Minimally Invasive Neurosurgery

Neurosurgeons at CMMC treat conditions within the brain and the spinal cord

Procedures may include the repair of ruptured discs in the spinal column, bleeding problems within the brain tissue or the surrounding membranes, or tumor excision, to name a few.

Minimally invasive techniques involve one or more small incisions each about a half-inch or less in length and the insertion of specialized small tube systems and retractors. The number of incisions depends on the type of surgery. The tubes allow the surgeon to insert specially designed surgical instruments inside the body in order to perform the procedure. This is often performed using 3-D real-time image-guidance. The sophisticated technology gives CMMCs surgeons great precision, flexibility and control.

When it comes to neurosurgery, these minimally invasive procedures benefit our patients in a variety of ways over open brain or open spine surgery, which requires larger incisions and are more disruptive. Through minimally invasive techniques, our patients often feel less pain, experience less or no trauma to the brain, lose less blood, receive minimal scarring, enjoy a shorter hospital stay, and return to their normal activities faster.

Cranial Base & Brain


CMMC offers a treatment alternative for people with benign and malignant tumors, many of which were previously inaccessible or required extensive operations. This minimally invasive procedure uses endoscopic navigation through the nose and nasal sinuses to gain access to the cranial base and brain, combined to 3-D real time image-guidance, for the treatment of pathological processes involving the pituitary or the skull base. Minimally invasive image-guided and endoscopic intra-cerebral procedures are also performed for the treatment of hydrocephalus (shunts, septostomy, IIIrd ventriculostomy), colloid cyst removal, and endoscopic cyst fenestration.

Spinal Procedures

CMMC neurosurgeons are particularly skilled in minimally invasive surgical procedures for the spine, helping patients with debilitating back, neck, or leg pain. Through innovative technological advancements, complex spine surgery has progressed to the extent that many patients are often walking the same day of surgery, experiencing less blood loss, spending less time in the hospital, and going back to work within two to four weeks (as opposed to two or three months). Some of the procedures offered include: Nuvasive XLIF, Nuvasive MAS-TLIF and Nuvasive MAS-PLIF procedure, which are minimally invasive procedures for the treatment of complex spinal issues requiring decompression and fusion. CMMC neurosurgeons also use various percutaneous spinal fixation techniques for traumatic and other non-traumatic conditions.
