Nasal Foreign Body Removal in Children
For a child with a nasal foreign body, attempt positive-pressure expulsion first (parent's kiss technique or bag-valve-mask), followed by direct mechanical extraction with appropriate instruments if this fails, but refer immediately to ENT for button batteries or magnets which require emergent removal. 1, 2
Initial Assessment and Risk Stratification
- Identify the type of object immediately - button batteries and magnets require emergent ENT referral as they can cause septal perforation or necrosis within hours 1, 2
- Most nasal foreign bodies occur in children aged 2-4 years and are typically plastic toys or beads 1
- Look for unilateral nasal discharge, foul odor, epistaxis, or nasal obstruction as presenting symptoms 1, 3
- Do not perform blind finger sweeps - this can push the object posteriorly into the airway, creating a life-threatening aspiration risk 4, 5
Removal Technique Algorithm
First-Line: Positive-Pressure Expulsion
This should be your initial approach for most nasal foreign bodies as it avoids instrumentation and restraints while maintaining high success rates 1, 6:
- Parent's kiss technique: Have the parent occlude the unaffected nostril, place their mouth over the child's mouth, and blow a short sharp puff of air 1, 6
- Bag-valve-mask technique: Occlude the unaffected nostril and deliver positive pressure via bag-valve-mask over the child's mouth 1
- This method is underutilized despite being effective and avoiding the trauma of instrumentation 6
Second-Line: Direct Mechanical Extraction
If positive-pressure fails, proceed to instrumental removal 1, 7:
- Use appropriate visualization - adequate lighting and nasal speculum are essential 7
- Instrument selection based on object characteristics 1:
- Smooth, round objects: Use a right-angle hook or balloon-tipped catheter passed beyond the object, then pull forward
- Irregular objects: Use alligator forceps or bayonet forceps for direct grasp
- Soft objects: Consider suction catheter
- Avoid pushing the object posteriorly - this creates aspiration risk 1, 3
Third-Line: Saline Irrigation
- Nasal lavage with saline can wash out certain objects 1
- Use caution as this may also push objects posteriorly 1
Critical Contraindications and Emergencies
- Button batteries require removal within hours - they cause liquefactive necrosis and septal perforation rapidly 1, 2
- Magnets require emergent removal - risk of tissue necrosis and perforation 1
- If respiratory symptoms develop, this suggests posterior displacement into the airway and requires immediate intervention 4
- Multiple failed removal attempts increase complication risk including epistaxis and further impaction - refer to ENT after 1-2 failed attempts 2, 7
Common Pitfalls to Avoid
- Attempting removal without proper visualization leads to posterior displacement 7
- Using excessive force with instruments causes mucosal trauma and epistaxis 2
- Delaying removal of button batteries or magnets while attempting conservative measures 1, 2
- Not recognizing when to refer - if you cannot remove the object safely within 1-2 attempts, ENT consultation is warranted 7
