Peritonsillar Abscess (Quinsy)
Peritonsillar abscesses usually occur in patients with recurrent tonsillitis or those with chronic tonsillitis that has been inadequately treated. the absence of any history of tonsillitis is not uncommon.
This disease process is more common in young adults. Usually the process begins with a peritonsillar cellulitis that progresses into an abscess that extends beyond the tonsillar capsule. The abscess forms in the potential space between the buccopharyngeal fascia and the capsule itself. Abscess within the body of the tonsil itself is actually rare.
The swelling usually causes edema of the soft palate and displaces the tonsil medially forward and downward. This generally causes deviation of the uvula to the normal side.
