Abstract
Peritonsillar abscess (PTA) is a complication of tonsillitis and other upper respiratory infections; it is the most common deep space infection that presents to the emergency department. Diagnosis is often challenging, and even among experienced otolaryngologists, clinical exam has been shown to be only 78% sensitive and 50% specific in diagnosis of this pathology. Sonography is used both diagnostically and to provide procedural guidance in real time.
