A Novel Technique for Intraoral Ultrasound-Guided Aspiration of Peritonsillar Abscess

Development of a Novel Ultrasound-guided Peritonsillar Abscess Model for Simulation Training

Introduction Peritonsillar abscess (PTA) is the most common deep space infection of the head and neck presenting to emergency departments.1 No commercial PTA task trainer exists for simulation training. Thus, resident physicians often perform their first PTA needle aspiration in the clinical setting, knowing that carotid artery puncture and hemorrhage are serious and devastating complications. ...

A randomised trial comparing intraoral ultrasound to landmark-based needle aspiration in patients with suspected peritonsillar abscess.

OBJECTIVES Traditionally, emergency physicians (EPs) have used anatomic landmark-based needle aspiration to drain peritonsillar abscesses (PTAs). If this failed, an imaging study and/or consultation with another service to perform the drainage is obtained. Recently, some EPs have used ultrasound (US) to guide PTA drainage. This study seeks to determine which initial approach leads to greater su...

Intraoral ultrasound in the diagnosis and treatment of suspected peritonsillar abscess in the emergency department.

UNLABELLED Peritonsillar abscess (PTA) can be a life-threatening disease and may lead to significant complications without drainage. OBJECTIVES To describe the utility of ultrasound (US) in the evaluation of potential PTA and US-guided PTA drainage. METHODS The authors performed a retrospective US quality assurance review of all patients over 18 years of age scanned by emergency physicians ...

I-46: Ultrasound Guided Aspiration of Ovarian Cyst

Ultrasonography is the primary imaging tool for a patient considered to have an ovarian cyst. On a sonogram, simple ovarian cysts have a uniformly thin, rounded wall and a unilocular appearance that is either hypoechoic or anechoic. They usually measure 2.5-15 cm in diameter, and posterior acoustic enhancement (a hyperechoic area) may be visible deep to the fluid-filled cyst. Most commonly, the...
