Endoscopic cervical decompression

In one minute

Endoscopic cervical decompression widens the spinal canal in the neck from the back, through a keyhole incision (7 mm in our practice), by removing the thickened ligament and bone that narrow it. It is for selected people with cervical spinal stenosis (a narrowing of the canal the spinal cord runs through) whose compression comes from behind or from the side, including some with early myelopathy (spinal cord dysfunction: clumsy hands, unsteady walking). When the cord is squeezed from the front by a calcified disc or a large central herniation, the posterior endoscope is contraindicated and ACDF (anterior cervical discectomy and fusion), corpectomy or an open posterior operation is used instead. Operating time averaged about 96 minutes across the myelopathy series pooled in a 2023 review; most of our decompression patients walk the same day and go home within 24 hours.

What the operation is

The literature calls it posterior endoscopic cervical laminotomy or full-endoscopic posterior cervical decompression (PECD); case series describe freeing both sides through one keyhole (a unilateral approach for bilateral decompression). Biportal (UBE, unilateral biportal endoscopic) versions use two portals.

What comes out: the inner edge of the lamina (the bony roof of the canal), the thickened or calcified yellow ligament (ligamentum flavum) beneath it, and bone spurs at the joint. Most of the facet joint stays and nothing is implanted. The open alternatives are laminoplasty (the lamina is hinged open and held with small plates), laminectomy with fusion (the laminae are removed and the levels fixed with screws) and ACDF from the front.

Who it is for

The endoscope suits stenosis where the narrowing comes from the back or the side: a thick or calcified ligament, enlarged facet joints, foraminal stenosis (narrowing of the nerve opening) at one or two levels, and selected mild myelopathy where the cord is compressed mainly from behind.

Patient selection decides everything. The Neurospine technical review states that myelopathy caused by an anterior disc herniation or calcification is a contraindication for the posterior endoscopic technique, because attempting it can worsen the compression with a risk of spinal cord injury. Many myelopathy cases therefore need ACDF, a corpectomy, laminoplasty or laminectomy with fusion. Instability and a forward-bent neck also send the case to open surgery.

The 2017 guideline from AO Spine and the Cervical Spine Research Society (CSRS) frames the timing. It recommends surgery for moderate and severe degenerative cervical myelopathy. For mild myelopathy it suggests offering surgery or a supervised trial of structured rehabilitation; if the non-operative path is chosen, it recommends surgery on neurological deterioration and suggests surgery if the patient fails to improve. For cord compression on MRI (magnetic resonance imaging) without signs or symptoms of myelopathy or radiculopathy, it suggests not offering prophylactic surgery, with counselling about the risk of progression and clinical follow-up.

How it is done

You lie face down with the head fixed and the neck slightly flexed. The published technique (the Neurospine technical note) uses general anaesthesia with nerve monitoring prepared; in our practice the anaesthetist and surgeon decide per patient.

An X-ray marks the level. Through a small incision beside the midline (7 mm in our practice, under 1 cm in the published technique), dilators pass between the muscles to where the lamina meets the facet and a working tube docks there. Under the endoscope, with saline irrigation keeping the view clear, a fine burr thins the lamina until the ligament shows, and the ligament is lifted off the dura (the membrane around the cord). The surgeon watches for the dura to expand and pulsate freely, withdraws the tube and closes with one stitch; a second level gets a second small incision.

Endoscopic compared with open surgery

The evidence for endoscopic cord decompression is thinner than for lumbar surgery or cervical radiculopathy, and that needs saying first. The 2023 systematic review found 183 patients with cervical spondylotic myelopathy treated fully endoscopically: improved function and no major complications, on what its authors call scarce evidence.

A 2026 study compared 45 endoscopic canal decompressions with 50 laminoplasties for two-level myelopathy: clinical scores were similar at every follow-up, the endoscopic operation was shorter (113 versus 141 minutes) with a fraction of the drainage (32 versus 212 mL), no severe complication occurred in either group, and laminoplasty opened the canal wider at C5 to C7.

A 2026 meta-analysis of 10 studies and 862 patients compared full-endoscopic posterior decompression with ACDF for radiculopathy and myelopathy: similar disability and arm pain at final follow-up, a stay 1.6 days shorter, about half the risk of complications, no difference in reoperation, and slightly better long-term neck pain after ACDF.

For the open posterior operations, a 2016 meta-analysis of 23 studies found laminoplasty and laminectomy with fusion equally effective, with fewer C5 nerve palsies after laminoplasty, and notes that anterior surgery becomes riskier once three or more levels are involved.

Risks and how we reduce them

The 2025 systematic review of full-endoscopic cervical surgery reports dural tears in 3 to 6% of posterior operations, transient neurological deficits in 3 to 5% and revision in 4 to 6%; an epidural haematoma (a blood clot pressing on the cord) occurred in 1 of 252 patients in one series. C5 palsy, a temporary weakness of the shoulder from the fifth cervical nerve root, is a known complication of every posterior cervical operation. Incomplete decompression is the specific risk of a keyhole. Spinal cord injury is the rarest and gravest risk, which is why anterior compression is excluded. Conversion to an open operation is possible.

How the risks are reduced: the published protocol reads the MRI with a CT (computed tomography) to see where the compression sits and whether it is calcified, excludes anterior compression from the posterior endoscopic approach, and operates under general anaesthesia with nerve monitoring prepared. In our practice the anaesthetist and surgeon decide the anaesthesia per patient, and we offer ACDF and disc replacement when the anatomy calls for an anterior operation. Across all the team's operations our complication figure is well below 1%; our own number, not a comparison.

Recovery, week by week

What the evidence says

The AO Spine and CSRS guideline (Fehlings and colleagues, 2017) recommends surgery for moderate and severe myelopathy, suggests surgery or a supervised trial of structured rehabilitation for mild disease, and suggests not offering prophylactic surgery for cord compression without signs or symptoms of myelopathy or radiculopathy.

The 2023 World Neurosurgery review shows that anterior transcorporeal and posterior endoscopic techniques have treated 183 reported myelopathy patients with acceptable complications, on evidence its authors describe as scarce.

The 2026 endoscopic-versus-laminoplasty study and the 2026 endoscopic-versus-ACDF meta-analysis suggest similar outcomes with faster early recovery for the endoscope in selected patients; the meta-analysis authors write that ACDF remains the standard for complex cases.

How we do it at spine.uz

We are Tashkent's first endoscopic spine team, five surgeons operating as one, with 27,600+ endoscopic and spine operations. Cervical pages are reviewed by Dr. Akhror Yakubov, neurosurgeon. We operate on all levels, including multilevel cervical cases, treat the full range of surgical spine pathology, and offer ACDF and disc replacement when a case needs an anterior operation. Endoscopic decompression uses a 7 mm incision and no implants; most patients walk on the day of surgery and go home within 24 hours; most endoscopic decompressions are done under local anaesthesia with sedation, the anaesthetist and surgeon deciding per patient.

Send your MRI on Telegram or WhatsApp; a doctor from the team replies by voice within 48 hours, free of charge. After surgery you receive a written conclusion and follow-up on Telegram.

Preparing for the operation

Send every slice of the cervical MRI and any CT ahead, and bring the originals with your medicines list; tell the surgeon about blood thinners so they can be paused safely. Expect fasting from the night before and someone to accompany you home.
