According to a systemic review published in Academic Emergency Medicine entitled, “Test characteristics of ultrasound for the diagnosis of peritonsillar abscess: A systematic review and meta-analysis”, Dr Kim MD, the primary author of the research, they concluded that Ultrasound demonstrates high sensitivity and moderate specificity for ruling out Peritonsillar abscess (PTA) and diagnosis.
One of the most common head and neck infections is PTA. It has an estimated incidence between 10 and 40 cases per 100,000 annually and about 63,000 emergency department (ED) visits in the US annually.
PTA refers to the purulent collection between the palatine tonsil and its capsule, developing from initial tonsillitis or pharyngitis.
The complications of PTA include airway obstruction, aspiration pneumonitis, mediastinal extension, and carotid sheath erosion.
Distinguishing peritonsillar abscess (PTA) from peritonsillar cellulitis using clinical assessment is challenging. Many features overlap for both conditions and physical examination is only about 75% sensitive and 50% specific for diagnosing PTA. The primary objective of this systematic review was to determine the test characteristics of Ultrasound for diagnosing PTA when compared to a reference standard of computed Tomography or acquisition of pus via needle aspiration or incision and drainage. The systematic review followed PRISMA-DTA guidelines.
