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.
我们报告一例因颈内动脉突出导致咽鼓管阻塞的多重异常病例。一名10岁男性出现多种异常，包括耳廓异常、视力不佳、面瘫、中度传导性耳聋以及渗出性中耳炎。颞骨计算机断层扫描显示右咽鼓管被突出的颈内动脉阻塞。鼓膜置管并未改善其听力，提示可能存在听骨链异常。尽管鼓室成形术对于改善患者听力是必要的，但引流功能不佳使其难以实施。在进行鼓膜切开术或鼓室成形术时，了解这种血管异常情况很重要。
