Perhaps no technology has captured the public’s imagination more than the laser. Currently, several surgeons and non-surgeons are aggressively marketing “laser spine surgery” as a means to remove disk material with the goal of decompressing a nerve to improve pain.
While there is clearly a tremendous amount of promotional energy behind this effort, the fact remains there is a significant lack of medical data to support the surgical reliability and safety of the techniques.
In contrast to the tens of thousands of Google results responding to “laser spine surgery,” a recent search on PubMed, a database of established and peer reviewed medical literature, returned only 135 results. And what’s most important is that not one of the listings offered a study of contemporary outcomes.
Laser Spine Surgery Approaches
There are two laser-assisted techniques currently in practice.
- The first involves the insertion of a fiber optic endoscope into the spinal canal through openings in the sacrum and vaporization of disk’s protrusions.
- The second involves a tiny incision or needle hole placed oblique to the spine, through which the disk is accessed and then incised with a laser.
Advocates of these approaches consider them for disk protrusions; that is, disk bulging without extrusion or significant spinal stenosis. They maintain that removal of even a small amount of disk with a laser will produce a disproportionately larger drop in intradiscal pressure in the disk protrusion, helping to relieve pressure on the nerve indirectly.
Laser Spine Surgery vs. Minimally Invasive Spine Surgery
- Laser Spine Surgery is typically performed through an incision of 7 mm or less, as compared with the 25 mm (approximately one inch) incision commonly used for microdiskectomy.
- Laser approaches are less adept at visualizing and directly decompressing a compressed nerve. Further, they lack the adaptability to manage unexpected bleeding, a cerebrospinal fluid leak or an unforeseen disk extrusion.
- Laser procedures are not effective in removing a larger portion of disk material and not applicable to treating sizable disk herniations or disk herniations with significant spinal canal narrowing known as stenosis.
- The ultimate effectiveness and safety of both laser-assisted approaches are not established by the mainstream neurosurgical community.
- Minimally invasive surgery offers a safer, more proven and versatile treatment option.
While the majority of disk herniations in our neurosurgical practice are effectively managed nonsurgically, a disk herniation performed by our neurosurgeons have the added benefit of our years of experience and refinements in technique. Our patients are routinely sent home the day of surgery with a 90%-95% success rate in the relief of their nerve pain.
