abscess

 [ab´ses]
a localized collection of pus in a cavity formed by the disintegration of tissue. Abscesses are usually caused by specific microorganisms that invade the tissues, often by way of small wounds or breaks in the skin. An abscess is a natural defense mechanism in which the body attempts to localize an infection and wall off the microorganisms so that they cannot spread throughout the body. As the microorganisms destroy the tissue, an increased supply of blood is rushed to the area. The cells, bacteria, and dead tissue accumulate to form a clump of cream-colored liquid, which is the pus. The accumulating pus and the adjacent swollen, inflamed tissues press against the nerves, causing pain. The concentration of blood in the area causes redness. The abscess sometimes “comes to a head” by itself and breaks through the skin or other tissues, allowing the pus to drain. Local applications of heat may be used to facilitate localization and drainage.

per·i·ton·sil·lar ab·scess

extension of tonsillar infection beyond the tonsillar capsule with abscess formation between the capsule and the musculature of the tonsillar fossa.

peritonsillar abscess

Etymology: Gk, peri + L, tonsilla, tonsil, abscedere, to go away
an infection of tissue between the tonsil and pharynx, usually after acute follicular tonsillitis. The symptoms include dysphagia, pain radiating to the ear, and fever. Redness and swelling of the tonsil and adjacent soft palate are present. Treatment includes antibiotics, warm saline solution irrigation, incision and drainage with suction if there is no spontaneous rupture of the abscess, and sometimes tonsillectomy. Also called quinsy. Compare parapharyngeal abscess, retropharyngeal abscess. See also tonsillitis.

peritonsillar abscess

Quinsy ENT Advanced anaerobic infection that begins as aerobic pharyngitis or Vincent's angina Clinical Marked pharyngeal pain, dysphagia, low-grade fever, inflammation and medial displacement of the tonsil; usually unilateral, bilateral lesions may cause pharyngeal obstruction Treatment Penicillin, broad-spectrum antibiotics active against Fusobacterium necrophorum
