate it, so the end is behind the object, and pull the foreign body out.
If a Jobson Horne probe is suitable: insert the probe under the foreign body, then lift the tip by depressing the outer end of the probe. Gently lever or roll out the foreign body.
Alternatively: cut a large rubber catheter at right angles to the tip. Use the catheter attached to gentle

to remove the foreign body. Pinch the catheter closed until the tip is near the foreign body.
Alternatively: place a dot of superglue on the back of a cotton-tipped applicator. Touch the applicator to the foreign object and allow the glue to harden before gently withdrawing the applicator.
Examine the patient’s ear canal and tympanic membrane once more.
Dispose of medical waste safely.
Document the completion of the procedure and your findings in patient notes.
Troubleshooting
I do not have a right angle hook/curette/Jobson Horne probe.
If the foreign body is hard and spherical, do not attempt to grasp it with the forceps, risking pushing it further into the ear canal. If you are unable to syringe it out because of the risk of swelling of the object, refer the patient to ENT.
I am unable to grasp the object, or remove it by hooking or syringing.
The foreign body may be stuck, embedded in thick wax, or touching the tympanic membrane. Refer the patient to ENT.
Attempted removal is very painful.
The foreign body may be sharp, or the tympanic membrane or ear canal may be damaged. Refer the patient to ENT.
The foreign body is styrofoam or superglue.
Use acetone to dissolve the styrofoam or loosen cyanoacrylate (superglue). Note that this should not be done when the tympanic membrane is perforated. If unsure, rather refer to ENT.
Risks
Excoriations or lacerations of the ear canal
Tympanic membrane perforation
Ossicular chain damage
