Physical Examination Guide
Systematic approach to examining a child with dysphagia or swallowing difficulties
Diagnostic Approach
Initial Assessment
For a child presenting with dysphagia, the initial assessment should include:
- Detailed feeding and swallowing history with attention to developmental milestones
- Thorough physical examination focusing on oropharyngeal structures and neurological status
- Nutritional assessment and growth parameters
- Assessment of respiratory status and history of respiratory complications
Diagnostic Classification of Pediatric Dysphagia
Dysphagia in children can be classified by phase and etiology:
| Phase | Definition | Key Features |
|---|---|---|
| Oral Preparatory Phase | Food processing in mouth prior to initiation of swallow | Difficulties with lip closure, chewing, bolus formation |
| Oral Phase | Transport of bolus from anterior to posterior oral cavity | Problems with tongue mobility, coordination, or strength |
| Pharyngeal Phase | Swallow reflex triggering through pharynx | Delayed swallow trigger, residue in pharynx, aspiration risks |
| Esophageal Phase | Transport through esophagus to stomach | Dysmotility, strictures, reflux, anatomical abnormalities |
Differential Diagnosis
| System | Conditions | Red Flags |
|---|---|---|
| Neurological |
- Cerebral palsy - Traumatic brain injury - Neuromuscular disorders - Cranial nerve abnormalities - Chiari malformation |
- Asymmetric oral movements - Global developmental delay - Progressive weakness - Altered mental status - Abnormal gag reflex |
| Anatomical |
- Cleft palate - Laryngeal cleft - Tracheoesophageal fistula - Vascular ring - Esophageal stricture |
- Choking with first feeds - Cyanosis during feeding - Food impaction - Noisy breathing during swallows - Regurgitation of undigested food |
| Inflammatory |
- Eosinophilic esophagitis - Crohn's disease - Reflux esophagitis - Caustic ingestion - Infectious esophagitis |
- Food avoidance behaviors - Heartburn or chest pain - Progressive dysphagia - Family history of atopy - Unexplained weight loss |

Laboratory and Diagnostic Studies
Consider these studies based on clinical presentation:
| Investigation | Clinical Utility | When to Consider |
|---|---|---|
| Videofluoroscopic Swallow Study (VFSS) | Gold standard for evaluating all phases of swallowing; detects aspiration | Suspected aspiration, pharyngeal phase disorders, unclear etiology |
| Fiberoptic Endoscopic Evaluation of Swallowing (FEES) | Direct visualization of hypopharynx during swallowing | Unable to transport to fluoroscopy, need for detailed examination of pharyngeal structures |
| Upper GI Series | Evaluates esophageal anatomy and function | Suspected structural abnormalities, esophageal phase dysfunction |
| Esophagogastroduodenoscopy (EGD) | Direct visualization of mucosa, allows for biopsies | Suspected eosinophilic esophagitis, stricture, mucosal disease |
| High-Resolution Esophageal Manometry | Evaluates esophageal motility and LES function | Suspected achalasia, esophageal dysmotility, cricopharyngeal dysfunction |
Advanced Studies
Reserve for specific clinical scenarios:
| Investigation | Clinical Utility | When to Consider |
|---|---|---|
| Brain MRI | Evaluate CNS structures affecting swallowing function | Neurological signs, suspected posterior fossa abnormalities, cranial nerve dysfunction |
| Bronchoscopy | Evaluate airway for compression, clefts, or laryngeal abnormalities | Recurrent aspiration, suspected laryngeal cleft, stridor with feeding |
| pH Impedance Monitoring | Evaluates acid and non-acid reflux | Suspected GERD-related dysphagia, recurrent aspiration pneumonia |
| Scintigraphy (Milk Scan) | Quantifies aspiration and gastric emptying | Suspected microaspiration, gastric emptying disorders |
| Genetic Testing | Identify underlying genetic disorders | Dysmorphic features, suspected syndromic conditions, multiple congenital anomalies |
Diagnostic Algorithm
A stepwise approach to diagnosing dysphagia in children:
- Determine phase of dysphagia based on clinical history and bedside evaluation
- Assess for "red flags" requiring urgent evaluation
- Perform growth assessment and nutritional status evaluation
- Consider VFSS or FEES for suspected aspiration or pharyngeal phase dysfunction
- Investigate esophageal causes with Upper GI and/or EGD if indicated
- Assess for neurodevelopmental causes with appropriate neuroimaging if indicated
- Evaluate for behavioral/sensory component with multidisciplinary assessment
- Consider specialized testing based on initial findings (e.g., manometry, pH monitoring)
Management Strategies
General Approach to Management
Key principles in managing pediatric dysphagia:
- Multidisciplinary team approach: Coordinate care between specialists
- Address underlying causes: Treat specific etiologies when identified
- Ensure nutritional adequacy: Maintain growth and development
- Prevent aspiration: Implement strategies to minimize aspiration risk
- Regular reassessment: Monitor progress and adjust interventions as needed

| Steroid Therapy |
- Topical swallowed corticosteroids - Systemic steroids for acute inflammation - Elimination diet trials |
- High evidence for eosinophilic esophagitis - Consider endoscopy with biopsies pre/post treatment - Monitor for side effects - Often combined with dietary therapy |
| Botulinum Toxin Injections |
- Targeted injections to cricopharyngeus - Used for hypertonicity or spasticity - Temporary effect requiring repeat injections |
- Moderate evidence for cricopharyngeal achalasia - Low evidence for generalized dysphagia - Consider as trial before surgical intervention - Performed under anesthesia or sedation |
| Antibiotics/Antifungals |
- Targeted therapy for infectious causes - Empiric therapy in immunocompromised patients |
- High evidence for infectious esophagitis - Consider in immunocompromised patients - Limited role in general dysphagia management - Culture-directed when possible |
