Dysphagia with tracheostomy, after head and neck cancer, and esophageal causes
A tracheostomy, surgery or radiotherapy in the head and neck changes the structure the swallow relies on; the question is always which component changed — laryngeal airflow, the tongue, the larynx itself or the esophagus — and whether the problem is in the pharynx at all or in the esophagus.
Why it matters in the exam
The exam presents a patient with a tracheostomy tube and an inflated cuff, a patient after partial glossectomy, a patient about to start radiotherapy to the larynx or pharynx, and a patient who says food "sticks behind the breastbone". Each case tests whether you understand what changed in the mechanism and what the right recommendation is.
Recurring points: an inflated cuff does not prevent aspiration and reduces airflow through the larynx and sensation; a speaking valve requires a fully deflated cuff; the blue dye test detects some aspiration but not all of it; full tube feeding does not prevent aspiration of saliva and reflux; and before head and neck radiotherapy, swallowing exercises are started and oral eating continues.
Key points
- An inflated cuff lowers airflow, sensation and cough, and does not prevent aspiration.
- A speaking valve only with a fully deflated cuff.
- Partial glossectomy affects the oral phase; head back helps when the pharynx is intact.
- Before radiotherapy: preventive swallowing exercises and continued eating by mouth.
- Sticking behind the breastbone or regurgitation of undigested food point to the esophagus and medical work-up.
Summary table
| Condition | What changes in the swallow | What is recommended |
|---|---|---|
| Tracheostomy with an inflated cuff | Lower subglottic pressure and airflow through the larynx, reduced sensation and cough; the cuff does not seal against aspiration | Deflate the cuff before a swallow assessment when medically possible; consider a speaking valve |
| One-way speaking valve | Restores airflow through the larynx and subglottic pressure; improves voice and sensation and may reduce aspiration | Only with a fully deflated cuff, otherwise the patient cannot breathe out |
| Partial glossectomy | Long, difficult oral preparatory and transit phases; the pharyngeal phase can stay normal | Head tilted back so gravity helps move the bolus, when airway closure is normal |
| Head and neck radiotherapy | Dry mouth, stiffness (fibrosis), limited mouth opening, reduced tongue-base and laryngeal movement | Preventive swallowing exercises before and during treatment and continued eating by mouth |
| Total laryngectomy | Airway and food passage are separated, so there is no aspiration from the mouth; possible difficulty from pharyngeal narrowing | Voice rehabilitation; treat narrowing as needed |
| Esophageal problem or Zenker's diverticulum | Food sticking behind the breastbone a few seconds after the swallow, or undigested food returning hours later, bad breath and a gurgle in the neck | Medical referral for work-up; this is not pharyngeal swallowing therapy |
