Overview
Foreign bodies in the throat are a common medical emergency, particularly in children, but can occur at any age. Objects can become lodged at various levels: in the pharynx (throat), larynx (voice box), or upper esophagus. The severity depends on the size and location of the object, ranging from mild discomfort to complete airway obstruction.
Choking is the fourth leading cause of unintentional injury death, with over 5,000 deaths annually in the United States alone. Children under 3 years are at highest risk due to their tendency to explore objects with their mouths and their smaller airways. In adults, food is the most common culprit, particularly in elderly individuals with swallowing difficulties or those who consume alcohol.
The anatomy of the throat creates several areas where objects commonly lodge: the tonsillar fossae, base of the tongue, vallecula, pyriform sinuses, and the cricopharyngeal area where the pharynx meets the esophagus. Understanding these locations helps in diagnosis and treatment. Quick recognition and appropriate intervention are crucial, as complete airway obstruction can cause death within minutes.
Symptoms
Symptoms of a foreign body in the throat vary depending on the size, location, and degree of obstruction. Recognition of these symptoms is critical for determining the urgency of intervention.
Complete Airway Obstruction (Emergency)
- Inability to speak, cry, or make sounds
- Universal choking sign (clutching throat)
- Inability to cough or ineffective coughing
- Cyanosis (blue coloration of lips and face)
- Loss of consciousness
- Respiratory distress with no air movement
Partial Obstruction Symptoms
- Shortness of breath with some air movement
- Cough - often forceful and persistent
- Stridor (high-pitched breathing sound)
- Wheezing or noisy breathing
- Hoarse voice or voice changes
- Drooling or inability to swallow saliva
Pharyngeal/Esophageal Foreign Body
- Difficulty in swallowing (dysphagia)
- Throat swelling sensation
- Sore throat or throat pain
- Sensation of something stuck in throat
- Pain with swallowing (odynophagia)
- Vomiting or gagging
- Excessive salivation
- Neck pain or tenderness
In Infants and Young Children
- Infant spitting up repeatedly
- Refusal to eat or drink
- Irritability or crying
- Respiratory distress
- Abnormal posturing
The presentation can be subtle, especially with smooth objects that allow some passage of air or liquids. Symptoms may develop immediately or be delayed, particularly with sharp objects that initially cause minimal symptoms but later lead to perforation or infection.
Causes
Foreign bodies in the throat can be any object that becomes lodged in the airway or upper digestive tract. The type of object varies significantly with age and circumstances.
Common Foreign Bodies in Children
- Food items: Nuts, popcorn, hot dogs, grapes, hard candy
- Toys: Small toy parts, marbles, balls
- Household items: Coins, batteries, magnets
- School supplies: Pen caps, erasers
- Natural objects: Seeds, shells, small stones
Common Foreign Bodies in Adults
- Food: Meat (especially steak), fish bones, chicken bones
- Dental items: Dentures, crowns, bridges
- Pills: Large tablets or capsules
- Intentional: In psychiatric patients or prisoners
High-Risk Objects
- Button batteries: Can cause severe tissue damage within hours
- Sharp objects: Pins, needles, toothpicks, fish bones
- Multiple magnets: Can cause intestinal perforation
- Expanding objects: Superabsorbent polymers
Contributing Factors
- Eating too quickly or not chewing properly
- Talking or laughing while eating
- Alcohol intoxication
- Neurological conditions affecting swallowing
- Dental problems affecting chewing
- Distraction during meals
Risk Factors
Certain groups and conditions increase the risk of foreign body aspiration or ingestion.
Age-Related Risk Factors
- Children 6 months to 3 years: Peak incidence due to exploration behavior
- Elderly adults: Due to decreased swallowing reflexes
- Teenagers: Risk-taking behaviors
Medical Conditions
- Neurological disorders: Stroke, Parkinson's disease, multiple sclerosis
- Esophageal disorders: Strictures, achalasia, eosinophilic esophagitis
- Mental health conditions: Psychosis, pica, developmental delays
- Dental problems: Poor dentition, ill-fitting dentures
- Sedation: From medications or procedures
Behavioral Risk Factors
- Eating while distracted or in a hurry
- Inadequate supervision of young children
- Alcohol or drug use
- Occupational exposure (carpenters, seamstresses)
- Cultural practices involving fish with bones
Diagnosis
Diagnosis of a foreign body in the throat requires rapid assessment, especially in emergency situations. The approach varies based on symptom severity and clinical presentation.
Clinical Assessment
- History: Witnessed aspiration, sudden onset symptoms
- Physical examination:
- Airway assessment (breathing, air movement)
- Vital signs and oxygen saturation
- Throat inspection if safe
- Neck palpation for subcutaneous emphysema
- Chest auscultation
Imaging Studies
- Chest X-ray: Shows radiopaque objects, air trapping
- Neck X-ray: Lateral and AP views for throat objects
- CT scan: For non-radiopaque objects or complications
- Contrast studies: Barium swallow (if no perforation risk)
Endoscopic Evaluation
- Flexible laryngoscopy: Office-based visualization
- Rigid laryngoscopy: Under anesthesia
- Esophagoscopy: For esophageal foreign bodies
- Bronchoscopy: If aspiration suspected
Special Considerations
- Not all foreign bodies are visible on X-ray
- Fish bones often require CT scanning
- Button batteries need immediate identification
- Multiple views may be necessary
Treatment Options
Treatment depends on the location, type of object, and severity of symptoms. Complete airway obstruction requires immediate intervention.
Emergency First Aid
For Conscious Adults and Children Over 1 Year
- Heimlich maneuver (abdominal thrusts):
- Stand behind the person
- Place fist above navel, below ribcage
- Grasp fist with other hand
- Quick upward thrusts
- Repeat until object expelled
- Back blows: 5 sharp blows between shoulder blades
- Alternate: 5 back blows, 5 abdominal thrusts
For Infants Under 1 Year
- 5 back blows with infant face-down on forearm
- 5 chest thrusts with infant face-up
- Check mouth for visible object
- Never perform blind finger sweep
For Unconscious Victims
- Call emergency services immediately
- Begin CPR
- Check mouth before rescue breaths
- Continue until help arrives
Medical Interventions
Non-Invasive Methods
- Observation: For small, smooth objects in esophagus
- Medications:
- Glucagon to relax esophageal sphincter
- Carbonated beverages (controversial)
- Proteolytic enzymes for meat impaction
- Foley catheter extraction: For esophageal objects
Endoscopic Removal
- Flexible endoscopy: Most common method
- Direct visualization
- Various retrieval devices
- Can assess for complications
- Rigid endoscopy: For sharp objects or failed flexible
- Timing:
- Emergent: Complete obstruction, sharp objects, batteries
- Urgent: Within 24 hours for most cases
- Elective: Chronic, asymptomatic objects
Surgical Intervention
- Reserved for failed endoscopy
- Perforation or mediastinitis
- Objects migrated beyond endoscopic reach
- Large or irregular objects
Post-Removal Care
- Observation for complications
- Soft diet initially
- Antibiotics if mucosal injury
- Follow-up for healing assessment
- Swallow evaluation if recurrent
Prevention
Most foreign body incidents are preventable through proper precautions and awareness.
