The traditional management has been to perform a diagnostic needle aspiration of the tonsillar fossa. Blind needle aspiration carries with it serious complications such as inadvertent puncture of the carotid artery, jugular vein or parotid gland.

The use of intraoral ultrasonography in the diagnosis of PTA has been well established. It is non-invasive and rapidly performed at the bedside in the emergency department.

In the setting of a PTA, it provides means for guided aspiration. It is covered with either a glove or condom and placed into the oral cavity over the area in question.

Pre-application of a topical anesthetic spray is recommended to reduce gagging and overcome trismus. During the ultrasound evaluation of a PTA, the carotid artery and its relationship to the abscess cavity should be identified Figure 1.

It is generally located posterolateral to the tonsil and within mm of a PTA. Sonographically, the internal carotid artery is identified by its anechoic and tubular shape.

Its location should be evident with systematic scanning of the peritonsillar area in both sagittal and transverse planes.

A peritonsillar abscess most commonly appears as a hypoechoic or complex cystic mass. For aspiration, an 18 gauge, 2-inch needle can be inserted adjacent to the probe head and directed into the abscess cavity under ultrasound guidance Figure 2.

The ability to simultaneously image and introduce the needle allows the emergency physician to track the entire course of needle and prevent the complications such as puncturing the carotid artery.

A complex mass with mixed echogenicity is visualized. Note the vessels posterior to the mass. Courtesy of Michael Blaivas, M. Facial Abscess Ultrasound has been found to be of value in the diagnosis and treatment of odontogenic facial abscesses.

It is an effective tool in both confirming abscess formation in the superficial facial spaces and detecting the stage of infection.

Ultrasound can separate solid from fluid masses and determine the size and depth of the area of concern while revealing adjacent vital structures such arteries, veins and nerves.

This objective identification can assist in incision and drainage while helping to avoid serious complications.

It is important to note that abscesses can have a variety of sonographic appearances. Schedule Appointment via call.
