A 5-year-old girl with nocturnal stridor and apnea underwent successful CO2 laser arieglotoplasty for laryngomalacia. Post-surgery, she experienced facial movements, with EEG showing benign childhood epileptiform discharges.
Area of Science:
- Pediatric Otolaryngology
- Pediatric Neurology
Background:
- Laryngomalacia is a common congenital condition causing upper airway obstruction in infants.
- Adenotonsillectomy is a frequent surgical intervention for related symptoms, but may not resolve all airway issues.
Observation:
- A 5-year-old girl presented with worsening nocturnal stridor, ocular retroversion, and suspected apnea.
- Previous adenotonsillectomy did not resolve her respiratory symptoms.
Findings:
- Nasal fiberoptic endoscopy confirmed laryngomalacia as the cause of stridor.
- CO2 laser ariepiglotoplasty significantly improved the patient's airway symptoms.
- Post-operative follow-up revealed self-limited clonic facial movements during sleep onset.
- Electroencephalogram (EEG) findings were consistent with benign childhood epileptiform discharges.
Implications:
- Surgical intervention for laryngomalacia can be effective in improving airway obstruction.
- The co-occurrence of laryngomalacia and benign childhood epileptiform discharges warrants further investigation.
- This case highlights the importance of comprehensive evaluation in pediatric airway disorders.
