peritonsillar abscess
Collection of pus between the tonsillar capsule and surrounding pharyngeal muscles, often complicating streptococcal pharyngitis.
Full Definition
Peritonsillar abscess is a deep-space neck infection characterized by a collection of pus in the potential space between the tonsillar capsule and the superior constrictor muscle of the pharynx. This condition typically occurs as a complication of acute tonsillitis or pharyngitis, most commonly due to group A Streptococcus, though polymicrobial infections are frequent. Patients present with severe sore throat, difficulty swallowing, trismus, and a muffled 'hot potato' voice. The condition requires urgent drainage and antibiotic therapy to prevent serious complications including airway obstruction.
Usage
Usage note: Write as one word 'peritonsillar', not hyphenated. 'Quinsy' is archaic but may appear in historical references.
