Skull Base Techniques for Senior Residents-Designing a Posterolateral Skull Base Approach: Presigmoid vs. Retrosigmoid Approaches

Designing a Posterolateral Skull Base Approach: Presigmoid vs. Retrosigmoid Approaches

Video Transcription

Video Summary

In the video, the presenter discusses different approaches for neurosurgery, specifically focusing on the posterior petrosectomy approach. They explain that in most cases, surgeons think of the bone as an obstruction that needs to be removed to reach the area they need to operate on. However, for otologists, the bone itself is of interest and needs to be dissected. The presenter discusses the advantages and disadvantages of the posterior petrosectomy approach, highlighting its ability to provide a direct lateral view of the brainstem and shorten the working distance. They also mention specific cases that are suitable for this approach, such as brainstem cavernous malformations and certain tumors. The presenter emphasizes the importance of considering factors such as the location of the pathology and the patient's deficits and preferences when deciding on the surgical approach. They also discuss potential risks and complications associated with the posterior petrosectomy approach. The presenter concludes by thanking the event organizer and inviting the audience to an upcoming conference. No credits are mentioned in the video. The video is a recording of a lecture given by the presenter.
