The facts most likely to be tested
The classic presentation of a nasal foreign body is unilateral, foul-smelling purulent rhinorrhea in a young child.
Button batteries and magnets are considered emergent foreign bodies that require immediate removal to prevent septal perforation or necrosis.
The mother's kiss technique is a safe, non-invasive first-line maneuver for removing non-impacted nasal foreign bodies.
Positive pressure techniques are contraindicated if the foreign body is a button battery due to the risk of mucosal injury.
Instrumentation with alligator forceps or a right-angle hook is the standard approach for removal of non-emergent, visualized objects.
Topical vasoconstrictors like oxymetazoline are used prior to removal to reduce mucosal edema and improve visualization.
General anesthesia or sedation is required for removal if the object is impacted, posteriorly located, or if the patient is uncooperative.
Vignette unlocked
A 3-year-old boy is brought to the urgent care clinic by his mother due to a 4-day history of foul-smelling, green-tinged discharge from his right nostril. The mother denies any fever, cough, or recent upper respiratory infection. On physical examination, the child is cooperative, and a purulent, unilateral nasal discharge is noted. Upon anterior rhinoscopy, a metallic, circular object is visualized lodged in the inferior meatus of the right nasal cavity.
What is the most appropriate next step in management?
Immediate removal of the foreign body
The presence of a metallic, circular object (likely a button battery) constitutes a medical emergency due to the risk of rapid tissue necrosis and septal perforation, necessitating immediate removal.

Etiology / Epidemiology
Common in toddlers/preschoolers due to curiosity. Most objects are organic (seeds/food) or inorganic (beads/toys).
Clinical Manifestations
Classic presentation is unilateral, foul-smelling purulent rhinorrhea. Unilateral nasal obstruction is the hallmark.
Diagnosis
Diagnosis is clinical via direct visualization. Flexible fiberoptic rhinoscopy is the gold standard if visualization is difficult.
Treatment
Removal via positive pressure technique (parent's kiss) or alligator forceps. Button batteries require immediate removal.
Prognosis
Excellent with removal. Aspiration is the primary risk if the object is dislodged posteriorly.

Epidemiology & Etiology
Predominantly affects children aged 1-4 years. Objects are typically placed by the patient or peers. Button batteries and magnets represent high-risk categories requiring urgent intervention.
Pertinent Anatomy
The nasal cavity is narrow, with the inferior meatus being the most common site for impaction. The floor of the nose is relatively flat, facilitating the posterior movement of objects toward the nasopharynx.
Pathophysiology
Initial obstruction leads to local mucosal irritation and inflammation. Prolonged retention causes secondary bacterial infection and localized tissue necrosis. Organic objects (e.g., beans) may expand due to moisture absorption, complicating removal.
Clinical Manifestations
Presentation is typically unilateral nasal discharge, often described as foul-smelling or purulent. Patients may present with epistaxis, sneezing, or localized pain. Red flags include fever, facial swelling, or signs of systemic infection indicating secondary sinusitis.
Diagnosis
Diagnosis is primarily clinical through direct visualization using a nasal speculum and light source. Flexible fiberoptic rhinoscopy is the gold standard for deep or non-visualized objects. Radiographs are only indicated if a radiopaque object (e.g., metal, battery) is suspected.
Treatment
First-line management is the positive pressure technique (e.g., 'mother's kiss'). Mechanical removal is performed using alligator forceps or a right-angle hook. Button batteries and magnets are emergencies requiring immediate ENT referral to prevent septal perforation or tissue necrosis.
Prognosis
Prognosis is excellent following successful removal. Aspiration into the airway is the most significant complication during the removal process. Patients should be monitored for signs of nasal septal hematoma or persistent infection.
Differential Diagnosis
Sinusitis: usually bilateral and associated with systemic symptoms
Nasal polyp: chronic, pale, boggy mass rather than acute obstruction
Choanal atresia: congenital, present at birth, not acute onset
Nasal tumor: chronic, progressive, often associated with bloody discharge
Adenoid hypertrophy: chronic mouth breathing and snoring
