Microsurgical Resection of Intraspinal Benign Tumors Using Non-Expansile Tubular Access.

Background: Intraspinal tumors are 10 to 15 times less common than brain tumors. The midline approach with extensive laminectomies represents the current gold-standard for resection, causing instability, muscle damage, and kyphosis among other well-known complications. Minimally invasive series reported their results using retractor-based systems.
