Also known as peritonsillar abscess drainage, this procedure treats a collection of pus that forms near the tonsil — a painful and sometimes serious complication of tonsillitis. Symptoms include severe sore throat (usually one-sided), difficulty swallowing, fever, swollen lymph nodes, and muffled voice.

Drainage is typically performed under local anesthesia, although sedation may be used for comfort. A small incision is made near the abscess to release the pus. In some cases, a needle may be used instead. Antibiotics are given, and pain improves quickly once the abscess is drained. Recovery includes hydration, rest, and soft foods. Rarely, if abscesses recur or are severe, a tonsillectomy may be recommended later. Risks include bleeding or recurrence, but this procedure is generally safe and effective.
