Emergency And Acute Medicine – Nasal Foreign Body
Basics Description
A nasal foreign body is an object lodged within the nasal cavity and represents the most common site of foreign body insertion in children. The type of object is limited primarily by the size of the nostril. Children between 2–6 years are most commonly affected, with increased risk in those with intellectual disability or psychiatric illness. Impaction and removal difficulty worsen over time due to mucosal swelling or expansion of organic material when moistened. Sinusitis is the most frequent complication, though foreign bodies may migrate into the sinuses. Serious complications include septal perforation, bronchial aspiration, and, with button batteries, ischemic mucosal injury, turbinate or septal damage, and saddle-nose deformity.
Etiology
Common objects include food items such as beans and seeds, beads, rocks, paper, toy parts, sponge fragments, vegetable matter, insects, and live worms. Button batteries pose a particularly high risk and require rapid removal due to tissue necrosis and structural damage. Magnets, often used to mimic nasal piercings, may become embedded in tissue and are difficult to remove; ingestion carries a risk of intestinal perforation. Glass fragments are less common but possible.
Diagnosis Signs And Symptoms
Many nasal foreign bodies are asymptomatic. When present, symptoms include unilateral nasal obstruction, nasal pain, difficulty breathing through the nose, and unilateral nasal discharge that may be foul-smelling or chronic. Other findings include halitosis, sinus discomfort, persistent epistaxis, local inflammation, and septal perforation. Delayed presentations are common when insertion is unwitnessed and may be misdiagnosed as sinusitis.
Essential Workup
Direct visualization of the foreign body within the nostril is essential. Both nostrils must always be examined.
Diagnosis Tests And Interpretation
Fiberoptic visualization may be required if the object is not seen on routine examination. Sinus imaging may be considered for prolonged retention or persistent symptoms despite removal and antibiotics. Chest or abdominal imaging may be needed if aspiration or ingestion is suspected.
Differential Diagnosis
Conditions to consider include sinusitis, swollen inferior turbinate, rhinitis, nasal polyps, benign tumors such as hemangioma, malignant tumors including lymphoma or rhabdomyosarcoma, congenital nasal masses, retropharyngeal abscess, traumatic nasal injury, structural nasal deformities, and rhinitis medicamentosa.
Treatment
Prehospital care emphasizes transport in the sitting position and avoidance of distressing interventions that may provoke aspiration. In the emergency department, topical vasoconstrictors may be used to reduce mucosal edema or bleeding. Positive-pressure techniques are particularly effective in children and involve occluding the unaffected nostril while applying a brisk puff of air to the mouth, often performed by a caregiver.
Mechanical removal options include hooked probes or alligator forceps for anterior, graspable objects; suction catheters for smooth, round objects; cyanoacrylate tissue glue applied to a swab handle; balloon catheters such as Foley or Fogarty passed beyond the object and withdrawn after inflation; magnets for metallic objects; and snare techniques using fine wire. Procedural sedation may be required if the child is uncooperative or removal attempts fail.
Medication
Topical agents may include cocaine 4%, lidocaine 4%, oxymetazoline 0.05%, or phenylephrine 0.125–0.5%. Procedural sedation is used selectively.
Follow Up Disposition
Admission or referral for operative removal is required if the foreign body cannot be removed in the emergency department or if general anesthesia is necessary. Discharge is appropriate once removal is successful and airway compromise is excluded. Patients with button battery exposure require monitoring for delayed complications.
Follow Up Recommendations
Parents should seek immediate care if the child develops coughing, wheezing, noisy or difficult breathing, vomiting, choking, drooling, neck or throat pain, or inability to swallow. Medical review is also advised for fever, headache or facial pain, persistent epistaxis, or ongoing nasal discharge.
Key Practice Insights And Common Pitfalls
Always consider a nasal foreign body in children aged 2–6 years presenting with unilateral, foul-smelling nasal discharge. Caregiver-assisted positive-pressure techniques are often effective and minimally traumatic. Combining topical lidocaine with oxymetazoline can improve comfort and visualization during removal.
