Referral and warning signs
When to refer
Refer to ENT specialist/Hospital if: Unable to remove the foreign body safely. Suspected tympanic membrane perforation or other injury. Vegetable matter that cannot be removed with a hook. Uncooperative child requiring sedation/anaesthesia.
Red flags
- Severe pain.
- Significant bleeding.
- Vertigo or facial weakness (suggests middle/inner ear involvement - rare).
- Complete inability to visualize tympanic membrane after removal attempt.
- Battery suspected (urgent removal needed).
Signs and symptoms
- Sensation of blockage in the ear.
- Foreign body may be visible on inspection.
- Noise in the ear (if object is a live insect).
- Hearing loss.
- Pain (especially if attempts at removal have caused trauma or if object is sharp/large).
- Bleeding or discharge (if trauma during insertion or removal attempts).
Risk factors
- Children inserting objects (seeds, beads, stones, paper).
- Adults (insects entering canal, cotton bud tips breaking off).
- Accidental entry during activities.
Diagnosis
Clinical assessment
History of insertion or suspected entry of object. Direct visualization of the foreign body using otoscopy or good lighting.
Investigations
- Otoscopy (direct visualization).
Diagnostic criteria
Visualization of foreign body in the external auditory canal.
Management
Non-pharmacological management
- Smooth Round Foreign Bodies:
- - Syringing with clean, lukewarm water (contraindicated if tympanic membrane perforation suspected or vegetable matter like seeds). (LOC: HC3)
- - Removal with a foreign body hook (may require skill/magnification). (LOC: HC3)
- - Caution: Do NOT use forceps for round objects (risk of pushing deeper).
- - General anaesthesia may be needed in children/uncooperative adults.
- Other Foreign Bodies (with edge):
- - Removal with fine forceps (e.g., Hartmann/crocodile forceps) if edge is graspable. (LOC: HC3)
- Insects:
- - Instill clean cooking oil or water to kill the insect first.
- - Syringe out with warm water.
- - Cockroaches may need forceps removal due to leg hooks. (LOC: HC3)
- Impacted Seeds/Vegetable Matter:
- - DO NOT SYRINGE WITH WATER (risk of swelling).
- - Attempt removal with hook.
- - If unsuccessful, refer immediately.
- General:
- - Suction may be useful if available (specialist).
- - Assess for trauma to the ear canal or tympanic membrane after removal.
Pharmacological treatment
- Topical antibiotic drops (e.g., Ciprofloxacin, Neomycin/Polymyxin/Hydrocortisone) may be needed AFTER removal if trauma or secondary infection is present.
Monitoring
Check canal and tympanic membrane integrity after removal.
Complications
- Trauma to ear canal skin.
- Tympanic membrane perforation.
- Otitis externa (secondary infection).
- Pushing object deeper, potentially damaging middle ear structures.
- Bleeding.
Prevention
- Educating children not to insert objects into ears.
- Avoiding use of cotton buds inside the ear canal.
- Using ear protection in environments with flying insects/debris.
Patient education
- Explanation of the problem and removal method.
- Advice against putting objects in the ear.
- How to manage insects in the ear (instill oil/water).
- Need for referral if removal unsuccessful/complicated.
Uganda-specific notes
Common problem, especially seeds and insects. Syringing and simple forceps/hook removal feasible at HC3. Referral needed for difficult cases or complications. Discourage harmful removal attempts.
