User:Mr. Ibrahem/Peritonsillar abscess

Peritonsillar abscess (PTA), also known as quinsy, is an accumulation of pus due to an infection behind the tonsil. Symptoms may include fever, throat pain, trouble opening the mouth, and a change to the voice. Severe cases may result in drooling. Pain is usually worse on one side. Complications may include blockage of the airway or aspiration pneumonitis.

They are typically due to infection by a number of types of bacteria. Often it follows streptococcal pharyngitis; thought, they may occur spontaneously. They do not typically occur in those who have had a tonsillectomy. Diagnosis is usually based on the symptoms. Medical imaging, such as ultrasound or CT scan, may be done to rule out complications.

Treatment is by antibiotics, removing the pus, sufficient fluids, and NSAIDs. Antibiotics commonly used include amoxicillin/clavulanate. Steroids may also be useful. It may be reasonable to attempt initially treatment with medications alone. Admission to hospital is generally not needed. In the United States about 3 per 10,000 people per year are affected. Young people between the age of 15 and 19 are most commonly affected.
