Step 1 of 6
Entry, Triage & Airway / Aspiration Safety
Define the symptom · screen for airway emergency · stratify aspiration risk · activate urgent pathway when red flags present.
The first decision in every patient with dysphagia is whether
the airway is at risk. Stridor, respiratory distress,
cyanosis, inability to handle secretions, severe aspiration,
complete obstruction, rapidly progressive symptoms and toxic
appearance are airway-emergency indicators that mandate
upright positioning, oxygen, suction, NPO status, IV access,
and airway stabilisation — with flexible intubation, rigid
bronchoscopy or emergency tracheostomy as appropriate. See
framework_red_flag and the bespoke aspiration_severity_matrix.
Define the symptom precisely. True dysphagia (difficulty moving bolus from mouth to stomach), odynophagia (painful swallowing), globus (constant lump sensation unrelated to meals), feeding difficulty, aspiration (cough, wet voice, recurrent pneumonia), choking episodes, regurgitation, and weight loss map to different differentials. Bedside classification into oropharyngeal vs oesophageal dysphagia drives the next step.
Urgent adult differentials at triage include supraglottic carcinoma, retropharyngeal abscess, oesophageal foreign body and severe laryngeal oedema. In children, consider choanal atresia, vallecular cyst, laryngomalacia, haemangioma, lymphangioma, recurrent respiratory papillomatosis, bilateral vocal-fold paralysis, and laryngotracheal cleft.
- Stridor / respiratory distress / cyanosis → airway emergency pathway
- Inability to handle secretions / drooling → urgent airway protection
- Suspected foreign body → rigid endoscopy under controlled conditions
- Toxic appearance / sepsis → resuscitate + image + cover empirically
- Define symptom: true dysphagia · odynophagia · globus · feeding difficulty · aspiration · choking · regurgitation
- Acute presentation with red flags → urgent ENT / GI / MDT pathway
- Progressive dysphagia + weight loss → malignancy concern
- Recurrent pneumonia → silent aspiration screen
Key statistics
Stroke-related dysphagia prevalence
≈50% acute stroke
Roughly half of patients in the acute phase of stroke develop dysphagia detectable on bedside or instrumental screen; aspiration pneumonia is a leading early complication.
Silent aspiration in stroke
Up to 40% of aspirators
A substantial proportion of stroke patients who aspirate do so silently (no overt cough), which is why bedside screens with cough alone miss the diagnosis.
★ High-yield pearls (chapter-wide)
- Airway and aspiration risk come first — secure ventilation and protect the lungs before pursuing the cause.
- True dysphagia, odynophagia, globus, and feeding difficulty are different complaints — define the symptom precisely at the outset.
- Solids-only suggests mechanical obstruction; solids progressing to liquids suggests stricture or malignancy; liquids ≥ solids from onset suggests motility disease.
- Silent aspiration is the rule in stroke, Parkinson disease, dementia and post-radiation patients — absence of cough does NOT exclude aspiration.
- Progressive dysphagia with weight loss is malignancy until proven otherwise — proceed to flexible endoscopy + cross-sectional imaging + biopsy.
- Referred otalgia with dysphagia is a head-and-neck cancer red flag — examine the pharynx and larynx endoscopically.
- Flexible fibreoptic laryngoscopy is mandatory in adult dysphagia with weight loss, odynophagia, referred otalgia, smoking history or hoarseness.
- FEES and MBS (VFSS) are complementary, not interchangeable — pick the modality that answers the clinical question and the patient's logistic constraints.
- Cricopharyngeal dysfunction, Zenker diverticulum and motility disorders can mimic each other — manometry plus dynamic imaging is needed to separate them.
- Feeding-tube decisions are clinical, ethical and patient-centred — frame NG / PEG / gastrostomy choices around prognosis, quality of life and shared decision-making.

Decision tree
The airway / aspiration screen is the first gate. For a stable patient the bedside oropharyngeal-vs-oesophageal split routes through ten aetiology-keyed pathways (A–J). Two cross-cut cards capture the paediatric population (any age <18 → J) and the silent-aspiration high-risk groups that bypass character-based routing.
