Study Notes
Peritonsillar Abscess
- Medial displacement of the uvula, palatine tonsil, and anterior pillar can be seen in acute peritonsillar abscess
- Culture of pus from abscess drainage confirms diagnosis
- Imaging is not necessary to confirm diagnosis, but CT with IV contrast (LR+ 4, LR- 0) and intraoral ultrasonography (sensitivity 89-95%, specificity 79-100%) can be used
- Treatment includes drainage, antibiotic therapy, and supportive care
- Peritonsillar abscess is the most common deep infection of the head and neck (30% of abscesses), usually begins as acute tonsillitis → cellulitis → abscess formation
- Polymicrobial infection with common organisms: Group A streptococci, Staphylococcus aureus, Haemophilus influenzae, Fusobacterium, Peptostreptococcus, Pigmented Prevotella species, Veillonella
Clinical Presentation of Peritonsillar Abscess
- Severe unilateral sore throat
- Dysphagia and odynophagia leading to pooling of saliva or drooling
- Fever and malaise
- Dysphonia: muffled “hot potato” voice
- Rancid or fetor breath
- Otalgia
- Trismus (66% of patients)
- Oropharyngeal exam: erythematous enlarged tonsil and bulging soft palate on affected side, uvular deviation to contralateral side
- May have severely tender cervical lymphadenopathy
Retropharyngeal Abscess
- Retropharyngeal edema due to cellulitis and suppurative adenitis of lymph nodes in retropharyngeal space
- Preceded by upper respiratory infection, pharyngitis, otitis media, or wound infection following penetrating injury to posterior pharynx
- Peak incidence in 3-5 year olds
- Observed as prevertebral soft-tissue thickening on lateral X-ray of neck
- Treat as impending airway emergency, requires antibiotic therapy, and possible surgical consultation for needle aspiration or incision and drainage
Clinical Presentation of Retropharyngeal Abscess
- Sore throat and dysphagia
- Fever
- Drooling
- Dysphonia (muffled voice)
- Neck stiffness; limited neck ROM (especially hyperextension)
- Stridor
- May see bulging of the posterior wall of oropharynx on clinical examination
Complications of Pharyngitis
- Non-suppurative complications: acute rheumatic fever (ARF), poststreptococcal glomerulonephritis, pediatric autoimmune neuropsychiatric disorder associated with group A streptococcal (PANDAS) infection
- Suppurative complications: peritonsillar abscess, retropharyngeal abscess, otitis media, sinusitis, mastoiditis, cervical lymphadenitis, meningitis, bacteremia
