What does laryngospasm mean?
A laryngospasm is a sudden, involuntary tightening of the larynx, particularly the vocal cords, that can make breathing difficult or temporarily impossible. It is most often discussed in medical and emergency-care settings, where it may occur during intubation or anesthesia, or after exposure to irritants such as smoke, fumes, or chemical vapors. The word refers to a physical contraction rather than the ordinary sensation of a tight or anxious throat. Because a severe episode can obstruct the airway, prompt medical attention is important. The term combines “laryngo-,” referring to the larynx or voice box, with “spasm,” meaning a sudden muscular contraction. It is distinct from laryngitis, which is inflammation of the larynx, although both conditions can affect breathing and voice production.
nounA sudden, involuntary contraction of the muscles of the larynx, especially the vocal cords, which can partially or completely obstruct breathing. It may occur during medical procedures, anesthesia, or as a reaction to irritants such as smoke or strong fumes.
- A sudden, involuntary contraction of the laryngeal muscles or vocal cords that narrows or closes the airway.

Where does laryngospasm come from?
The word is formed from the combining form “laryngo-,” from Greek larinx, meaning the larynx or voice box, and “spasm,” from Greek spasmos, a contraction or convulsion. The compound reflects the medical description of a muscular contraction affecting the laryngeal structures. Its components continue to appear in related medical words such as laryngitis and laryngology.
