Peritonsillar abscess

Authoring team

Quinsy is a complication of acute tonsillitis, usually due to streptococcal infection.

It is a collection of pus arising outside the capsule of the tonsil in close relationship to its upper pole.

It causes more severe symptoms, including trismus (lockjaw), a muffled voice, a displaced uvula, and an enlarged, displaced tonsil, with swelling of the peri-tonsillar region.
