Activity Description

Peritonsillar abscess is the most common deep neck space infection in adolescents and young adults and usually arises as a complication of acute tonsillitis or pharyngitis. Clinical presentation often includes unilateral throat pain, odynophagia, dysphagia, muffled “hot potato” voice, trismus, uvular deviation, and cervical lymphadenopathy; severe cases feature drooling and respiratory distress from upper airway compromise. Diagnosis is often clinical, while point-of-care ultrasonography and contrast-enhanced computed tomography aid confirmation, delineate the extent, and exclude other deep neck infections. Management prioritizes airway assessment, hydration, analgesia, and prompt antimicrobial therapy, with needle aspiration or incision and drainage performed when indicated. Complications, although uncommon, include spread to deep neck spaces, mediastinitis, vascular injury, and septic thrombophlebitis.

Course participants learn to recognize key historical and examination findings that distinguish a peritonsillar abscess from a peritonsillar phlegmon, tonsillitis, a retropharyngeal abscess, epiglottitis, an odontogenic infection, and malignancy. Practical skills include risk stratification for airway compromise, selection of laboratory tests, and appropriate use of ultrasonography or contrast-enhanced computed tomography when diagnostic uncertainty exists. Collaboration with an interprofessional team, primary care clinicians, emergency medicine clinicians, otolaryngology clinicians, nursing staff, radiology, and pharmacy, enhances outcomes through timely airway stabilization, accurate imaging interpretation, safe procedural support, optimized antimicrobial stewardship, and reliable follow-up to confirm hydration, nutrition, and clinical resolution.


Target Audience

This activity has been designed to meet the educational needs of physicians, physician associates, nurses, pharmacists, nurse practitioners, and dentists.

Learning Objectives

At the conclusion of this activity, the learner will be better able to:

  • Differentiate peritonsillar abscess from peritonsillar phlegmon, tonsillitis, epiglottitis, and other deep neck space infections using targeted history and physical examination findings.

  • Select appropriate diagnostic testing, including rapid group A streptococcus testing and abscess aspirate culture when drainage is performed, to guide antimicrobial therapy and escalation of care.

  • Identify indications for hospitalization, intravenous hydration, corticosteroids, and close follow-up to prevent dehydration, treatment failure, and progression to deep neck space infection.

  • Collaborate with all members of the interprofessional team including specialists such as otolaryngologists, anesthesiologists, and radiologists to provide efficient, comprehensive, and coordinated care for patients with peritonsillar abscesses.
