Transoral pharyngeal ultrasonography (TOPU) is a new ultrasound technique for otorhinolaryngology. TOPU is applicated from transoral carotid ultrasonography, and useful for delineation of pharyngeal lesions. Peritonsillar abscesses is well known as common disease in otorhinolaryngology, and often needed a puncture drainage of abscesses. This procedure usually is performed blindly into the inside of pharynx, thus, it has a risk of fatal complications and low success rate. TOPU-guided needle aspiration appears to be useful for safe drainage of peritonsillar abscesses. We report a case of peritonsillar abscess whom we performed puncture drainage with TOPU guiding.
