Magnetic resonance imaging of the internal auditory canal.




MRI Internal Auditory Canal With and Without Contrast (Gadolinium) | East River Medical Imaging
The internal auditory meatus also meatus acusticus internus , internal acoustic meatus , internal auditory canal , or internal acoustic canal is a canal within the petrous part of the temporal bone of the skull between the posterior cranial fossa and the inner ear. The opening to the meatus is called the porus acusticus internus or internal acoustic opening. It is located inside the posterior cranial fossa of the skull, near the center of the posterior surface of the petrous part of the temporal bone. The size varies considerably. Its outer margins are smooth and rounded.



The cerebellopontine angles are normal. No mass lesion identified. The internal auditory canals, seventh and eighth cranial nerves and the internal ear structures are unremarkable. Support Radiopaedia and see fewer ads.





The opening of the IAM, the porus acusticus internus , is located within the cranial cavity, near the posterior surface of the temporal bone. The margins of the opening are smooth and rounded, and the canal is short 1 cm , running laterally to the bone. The canal narrows laterally, and the lateral boundary is the fundus, where the canal splits into three distinct openings, one of which is the facial nerve canal.
