Endoscopic Spine Surgery in Pasadena, CA

If you live in Pasadena and an MRI has shown a herniated disc or a pinched nerve, you have probably been told that surgery means a multi-inch incision, a hospital stay, weeks of recovery, and a long break from work. That has not been true for years — at least not for the right candidates. Endoscopic spine surgery is the most minimally invasive surgical option for many of these problems, and Dr. Kambiz Hannani has been performing endoscopic procedures from his West Covina office, about 25 minutes southeast of Pasadena, for over two decades. For the right patient, going home the same afternoon and returning to a desk job within a week is the realistic outcome.

The reason this matters specifically for Pasadena patients: the local hospitals (Huntington, USC Verdugo Hills, City of Hope) are excellent, but endoscopic spine surgery is a sub-specialized technique that not every spine surgeon performs routinely. Many surgeons still default to microdiscectomy or open techniques because that is what they trained on. If your problem can be solved through an 8-millimeter incision instead of a 1-inch one, the difference in recovery is real — and worth the 16-mile drive.

What is Endoscopic Spine Surgery?

Endoscopic spine surgery is a category of ultra-minimally invasive procedures that use a thin tube (endoscope) with a camera and light source to access the spine through a single small puncture — typically 7 to 10 millimeters wide, about the size of a pencil eraser. The surgeon watches the procedure on a high-definition monitor and uses specialized micro-instruments passed through the same tube to do the actual work.

Compared with traditional open spine surgery (which uses a 4 to 6 inch incision and dissects through layers of muscle) or even microsurgery (which uses an operating microscope and a 1 to 2 inch incision), endoscopic surgery causes dramatically less tissue damage. Less tissue damage means less pain after surgery, less blood loss, lower infection risk, and a much faster recovery.

Common Endoscopic Procedures

Not every spine procedure can be done endoscopically — but the list of what can is growing every year. The most common endoscopic procedures Dr. Hannani performs include:

• Endoscopic discectomy — removal of a herniated disc fragment compressing a nerve, in the lumbar (low back) or cervical (neck) spine

• Endoscopic foraminotomy — opening up the bony tunnel where a nerve exits the spine, relieving pinched-nerve pain

• Endoscopic laminotomy / decompression — relieving spinal canal narrowing (stenosis) without a large open laminectomy

• Endoscopic rhizotomy — targeted treatment of facet joint nerves causing chronic back pain

Endoscopic vs. Open vs. Microsurgery: A Real Comparison

A patient with a typical lumbar herniated disc has three reasonable surgical options. Here is the practical difference:

• Open discectomy — 3 to 4 inch incision, muscle dissection, often a hospital stay, 4 to 6 weeks before desk work, 8 to 12 weeks before heavy activity. Largely outdated for routine herniated discs.

• Microdiscectomy — 1 inch incision, less muscle damage, usually outpatient, 1 to 2 weeks before desk work, 4 to 6 weeks before heavy activity. The most common modern option.

• Endoscopic discectomy — 8 millimeter incision, almost no muscle damage, outpatient with same-day discharge, often back to desk work within a week, 3 to 4 weeks before heavy activity. The least invasive option.

For a single-level herniated disc in a healthy patient, the endoscopic approach gives outcomes equivalent to microdiscectomy with meaningfully faster recovery. For more complex spinal problems — multi-level stenosis, instability, prior failed surgery — open or fusion surgery may still be the right answer.

Why Patients in Pasadena Choose Dr. Hannani for Endoscopic Spine Surgery

Pasadena's medical landscape is dominated by larger institutions — Huntington Hospital, USC Verdugo Hills, City of Hope in Duarte. Those are excellent hospitals, but endoscopic spine surgery is a fellowship-level technique that benefits from a surgeon who does it regularly rather than occasionally. Patients from Pasadena, San Marino, South Pasadena, Altadena, Sierra Madre, and the Hastings Ranch and Bungalow Heaven neighborhoods come down to West Covina specifically because Dr. Hannani has been performing the full endoscopic spectrum — discectomy, foraminotomy, decompression, and rhizotomy — for over 20 years.

There is also a practical reason Pasadena patients gravitate toward outpatient endoscopic surgery. The driving culture of Pasadena means most patients want to be home the same day — not stuck overnight in a downtown hospital. Endoscopic procedures are designed for same-day discharge, and the West Covina facility is a quiet, low-volume environment that is genuinely set up for it.

Getting to Our Office from Pasadena

From Pasadena, the standard route is the 210 East to the 605 South to the 10 East, exiting at Citrus Avenue or Barranca in West Covina. Outside of rush hour the drive runs 25 to 30 minutes. From Hastings Ranch, the 210 East to the 57 South to the 10 West can be slightly faster. There is free on-site patient parking — useful both for the consultation and for surgery day, when a family member will be driving you home.

A Patient Story

A 39-year-old physical therapist from Altadena came in with six weeks of severe right leg pain shooting from her low back down to the outside of her right calf — classic L5 nerve root distribution. MRI showed a sequestered disc fragment at L4-L5 compressing the nerve. She had already failed two epidural steroid injections and was missing work. She underwent an outpatient endoscopic discectomy on a Wednesday morning, walked out of the surgery center that afternoon, was off Norco within 48 hours, and was back seeing her own patients the following Monday. Five days, start to finish.

Who is a Candidate for Endoscopic Spine Surgery?

The best candidates generally have:

• A clearly defined, single-level problem (one herniated disc, one pinched nerve, one stenotic level)

• Imaging that matches the symptoms — leg pain in the L5 distribution with an L4-L5 disc herniation, for example

• Failed at least 6 weeks of conservative care (physical therapy, medications, often an injection)

• No significant spinal instability or major deformity

• No history of major prior surgery at the same level (this can sometimes still be done — case-by-case)

Patients who are not endoscopic candidates are not stuck — Dr. Hannani offers the full range of spine procedures, from microdiscectomy and decompression to artificial disc replacement and fusion. The right operation is the one matched to your specific problem.

What Recovery Looks Like

For a typical endoscopic lumbar discectomy:

• Day of surgery: 30 to 60 minute procedure under sedation or light general anesthesia. Walking within an hour. Discharged home the same day — back to Pasadena that afternoon.

• Days 1-3: Mild soreness around the small incision. Most patients off narcotics within 48 to 72 hours.

• Week 1-2: Most patients return to a desk job. Driving usually permitted within a week (off narcotics).

• Weeks 3-4: Light exercise, walking, gradual return to normal activity.

• Weeks 6-12: Return to heavy lifting, sports, and physically demanding work.

Risks of Endoscopic Spine Surgery

No spine surgery is without risk. Endoscopic procedures share the same general risks as any spine surgery — infection, bleeding, nerve injury, dural tear (small leak of spinal fluid), and the possibility that symptoms do not fully resolve. The endoscopic technique generally has lower rates of these complications than open surgery because of the smaller working corridor and reduced tissue damage. The most common technical limitation is that some pathology turns out, intraoperatively, to need a slightly larger approach — Dr. Hannani will discuss this possibility honestly during your consultation.

Frequently Asked Questions from Pasadena Patients

How long is the drive from Pasadena to your West Covina office? Typically 25 to 30 minutes via the 210 East to the 605 South to the 10 East. On surgery day, plan to have a family member drive you both ways — you cannot drive yourself home after sedation. The trip back to Pasadena is comfortable in a passenger seat.

Will my insurance — including the Huntington Hospital network plans — cover endoscopic spine surgery? Yes. Endoscopic procedures are billed under standard CPT codes and are covered by most major California insurance plans, including Medicare, Blue Shield, Aetna, Cigna, United, and the PPO products commonly used by Pasadena residents. Our office handles pre-authorization on your behalf.

Can I have my endoscopic surgery done at Huntington Hospital in Pasadena instead? Dr. Hannani's primary surgical privileges are at Emanate Health and affiliated outpatient surgery centers in West Covina, where the endoscopic equipment and OR team are set up for these procedures. He does not currently operate at Huntington. Most Pasadena patients find the 25-minute drive on a single surgery day to be a reasonable trade for an experienced endoscopic surgeon and a familiar OR team — and you'll be home in your own bed in Pasadena that same evening.

How does endoscopic compare to the microdiscectomy I was offered at another Pasadena practice? Microdiscectomy is an excellent operation and the right answer for many patients. The endoscopic approach uses a smaller incision (about 8 mm vs about 1 inch) and disrupts less muscle, which usually means a faster early recovery. For a single-level herniated disc the long-term outcomes are comparable. Bring your MRI to a consultation and Dr. Hannani will tell you honestly which approach fits your anatomy best.
