Psychosurgery

117
Psychosurgery, the surgical alteration or permanent removal of brain tissue to alleviate severe psychological conditions, stands as one of the most radical and controversial treatments in the history of mental health care. Its development and application have evolved significantly, marked by dramatic shifts in scientific understanding and ethical perspectives.
Historical Development of Psychosurgery
In the 1930s, Portuguese neurologist Antonio Egas Moniz introduced a surgical procedure designed...

  • Skull Base Surgery

Background:

  • Expanded endonasal approaches (EEAs) are transforming the surgical management of skull base pathologies.
  • Traditionally challenging neurovascular structures are now accessible via these endoscopic corridors.
  • Advances in surgical techniques and routes enhance visualization and access to the ventral skull base.

Approach:

  • This review provides a comprehensive anatomical appraisal of neurosurgical anatomy through endonasal and paranasal sinus routes.
  • Focus is placed on common EEAs and recent advancements in the field.
  • Emphasis is placed on the critical role of understanding surgical anatomy for effective intervention.

Key Points:

  • EEAs offer novel surgical corridors for treating complex skull base conditions.
  • Improved visualization and access to ventral skull base pathologies are key benefits.
  • Understanding the intricate surgical anatomy is paramount for successful outcomes.

Conclusions:

  • Mastery of the surgical anatomy of EEAs is essential for effective management of complex skull base pathologies.
  • Comprehensive anatomical knowledge of these corridors and surrounding neurovascular structures is crucial.
  • Maximizing the benefits of EEAs and improving patient outcomes depend on anatomical expertise.
