What is cervical laminectomy?
A cervical laminectomy is a surgical procedure performed on the cervical (neck) region of the spine. The spinal canal is protected by a series of bones called vertebrae. A part of each vertebra bone called the lamina abuts the lamina of adjacent vertebrae to form a bony, flexible tube (spinal canal).
In a cervical laminectomy, the laminae of a cervical vertebra are removed to widen the spinal canal and relieve the pressure on the spinal cord and nerves.
Is cervical laminectomy a major surgery?
A cervical laminectomy can take1 to 3 hours to perform. It is a major spine surgery in a sensitive location on the backbone. It is usually performed only when symptoms are not relieved with non-invasive therapies such as:
- pain relievers
- physical therapy
- epidural or nerve sheath injections
It is generally considered a safe surgery, especially with the current technological advancements in the field of spinal surgery.
When is a cervical laminectomy performed?
The spinal cord and spinal nerves run through the spinal canal formed by the laminae. When this space narrows, it compresses the spinal cord and irritates the nerve roots. This may result in conditions known as radiculopathy or myelopathy, which cause:
A cervical laminectomy relieves nerve compression caused by spinal canal narrowing. It may be useful for patients with:
- degenerative disc disease
- spinal stenosis
- cervical spondylosis
- bulging or prolapsed disc
- bone spurs in the spine
- trauma to the spine
Cigarette smoking, frequent lifting, and diving are additional risk factors for cervical myelopathy.
How is a cervical laminectomy performed?
An orthopedic surgeon or neurosurgeon performs the cervical laminectomy under general anesthesia.
- The patient undergoes blood and imaging tests prior to the surgery.
- The patient must stop taking blood thinners, have nothing to eat or drink 8 hours prior to surgery, and check with the doctor before taking any regular medications.
- The patient lies flat on their abdomen during the procedure.
- The anesthetist administers the anesthesia and monitors the patient’s vital functions during the surgery.
- The surgeon makes an incision in the skin over the cervical vertebra that requires laminectomy.
- The surgeon removes a section of the vertebra called lamina. Where possible, they may just cut one side of the lamina to widen the space for spinal nervous tissue.
- The surgeon may also remove bone spur and damaged disc tissue.
- Sometimes the surgeon may also fuse two or more vertebrae to provide stability.
- The surgeon closes the incisions with sutures.
- The anesthesiologist brings the patient out of anesthesia and keeps them under observation until stable.
- The patient may be discharged in two or three days.
How long does it take to recover from a cervical laminectomy?
Post-surgery the patient is encouraged to walk within a day or two, and slowly increase activities as tolerated.
The patient may require a neck brace to support the neck while healing for two to six weeks, depending on the number of vertebrae operated upon.
- Patients should avoid heavy lifting and strenuous activities during recovery.
- Physical therapy and rehabilitation might be required after healing is complete.
- Patients should be able to resume normal activities in six to eight weeks.
What are the risks and complications of a cervical laminectomy?
Cervical laminectomy is generally a safe procedure and most people heal from it with no significant problem. As with any major surgical procedure, cervical laminectomy has risks that include:
- anesthesia side effects like headache, nausea and confusion
- infection at the surgery site
- bleeding and blood clots
- injury to spinal cord, nerve roots or blood vessels
- leakage of cerebrospinal fluid
- failure of surgery to provide symptom relief
- aggravation of original symptoms
- kyphosis or excessive curve of the spine
- loss of bowel and bladder control, and impotence
- rarely, stroke and paralysis
How dangerous is a cervical laminectomy?
Major complications from a cervical laminectomy are unusual, but do occur as listed above. Advancement in medical technology and surgical techniques have resulted in reducing risks to a great extent. About 90 percent of patients come out of the surgery with no complications.
What is the success rate of a cervical laminectomy?
Studies indicate that a majority of patients have symptom relief after a cervical laminectomy. The success of the procedure also depends on the degree of the patient’s disease. The surgery decompresses the spinal canal and relieves the pressure on the spinal cord and nerves. It is not a cure for underlying disease like arthritis or degenerative disc disease.

Neck Pain (Cervical Pain)Neck pain (cervical pain) may be caused by any number of disorders and diseases. Tenderness is another symptom of neck pain. Though treatment for neck pain really depends upon the cause, treatment typically may involve heat/ice application, traction, physical therapy, cortisone injection, topical anesthetic creams, and muscle relaxants.
Neck Pain and DizzinessNeck pain is any degree of discomfort in the front or back of the neck between the head and the shoulders. Dizziness is characterized as either vertigo with disequilibrium or lightheadedness associated with feeling faint or the potential to lose consciousness. Causes of neck pain and dizziness vary, and treatment depends on the cause. With any unexplained or persisting neck pain or dizziness, consult with a health care professional, who can determine whether the symptoms are harmless and temporary or serious and threatening.
Causes of Neck Pain and TreatmentWhat causes chronic neck pain? If you have poor posture, bad sleep habits, or spine problems, these issues can lead to a stiff neck or other painful symptoms in your cervical spine. Learn about the most frequent causes of neck pain, including spinal stenosis, bone spurs, neck strain, and degenerative disc disease.
Shoulder and Neck PainShoulder and neck pain may be caused by bursitis, a pinched nerve, whiplash, tendinitis, a herniated disc, or a rotator cuff injury. Symptoms also include weakness, numbness, coolness, color changes, swelling, and deformity. Treatment at home may incorporate resting, icing, and elevating the injury. A doctor may prescribe pain medications and immobilize the injury.

What Is Intraoperative Neurophysiological Monitoring?Intraoperative neurophysiological monitoring is the continuous evaluation of a patient’s nervous system during surgery, especially procedures involving the brain and spinal cord. Electrical and electromagnetic sensors connected to the patient via adhesive electrodes or needles transmit information from the nervous system that can be monitored on a computer screen.
