Think ultrasound first for peritonsillar swelling

SONOSIM SUMMARY: This article from the American Journal of Emergency Medicine encourages the use of ultrasound for ruling out peritonsillar abscess and for needle-guided peritonsillar abscess drainage. The authors affirm that peritonsillar abscesses are difficult to differentiate from peritonsillar cellulitis, and that blind needle-drainage is risky due to the close proximity of the internal carotid artery; therefore, ultrasound may aid in both the diagnosis and drainage of peritonsillar abscesses.

Secko M, Sivitz A. Think of ultrasound first for peritonsillar swelling. American Journal of Emergency Medicine. 2015 Apr; 33(4): 569 – 72

Abstract

Peritonsillar abscess (PTA) is one of the most common deep neck space infections that can potentially have life-threatening complications if inadequately diagnosed and not treated promptly. The ability of clinicians to reliably differentiate PTA from peritonsillar cellulitis by physical examination alone is limited and blind needle aspiration, the typical method of diagnosis of PTA, is also unreliable. We review the available evidence supporting the use of ultrasound, either intraoral ultrasound or transcutaneous ultrasound to be the initial imaging modality of choice for evaluation of PTA and be used for real-time needle guidance.
