Smaller incisions
Two openings of about 7 to 10 mm each, closed with a stitch or two and often barely visible once healed.

Patient Guide
Among the least invasive ways to treat many spine conditions: surgery through incisions smaller than a dime, guided by a high-definition camera.
The Basics
Endoscopic spine surgery is an advanced form of minimally invasive spine surgery. Instead of opening the back to see the spine directly, the surgeon works through one or two incisions of roughly 7 to 10 millimeters, about the width of a pencil, using a high-definition camera (an endoscope) and specialized instruments.
The camera magnifies the surgical field on a monitor, giving the surgeon a clearer, closer view of the nerves and disc than the naked eye allows. Muscles are gently moved aside through natural planes rather than cut or stripped from the bone, which is a major reason recovery is faster and less painful.
Dr. Kazarian specializes in Biportal Endoscopic Spine Surgery (BESS), a technique that uses two small portals: one for the camera and one for instruments. This preserves the freedom of movement of traditional surgery while keeping the footprint of the operation small.
Endoscopic vs. Traditional Surgery
The clearest way to understand endoscopic surgery is to compare it with traditional open spine surgery, where the spine is exposed through a larger incision.
| Category | Traditional Open Surgery | Endoscopic (BESS) |
|---|---|---|
| Incision size | A single incision of roughly 2 to 6 inches | Two incisions of about 7 to 10 mm each |
| Muscle handling | Muscles are stripped from the bone to expose the spine | Muscles are gently dilated, not cut |
| Visualization | Direct view with the naked eye or surgical loupes | High-definition camera inside the spine, with constant fluid irrigation for a clear view |
| Blood loss | Higher | Typically minimal |
| Hospital stay | Often several days | Often same-day discharge |
| Return to daily activity | Often measured in months | Often measured in weeks |
| Scarring | A long visible scar | Two small marks that often fade substantially |
Every patient and condition is different. These are typical ranges, not guarantees, and the right operation for you depends on your diagnosis and anatomy. Dr. Kazarian will review which approach fits your situation at your consultation.
Benefits
Two openings of about 7 to 10 mm each, closed with a stitch or two and often barely visible once healed.
The muscles that support your spine are moved aside, not cut, preserving the strength you'll rely on during recovery and for years afterward.
Because less tissue is disrupted, most patients need significantly less pain medication after surgery.
Many patients walk within hours of surgery and return to desk work in one to two weeks.
Most endoscopic decompressions are outpatient procedures, so you can sleep in your own bed the night of surgery.
The endoscope magnifies the nerves and disc on a high-definition monitor, letting the surgeon see fine detail up close.

No. "Laser spine surgery" is largely a marketing term, and lasers play little role in modern spine care. Endoscopic spine surgery is a rigorously studied surgical technique that uses a camera and precision instruments to directly remove the disc fragment, bone spur, or thickened ligament compressing a nerve.
Endoscopic techniques treat many of the most common spine problems, including disc herniations, spinal stenosis, and some cases requiring fusion. Candidacy depends on your specific anatomy, imaging, and symptoms. Dr. Kazarian reviews every patient's MRI personally to determine whether an endoscopic approach is appropriate.
For appropriately selected patients, published studies report that endoscopic decompression achieves relief comparable to open and microscopic techniques, with less blood loss, shorter hospital stays, and faster early recovery. The goal of the surgery (removing pressure from the nerve) is the same; the difference is how much healthy tissue is disturbed along the way.
Most patients walk within a few hours of surgery. Many return to desk work within one to two weeks and to more physical work in four to six weeks. Driving typically resumes once you are off pain medication and can move comfortably, often within one to two weeks. Your timeline depends on the specific procedure and your recovery.
Common indications include lumbar disc herniations, sciatica, spinal stenosis, bone spurs compressing nerves, and pinched nerves in the neck. Endoscopic techniques can also be combined with fusion (endoscopic TLIF) for patients with instability or spondylolisthesis.
Endoscopic spine procedures at NYU Langone are typically performed under general anesthesia. Because the operation is less disruptive, anesthesia times are shorter and recovery from anesthesia is usually smoother than with open surgery.
