Peritonsillar Abscess
Excerpt
Peritonsillar abscess, also known as quinsy, is the localized collection of pus in peritonsillar space between the tonsillar capsule and superior constrictor muscle. It was first described in the 14th century and became more extensively known in the 20th century after the antibiotic era started.
Clinical Anatomy
Peritonsillar space consists of loose connective tissue between the fibrous capsule of palatine tonsils medially and superior constrictor muscle laterally. The anterior and posterior tonsillar pillar contribute to anterior and posterior limits, respectively. Superiorly, this space is related to torus tubarius, while pyriform sinus forms the inferior limit. Since this space is composed of loose connective tissue, it is highly susceptible to abscess formation following infection.
