Upper airway obstruction in neonates and infants with CHARGE syndrome

Area of Science:

• Pediatric Otolaryngology
• Neonatal Airway Management
• Genetics and Rare Diseases

Background:

• Upper airway obstruction is a critical concern in neonates and infants with CHARGE syndrome.
• Intubation is common, but decisions regarding tracheotomy lack clear criteria.
• CHARGE syndrome is associated with laryngeal malformations and cranial nerve dysfunction.

Purpose of the Study:

• To identify specific fiberoptic laryngoscopy findings that predict the need for tracheotomy in infants with CHARGE syndrome.
• To differentiate airway obstruction causes in CHARGE syndrome beyond laryngomalacia.

Main Methods:

• Fiberoptic laryngoscopy was performed on 10 infants with CHARGE syndrome (5 requiring tracheotomy).
• Assessment included laryngeal structure, vocal cord appearance, arytenoid position and movement, and salivary pooling.
• Comparison of findings between infants who were extubated and those who required tracheotomy.

Main Results:

• All infants shared laryngeal features: flattened larynx, short vocal cords, hypertrophic arytenoids, uncoordinated movements, and salivary pooling.
• Infants requiring tracheotomy exhibited an obstructive supraglottis, hindering vocal cord visualization, and had more severe salivary retention.
• These findings correlate with the need for tracheotomy when vocal cords are not visible throughout respiration.

Conclusions:

• Obstructive supraglottis and severe salivary retention are key indicators for predicting early tracheotomy in CHARGE syndrome infants.
• Supraglottoplasty may not resolve airway issues due to malformed larynx and cranial nerve deficits in CHARGE syndrome.
• Thorough evaluation for other upper airway obstructions is crucial before considering supraglottoplasty in these patients.
