Area of Science:

  • Vascular anatomy
  • Otolaryngology
  • Embryology

Background:

  • Aberrant internal carotid artery in the middle ear is a known but uncommon finding.
  • Understanding its embryological basis is crucial for diagnosis and management.

Observation:

  • This case presents a rare bilateral aberrant intratympanic carotid artery.
  • Additionally, unilateral duplication of the cervical and petrous internal carotid artery was observed, rejoining the main artery within the petrous portion.

Findings:

  • The study reviews literature on aberrant internal carotid artery in the middle ear.
  • It discusses embryological and anatomical features, and diagnostic approaches for this rare vascular anomaly.

Implications:
