Abstract:
Peritonsillar abscess (PTA) is a common complication to acute tonsillitis. The treatment is drainage of the abscess, but many needle aspirations are unsuccessful due to a low diagnostic accuracy based on oral examination only. In this article, we describe how intraoral ultrasound can be added to improve the diagnostic work-up of PTA and present a novel technique for ultrasound-guided aspiration of PTA, using a small pencil-shaped transducer. We present our first clinical experiences with this technique and describe how it could be integrated in a clinical setting to guide safe and successful needle aspirations of PTA.

Ultrasound I: Abdominal Ultrasonography
Abdominal ultrasonography, commonly known as abdominal ultrasound, is a vital, non-invasive medical imaging technique widely used in healthcare.
Procedure:
This diagnostic tool allows the clinician to visually inspect internal structures within the abdomen, including vital organs such as the liver, gallbladder, pancreas, kidneys, and spleen.
The abdominal ultrasound process begins with applying a special gel to the patient's skin over the abdomen. This gel enhances the...
