What are the signs and symptoms of a peritonsillar abscess (PTA)?

A peritonsillar abscess (PTA) typically presents with a combination of specific signs and symptoms that reflect the nature of this condition. The presence of an abscess indicates a localized collection of pus that can develop in the tissues surrounding the tonsils, often as a complication of tonsillitis.

Severe sore throat is a common symptom of PTA due to the inflammation and swelling in the throat area. This pain can be more pronounced on one side of the throat, depending on the location of the abscess. Trismus, or difficulty in opening the mouth, can occur due to the swelling and irritation of the surrounding muscles, making it painful and difficult to eat or swallow.

The combination of these symptoms—abscess formation, severe sore throat, and trismus—is classic for diagnosing a peritonsillar abscess. Recognizing these signs is crucial for timely intervention, as untreated PTAs can lead to serious complications, including airway obstruction.
