A case of multiple abnormalities with eustachian tube obstruction by a protruded internal carotid artery.
We report a case of multiple abnormalities with eustachian tube obstruction by a protruded internal carotid artery. A 10-year-old male presented with multiple abnormalities including anomalous pinna, poor eyesight, facial palsy, moderate conductive deafness, and otitis media with effusion. Temporal bone computed tomography demonstrated obstruction of the right eustachian tube by a protruded internal carotid artery. Insertion of a tympanostomy tube did not improve his hearing, indicating a possible ossicular chain anomaly. Although tympanoplasty is necessary to improve the patients' hearing, the poor drainage function makes this difficult. Knowledge of this vascular anomaly is important when performing myringotomy or tympanoplasty.
