Here is a comprehensive clinical overview of nasal foreign bodies in children, drawn from Tintinalli's Emergency Medicine and The Harriet Lane Handbook.

Nasal Foreign Body in Children

Epidemiology & Common Objects

Nasal foreign bodies are almost exclusively a pediatric problem; children who insert nasal objects tend to be younger than those with ear foreign bodies.
Common objects: beads, paper, rocks, toy parts, and organic material (peas, corn, seeds, nuts, legumes).
Most children are asymptomatic at presentation.

Clinical Features

Feature	Frequency
Local pain	23–55%
Nasal discharge	7–36%
Epistaxis	Variable
Parent witnessed insertion	Variable

Key diagnostic clue: Persistent, unilateral, purulent, foul-smelling nasal discharge in a child of appropriate age — maintain a high index of suspicion for a retained foreign body.

Diagnosis

Most foreign bodies can be directly visualized.
If not visible (e.g., obscured by mucopurulent discharge/edema), consider a plain radiograph to characterize the object — especially if a button battery is suspected.

Treatment

Step 1 — Positive Pressure Techniques (First Line)

Try these before any instrumentation. Successful in >50% of cases.

Technique	Details
Self-removal (nose blowing)	Effective in children >3 years; occlude unaffected nostril and blow
Parent kiss	Up to 60% success rate. Caregiver covers child's mouth, occludes unaffected nostril with one finger, delivers a single forceful puff of air
Bag-valve mask	Used similarly to the parent kiss
High-flow oxygen	Best for objects that completely occlude the anterior nasal cavity; 10–15 L/min through suction tubing placed in the unobstructed nostril

Step 2 — Pretreatment Before Instrumentation

Topical 1% lidocaine + 0.5% phenylephrine (vasoconstrictor) to reduce mucosal edema and minimize bleeding.
Note: Phenylephrine should be avoided topically in children < 6 years old unless bleeding is refractory to other measures.
Immobilization is critical — ~20% of children require procedural sedation (most commonly ketamine).

Step 3 — Instrumentation (for non-occlusive or non-expellable objects)

Tool	Best for
Alligator forceps	Compressible, rough-surfaced, anteriorly located objects
Right-angle hook	Smooth objects that cannot be easily grasped
Foley catheter (5–8 Fr)	Small, round objects (e.g., marble); advance past object, inflate balloon, withdraw
Suction catheter	Soft or friable objects

⚠️ If the object is friable, pulling with forceps risks leaving fragments behind. ⚠️ Do not irrigate if the object is organic/expandable (rice, sponge, vegetable matter) — swelling will impede removal.

Special Considerations

🔴 Button Batteries — EMERGENT

Can cause liquefactive necrosis and septal perforation in as little as 7 hours.
Do NOT instill any nasal drops before removal — electrolyte-rich fluid causes electrolysis → severe alkaline burn.
Remove immediately; refer to ENT if not visible or initial attempt fails.

Magnets

Magnets attached to the nasal septum also require emergent removal.

Live Insects

Kill first with 2% lidocaine or mineral oil, then attempt removal.

Complications

Epistaxis
Mucosal laceration
Septal perforation (rare)
Aspiration (rare)
Retained foreign object → rhinosinusitis, mucosal/septal necrosis
Cribriform plate perforation (rare, with deep probing)

When to Refer to ENT (Otolaryngology)

Posterior objects not reachable anteriorly
Button batteries or penetrating injuries
Unsuccessful initial attempt(s)
Anatomic abnormalities
