Summary
The middle fossa transpetrous approach offers successful surgical access to petroclival and prepontine lesions. This technique preserves hearing, labyrinthine, and facial function in selected patients.
Area of Science:
- Neurosurgery
- Skull Base Surgery
- Otolaryngology
Background:
- Surgical access to the anterior temporal bone, medial to the petrous carotid artery, poses a long-standing challenge.
- Various surgical approaches have been developed to address lesions in this complex region.
Purpose of the Study:
- To report the experience with the middle fossa transpetrous approach for treating petroclival and prepontine lesions.
- To discuss extensions of this technique, including tentorial transection and the retrolabyrinthine approach.
Main Methods:
- The middle fossa transpetrous approach was utilized for surgical treatment.
- Tentorial transection and retrolabyrinthine approaches were considered for extended access.
Main Results:
- The middle fossa transpetrous approach provided adequate surgical exposure for petroclival and prepontine lesions.
- The technique successfully maintained hearing, labyrinthine, and facial nerve function in appropriately selected cases.
Conclusions:
- The middle fossa transpetrous approach is a viable option for specific skull base lesions.
- Careful patient selection is crucial for preserving neurological function while achieving surgical goals.
