Laryngectomy and alaryngeal speech
After a total laryngectomy the airway and food passage are separated and the patient breathes through a permanent opening in the neck; voice is rebuilt in one of three ways — a tracheoesophageal prosthesis (TEP), esophageal speech or an electrolarynx — and all of them vibrate the pharyngoesophageal segment or an external source instead of the vocal folds.
Why it matters in the exam
Exam questions test what is expected after a total laryngectomy (no normal voice, no aspiration from the mouth, breathing through the stoma, loss of smell and sometimes taste) compared with a partial laryngectomy (a hoarse voice is present, there is aspiration risk), and what characterises each speech method. TEP is today the common rehabilitation method, because it uses air from the lungs and gives a relatively fluent, natural voice.
After a partial laryngectomy with incomplete closure, pushing exercises and the supraglottic swallow are used, because the aim is to improve closure of what remains. The drawbacks are asked too: esophageal speech is hard to learn and gives short phrases; an electrolarynx is quick to learn but sounds mechanical; and TEP needs prosthesis care, periodic replacement and attention to leakage through it.
Key points
- Total laryngectomy: permanent stoma, separated passages, no aspiration from the mouth, loss of voice.
- Partial laryngectomy: hoarse voice and aspiration risk; pushing and the supraglottic swallow.
- TEP: lung air through a valve, the common method.
- Esophageal speech: no device but hard to learn.
- Electrolarynx: quick to learn, mechanical voice.
Summary table
| Method | Air source and vibration | Advantages | Disadvantages |
|---|---|---|---|
| Tracheoesophageal prosthesis (TEP) | Lung air passes through a one-way valve into the esophagus and vibrates the pharyngoesophageal segment | Common method, fluent voice, long phrases, quick learning | Prosthesis care, replacement, possible leakage, need to occlude the stoma |
| Esophageal speech | Air taken into the esophagus from the mouth is released and vibrates the pharyngoesophageal segment | No device or surgery needed | Hard to learn, short phrases, low loudness |
| Electrolarynx | External vibration on the neck or inside the mouth | Quick to learn, available right after surgery | Mechanical voice, dependence on the device |
| Total laryngectomy — consequences | Breathing through a stoma, separation of breathing and swallowing | No aspiration from the mouth | Loss of normal voice, reduced smell and sometimes taste, need to humidify the air (HME) |
| Partial laryngectomy — consequences | Part of the larynx is preserved | Voice is present, usually hoarse | Aspiration risk; treatment with pushing and the supraglottic swallow |
