Peritonsillar Abscess and Severe Obstructive Sleep-Disordered Breathing Diagnosis and Management

Clinical Presentation and Diagnosis

The American College of Physicians recommends urgent evaluation for patients presenting with severe symptoms such as muffled voice, drooling, new-onset snoring, and significantly enlarged tonsils, even in the absence of fever, to rule out peritonsillar abscess, parapharyngeal abscess, or other serious throat infections 1
Patients with severe pharyngitis, particularly adolescents and young adults, should be suspected of having Lemierre syndrome, a rare but life-threatening condition caused by Fusobacterium necrophorum 1
The presence of severe odynophagia, muffled voice, drooling, and bilateral tonsillar enlargement strongly suggests peritonsillar or parapharyngeal abscess 1
New-onset snoring and nocturnal drooling indicate acute upper airway obstruction, which can be caused by +3 bilateral tonsillar enlargement even without infection 2

The American Academy of Otolaryngology recommends diagnostic testing, including rapid antigen detection test (RADT) or throat culture, for Group A Streptococcus if bacterial infection is suspected, although the severity of symptoms may warrant imaging regardless of test results 3, 4
CT scan with contrast is recommended if peritonsillar or parapharyngeal abscess is suspected to guide surgical drainage 1

The American Academy of Otolaryngology recommends tonsillectomy for children with obstructive sleep apnea documented by symptoms of airway obstruction, and this patient may require urgent or semi-urgent tonsillectomy given the severity of symptoms 2
Broad-spectrum intravenous antibiotics are recommended for patients with peritonsillar abscess, and hospital admission for airway monitoring may be necessary 1
Penicillin V 250-500 mg orally 2-3 times daily for 10 days is recommended for patients with Group A Streptococcus confirmed, although the severity of symptoms makes uncomplicated pharyngitis unlikely 3

The absence of fever should not be dismissed, as peritonsillar abscess and severe airway obstruction can occur without fever 1
Empirical treatment with oral antibiotics alone is not recommended, and urgent evaluation for surgical drainage is necessary if abscess is present 1
Delaying imaging, such as CT scan, is not recommended if deep space infection is suspected 1
Close monitoring of the airway is crucial, as life-threatening obstruction can develop, especially in children with smaller airways 1
