Last Updated: September 29, 2018
For general consideration, diagnosis, evaluation, indications for the procedure and preoperative considerations related to colloid cysts, please refer to the chapter on Colloid Cyst: Transcallosal Approach.

These tubular retractor systems are more likely to spread and displace subcortical tracts (parafascicular dissection) rather than transecting them.
The minimum size diameter of the retractor tube that allows application of microsurgical instruments and stereoscopic visio...
