Area of Science:

  • Otolaryngology
  • Pediatric audiology
  • Neuroimaging

Background:

  • Semicircular canal dehiscence is a condition affecting the inner ear, often associated with auditory and vestibular symptoms.
  • While documented in adults, its occurrence in pediatric populations is infrequently reported.

Observation:

  • A 4-year-old male presented with bilateral mixed hearing loss, more severe in the left ear.
  • A computed tomography (CT) scan of the temporal bone was performed to investigate the hearing loss.

Findings:

  • The temporal bone CT scan revealed a partial dehiscence of the right posterior semicircular canal.
  • This anatomical finding indicates an abnormal opening in the bony labyrinth of the inner ear.

Implications:

  • This case represents a unique pediatric presentation of semicircular canal dehiscence.
  • The findings suggest the need for considering this condition in the differential diagnosis of pediatric hearing loss and warrant further research into its clinical and developmental impact.
