Mouth ultrasound could slash unnecessary throat punctures
NCT ID NCT07577232
First seen Jun 27, 2026 · Last updated Sep 09, 2026 · Updated 2 times
Summary
This study compares two ways to diagnose a peritonsillar abscess (a pus pocket near the tonsils): the usual physical exam versus adding a small ultrasound probe inside the mouth. About 368 adults with suspected abscess will take part. The goal is to see if ultrasound improves accuracy, reducing missed abscesses and unnecessary needle sticks.
