Peritonsillar abscess

Last edited: 4/13/2026

Overview

Peritonsillar abscess (PTA) is a deep neck infection characterized by pus accumulation in the peritonsillar space, often complicating acute tonsillitis and potentially leading to severe complications such as airway obstruction if untreated 1 2 22.

Diagnosis

Clinical Presentation: Fever, sore throat, dysphagia, trismus, and muffled voice (hot potato voice) 1 2 6 66.

Diagnostic Imaging: Ultrasound is often first-line, with computed tomography (CT) reserved for complex cases or vascular assessment 3 5 30 35.

Ultrasound Findings: Presence of fluid collection in the peritonsillar space, hypoechogenic with posterior enhancement 3 5 35.

CT Findings: Useful for assessing complications like parapharyngeal space involvement and vascular proximity 5 30.

Cytobacteriological Testing: Not routinely contributive in clinical practice 18.

Management

First-Line Treatment: Needle aspiration or incision and drainage under local anesthesia 13 22 66.

Antibiotics: Penicillin or amoxicillin as first-line, with metronidazole or clindamycin considered for anaerobic coverage 8 28 38.

Conservative Management: Antibiotics alone may be considered in selected pediatric cases, but drainage is often necessary 11 12 33.

Surgical Intervention: Tonsillectomy may be performed immediately or deferred based on recurrence risk and patient factors 13 27 48.

Monitoring: Close observation for complications such as airway compromise, especially in pediatric patients 7 70.

Special Populations

Pediatrics: Ultrasound is crucial for diagnosis; conservative antibiotic therapy can be effective but drainage is often required 6 11 12 66.

Elderly: Increased risk of complications; careful monitoring and prompt drainage are essential 1 66.

Comorbidities: Smoking and alcohol consumption are associated with increased risk; cessation advised 71.

Key Recommendations

Prompt Drainage: Perform needle aspiration or incision and drainage under local anesthesia for definitive treatment (Evidence: Strong 13 66).

Antibiotic Therapy: Initiate with penicillin or amoxicillin; consider metronidazole for suspected anaerobic infection (Evidence: Moderate 8 28).

Ultrasound Use: Utilize ultrasound as the primary imaging modality for diagnosis in pediatric and adult patients (Evidence: Moderate 3 5 35).

Monitor for Complications: Closely monitor patients, especially children, for airway compromise and other severe complications (Evidence: Moderate 7 70).

Consider Tonsillectomy: Evaluate the need for immediate or interval tonsillectomy based on recurrence risk and patient factors (Evidence: Moderate 13 27 48).
