Area of Science:

  • Neurosurgery
  • Surgical Oncology

Background:

  • The occipital approach, first described by James Poppen in 1966, is a key technique for accessing deep-seated tumors.
  • It provides a wider surgical view compared to the supracerebellar transtentorial approach.

Purpose of the Study:

  • To demonstrate the technical nuances of the occipital transtentorial approach.
  • To showcase the exoscopic dissection of a pineal gland tumor.

Main Methods:

  • Surgical video demonstration of the occipital transtentorial approach.
  • Utilizing an exoscope for tumor dissection.
  • Case presentation of a 66-year-old male with a pineal gland tumor.

Main Results:

  • The exoscope offers ergonomic advantages over traditional microscopes.
  • Improved surgical workflow was observed with exoscopic use.
  • Successful dissection of a pineal gland tumor was achieved.

Conclusions:

  • The occipital transtentorial approach is a valuable method for pineal tumor resection.
  • Exoscopic technology enhances surgical ergonomics and efficiency in neurosurgery.
