Bilateral peritonsillar abscess: a case study and literature review.

While peritonsillar abscesses are the most common deep neck infections, bilateral forms are rare. A peritonsillar abscess occurs when pus accumulates in the peritonsillar space, located between the tonsils and superior constrictor muscle, causing medial displacement of the uvula, trismus, odynophagia or even upper airway obstruction. High clinical suspicion is needed to diagnose bilateral peritonsillar abscess due to frequent history, computerized tomography scan of the neck with IV contrast facilitates accurate diagnose and a full assessment of the patient. Incision and drainage are needed to evacuate the pus along with systemic antibiotics to relieve patient symptoms followed by interval tonsillectomy, which usually done after 6 weeks.
