Nasal Foreign Body (NFB)

What is Nasal Foreign Body?

A nasal foreign body (NFB) occurs when an object becomes lodged in the nasal cavity. It is most common in children, especially those under five years of age, because they often explore the world with their mouths and noses. While many objects are harmless and can be removed easily, some may cause irritation, infection, or even airway obstruction if not addressed promptly.

In adults, NFBs are less frequent but can happen after accidental trauma, intoxication, or in patients with certain neurological or psychiatric conditions that lead to self‑insertion.

According to the Centers for Disease Control and Prevention (CDC), nasal foreign bodies account for approximately 2–5% of pediatric emergency department visits for injuries.

Common Causes

The objects that enter the nose vary by age, environment, and cultural practices. Below are the most frequently reported causes:

• Small toys or toy parts (e.g., LEGO® pieces, beads)
• Food items (e.g., peanuts, popcorn kernels, seeds)
• Plants or natural material (e.g., grass blades, tiny twigs)
• Household items (e.g., button batteries, safety pins, paper clips)
• Insect parts (e.g., dead flies, moths)
• Medication capsules or pills (especially chewable forms)
• Dental appliances (e.g., broken orthodontic brackets)
• Foreign bodies introduced deliberately in adults with mental health disorders
• Accidental insertion during nasal suction or intubation procedures
• Industrial debris (e.g., metal shavings) in occupational settings

Associated Symptoms

Symptoms depend on the size, shape, and material of the object, as well as how long it has been present.

• Unilateral nasal discharge – often clear at first and becoming purulent (yellow/green) after 24‑48 hours.
• Persistent foul odor – especially with organic material or button batteries.
• Nasal obstruction – the child may breathe through the mouth or appear to “sniff” on one side.
• Epistaxis (nosebleed) – caused by mucosal irritation or trauma during insertion.
• Fever and malaise – signs of secondary infection (e.g., sinusitis, abscess).
• Facial pain or headache – especially if the object presses against the nasal septum.
• Painful pulling or tugging sensation – common in younger children who try to remove the object themselves.
• Drooling or difficulty swallowing – may indicate that the object is high in the nasopharynx.

When to See a Doctor

Although many nasal foreign bodies can be removed in an outpatient setting, certain situations warrant urgent medical attention:

• The object is visible but cannot be removed with gentle milking or suction.
• There is significant bleeding that does not stop after a few minutes of pinching.
• The child develops fever >38°C (100.4°F) or appears ill.
• There is persistent foul odor or greenish discharge suggesting infection.
• The patient experiences painful swelling around the nose or eyes, which may signal cellulitis or an evolving abscess.
• Any suspicion of a button battery – these cause rapid chemical burns and must be removed within hours.
• Adults with neurologic impairment or psychiatric illness who cannot explain the event.

Diagnosis

Healthcare providers employ a combination of history‑taking, visual examination, and occasionally imaging to confirm the presence and type of nasal foreign body.

1. History and Physical Exam

• History: When the event occurred, what object is suspected, any prior attempts at removal, and accompanying symptoms.
• Inspection: Using a well‑lit otoscope or nasal speculum, clinicians look for the object, swelling, or discharge.
• Palpation: Gentle pressure on the surrounding tissue helps gauge depth and mobility.

2. Imaging (when needed)

• Plain radiographs (X‑ray): Useful for radiopaque objects such as metal, glass, or button batteries.
• Computed tomography (CT): Reserved for deep or complicated cases, especially when there is concern for orbital or intracranial extension.
• Ultrasound: Emerging as a bedside tool for radiolucent objects in children.

3. Endoscopic Evaluation

In specialty centers, a flexible or rigid nasendoscope may be used to visualize the nasopharynx and adjacent structures, particularly for objects located high in the nasal cavity or nasopharynx.

Treatment Options

The goal of treatment is to safely remove the foreign body, treat any resulting infection, and prevent complications.

1. Office‑Based Removal Techniques

• Positive pressure (parental blowing): Effective for smooth, round objects in children under 3 years. The caregiver blows into the child’s mouth while the nostril is sealed.
• Gentle suction: Using a pediatric nasal suction catheter.
• Instrumental removal: Small blunt forceps, alligator forceps, or curettes performed under direct vision.
• “Parent’s kiss” method: For very young infants—placing the parent’s mouth over the child’s nostril while gently occluding the opposite nostril and blowing.

2. Pharmacologic Management

• Topical nasal decongestants or saline irrigation may reduce edema and facilitate extraction.
• Antibiotics: Prescribed if secondary bacterial infection is evident (e.g., purulent discharge, fever). Common choices include amoxicillin‑clavulanate or cefdinir per CDC guidelines.
• Analgesia: Acetaminophen or ibuprofen for pain control.

3. Hospital‑Based or Surgical Removal

When office removal fails or the object is high‑risk (button battery, sharp metal, deeply embedded), the patient may need operating‑room intervention:

• General anesthesia: Provides a motion‑less field and protects the airway.
• Rigid endoscopic sinus surgery: Allows precise removal of objects lodged near the skull base or orbit.
• Incision and drainage: If an abscess or cellulitis has formed, surgical drainage may be required.

4. Post‑Removal Care

• Observe for rebleeding or persistence of discharge for 24‑48 hours.
• Continue saline nasal rinses 2–3 times daily for a week to keep the mucosa moist.
• Complete any prescribed antibiotic course to prevent sinusitis.

Prevention Tips

Most nasal foreign bodies are preventable with simple vigilance and environmental control.

• Supervise young children during play, especially with small toys or food items.
• Keep button batteries in child‑proof containers and dispose of them immediately after use.
• Regularly inspect toy parts for breakage; discard pieces smaller than a pea.
• Teach children the dangers of “nose‑picking” and encourage alternative coping strategies for nasal irritation.
• Store small household objects (paper clips, pins, beads) out of reach.
• Use protective nasal guards for children who are prone to inserting objects (e.g., in day‑care settings).
• For adults with psychiatric or neurological disorders, ensure regular risk assessments and consider protective measures.
• During family meals, cut foods into appropriate sizes and discourage children from playing with food.

Emergency Warning Signs

If any of the following occur, seek immediate medical care (emergency department or urgent care). These signs suggest a potentially dangerous situation that can rapidly progress to airway compromise, severe infection, or tissue injury.

• Difficulty breathing or noisy (stridor) breathing.
• Severe, worsening facial pain or swelling, particularly around the eyes.
• Uncontrolled nosebleed lasting more than 10 minutes.
• Fever above 39°C (102.2°F) combined with vomiting or lethargy.
• Presence of a **button battery** or any chemical‑reactive object.
• Visible object protruding from the nostril that cannot be grasped safely.
• Sudden loss of consciousness, seizures, or neurological changes.
