title: Surgical techniques for the dissection of encased perforators in giant clinoidal meningiomas.
abstract: BACKGROUND
  Surgical treatment of giant clinoidal meningiomas remains a challenging task for neurosurgeons. Here, we present details of the surgical techniques for the dissection of encased perforators.
  
  
  METHODS
  The dissection of encased perforators is summarized as follows: (1) split the tumor above the encased arteries and perforators; (2) find the entrance and exit points of the perforators, and estimate the running course of the perforators within the tumor; (3) dissect and expose the perforators along the estimated line.
  
  
  CONCLUSIONS
  The surgical techniques described in this article will aid in achieving maximum tumor resection while preserving encased perforators.
