Isolated temporary pharyngeal paralysis in childhood

Area of Science:

• Neurology
• Pediatrics
• Infectious Diseases

Background:

• Cranial nerve palsies can manifest with diverse neurological symptoms.
• Isolated involvement of the ninth and tenth cranial nerves is uncommon in pediatric populations.

Observation:

• Three pediatric patients presented with dysphagia (difficulty swallowing) and rhinolalia (nasal speech).
• These symptoms indicated isolated paralysis of the glossopharyngeal (ninth) and vagus (tenth) cranial nerves.

Findings:

• The children demonstrated complete clinical recovery within a three-to-four-week period.
• The observed clinical presentation strongly suggested an infectious etiology for the cranial nerve paralysis.

Implications:

• This case series highlights a potential infectious cause for isolated ninth and tenth cranial nerve palsies in children.
• Prompt recognition and understanding of infectious triggers are crucial for managing pediatric cranial nerve dysfunction.
