Term Detail
MP term:abnormal internal auditory canal morphology
Synonym: abnormal internal acoustic meatus morphology
Synonym: abnormal internal auditory meatus morphology
Synonym: abnormal meatus auditorius internus morphology
MP id: MP:0004286
Definition: any structural anomaly in the canal beginning at the opening of the internal acoustic meatus in the posterior cranial fossa, passing laterally through the petrous portion of the temporal bone to end at the fundus, where a thin plate of bone separates it from the vestibule; it gives passage to the facial and vestibulocochlear nerves together with the labyrinthine artery and veins
