Upper airway obstruction in infectious mononucleosis
Insights
Infectious mononucleosis can cause dangerous airway obstruction due to throat swelling. Prompt tonsillectomy is recommended for severe cases, while corticosteroids manage milder symptoms.
Area of Science:
- Otolaryngology
- Pediatric Infectious Diseases
- Critical Care Medicine
Background:
- Infectious mononucleosis (IM) is typically a benign viral illness.
- Rarely, IM can lead to severe upper airway obstruction.
- This obstruction is primarily due to pharyngeal lymphoid hyperplasia and edema.
Observation:
- A case of a child with IM presenting with hypersomnolence, sleep apnea, and stridor.
- Retrospective analysis of 72 cases of respiratory complications in IM.
- Guidelines for airway management in IM-related respiratory compromise were developed.
Findings:
- Mild airway obstruction with fever, odynophagia, and malaise treated with parenteral corticosteroids.
- Severe airway occlusion managed with immediate tonsillectomy.
- Tracheotomy reserved for progressive alveolar hypoventilation, hypercarbia, atelectasis, and bulbar paralysis.
Implications:
- Tonsillectomy is effective in resolving airway obstruction and improving swallowing in IM patients.
- Early recognition and appropriate airway management are crucial for preventing severe outcomes.
- This study provides a framework for managing respiratory complications of infectious mononucleosis.
Abstract:
Life-threatening upper respiratory obstruction is an unusual complication of infectious mononucleosis. Although the majority of fatalities result from progressive bulbar paralysis or the Guillain-Barré syndrome, airway impairment primarily occurs as a result of pharyngeal lymphoid hyperplasia and associated faucial arch edema. Recent experience in a young child with infectious mononucleosis who exhibited progressive hypersomnolence, sleep apnea, and stridor during sleep is presented. In addition, a retrospective analysis of 72 cases of respiratory complications of infectious mononucleosis provides guidelines for specific airway management. Mild upper respiratory obstruction with persistent fever, severe odynophagia, and malaise is treated with parenteral corticosteroids. Immediate tonsillectomy using a halothane and oxygen induction technique is recommended for severe airway occlusion. Tracheotomy is currently reserved for those patients with progressive alveolar hypoventilation, hypercarbia, atelectasis, and bulbar paralysis. In general, tonsillectomy is well-tolerated, eliminating airway obstruction, improving swallowing function, and rapidly resolving pharyngeal discomfort.

Chronic Pharyngitis
Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...
