Overview

Cervical disc disease is a collection of medical conditions that impact the spinal cord and roots, frequently seen in individuals during their third and fourth decades of life.

Although non-surgical methods are preferred, surgical intervention is only utilized in specific instances. The type of surgical procedure chosen depends on the individual patient’s cervical anatomy, the location of the herniated disc, and whether osteophyte formation is present. ‘

Cervical laminoforaminotomy is a surgical procedure aimed at relieving pressure on the spinal nerves in the neck region. This procedure is typically recommended for individuals experiencing significant nerve compression symptoms, such as pain, numbness, or weakness in the neck, shoulders, arms, or hands. Let’s break down the key aspects of this surgery and its implications in simpler terms.

 

The Basics of Cervical Spine Anatomy

The cervical spine consists of seven vertebrae in the neck, labeled C1 through C7. These vertebrae protect the spinal cord and support the head’s movement. Between these vertebrae are intervertebral discs that act as cushions, and the foramina are small openings that allow nerve roots to exit the spinal cord and travel to various parts of the body.

Why is Cervical Laminoforaminotomy Needed?

Over time, factors like aging, injury, or degenerative conditions such as arthritis can cause the foramina to narrow, a condition known as foraminal stenosis. This narrowing can compress the nerves, leading to symptoms like:

  • Chronic neck pain
  • Radiating pain into the shoulder and arm
  • Numbness or tingling in the arms or hands
  • Muscle weakness

When conservative treatments such as physical therapy, medications, or injections fail to alleviate these symptoms, cervical laminoforaminotomy may be considered.

 

The Procedure

Cervical laminoforaminotomy is a minimally invasive surgery designed to relieve nerve compression by enlarging the foramina. Here’s a step-by-step overview:

Preparation: The patient is given anesthesia to ensure they are asleep and pain-free during the procedure.

Incision: A small incision is made on the back of the neck, providing access to the affected vertebrae.

Bone Removal: The surgeon removes a small portion of the lamina (the back part of the vertebra) and any other structures compressing the nerve, such as bone spurs.

Foramen Enlargement: The foramen is then carefully enlarged to free the compressed nerve.

Closure: The incision is closed with sutures, and a bandage is applied.

At present, there are two primary methods available: anterior and posterior. The posterior approach for cervical disc herniation has become comparatively less utilized since the implementation of the anterior approach.

Despite the fact that each approach has its own set of pros and cons, both can yield positive outcomes when utilized appropriately. For the management of cervical foraminal stenosis and soft disc herniation situated in lateral positions, posterior cervical laminoforaminotomy is a successful surgical intervention for alleviating radicular pain.

Compared to anterior methods, posterior approaches utilizing keyhole laminoforaminotomy offer superior visibility of the nerve root, disc, and osteophytes. In a majority of patients experiencing pain, foraminotomy delivers good or excellent outcomes. Optimal outcomes are achieved in scenarios where there is a single level disc disease and a soft disc herniation located laterally.

The posterior approach for cervical pathologies utilizing keyhole foraminotomy, or laminoforaminotomy, although it poses less risk during both the intraoperative and postoperative periods for lateral cervical pathologies, is not as frequently employed as the anterior approach.

When it comes to cervical disc herniation and cervical spondylotic myelopathy, anterior surgery and corpectomy come with a number of drawbacks, one of which is the nearly constant need for sturdy bone grafts. Elderly individuals, smokers, and those with diabetes tend to have lower fusion rates, while complications related to grafts and adjacent segment disease are frequently observed.

Therefore, posterior surgery remains a popular option and is applicable in a broad array of surgical cases. A large percentage of cases report favorable clinical outcomes, exceeding 90%, following cervical posterior foraminotomy.

  • According to studies in the medical literature, a posterior cervical approach resulted in good to excellent outcomes (85%) among 171 patients who underwent lateral disc surgery and were followed for a period ranging from 5 to 33 years.
  • In another published study, pain relief of 96% and recovery of motor deficits of 98% were reported across 736 cases, with no discernible difference between cases of disc herniation and foraminal stenosis.
  • An additional study found in the literature involved 89 cases where cervical posterior foraminotomy was performed, and the patients were subsequently monitored for a duration of 8.6 months. According to Odom’s criteria, the results were deemed good or excellent in 95% of cases.
  • Literature has reported 162 cases, in which a 95% recovery rate of preoperative symptoms, with postoperative follow-up conducted over a period of 77 months. The study also highlighted that foraminotomy did not heighten the likelihood of kyphosis.

The keyhole foraminotomy and laminoforaminotomy are posterior cervical surgical approaches employed to remove lateral and cervical foraminal disc hernias and spurs.

Surgical procedures such as the unilateral single-level or multi-level approach and the bilateral single or multi-level (fenestration approach) can be carried out. This procedure can be accompanied by laminectomy or laminoplasty. If a patient has unilateral laminoforaminotomy at one or multiple levels, laminectomy is typically performed, but not laminoplasty.

The dorsal approach offers the advantage of being able to follow the ascending nerve root appropriately based on the level of resection, while larger facetectomy may lead to instability and necessitate fusion.

A laminoforaminotomy procedure causes less destabilization of the cervical spine compared to anterior discectomy procedures with or without fusion. In certain cases, drilling of the medial aspect of the pedicle can be performed to reduce the amount of retraction needed for the dural sac and root. Prior to surgery and after surgery, patients can undergo cervical spine imaging, which can reveal that kyphosis is not more likely to occur with laminoforaminotomy.

It has been observed that laminoforaminotomy can lead to postoperative lordosis, even in patients with flattened cervical lordosis. Rarely, kyphosis may develop during the 2nd year of postoperative follow-up, and in such cases, the patient may need to undergo subsequent surgery using the anterior approach.

There is a growing trend of using posterior cervical microendoscopic foraminotomy for managing cervical radiculopathy. The endoscopic technique for posterior cervical microendoscopic foraminotomy is gaining popularity for treating cervical radiculopathy, and it offers several advantages over the traditional keyhole approach. These include:

  • A smaller incision
  • Reduced muscle injury and blood loss
  • Decreased postoperative pain
  • A shorter hospital stay

Despite the theoretical advantages of the endoscopic technique, there is still no agreement on the optimal approach.

 

Complications

Literature reports an intraoperative complication rate of 2.2% or higher in patients who have undergone laminoforaminotomy. More frequent muscle dissection and bone removal can be observed in posterior cervical surgery compared to anterior surgery.

Therefore, one may consider posterior surgery to have a disadvantage in the form of axial neck pain. Excessive intraoperative bleeding may occur in obese patients undergoing surgery in the prone position.

Cord and brain ischemia due to hypotension may be observed in patients who undergo surgery in a sitting position. Other potential complications of this surgery include cerebrospinal fluid leakage, epidural bleeding, pneumocephalus, injury to the vertebral artery, as well as cord and root injuries.

Currently, the anterior approach is the favored method for cervical disc herniation surgery. The posterior laminoforaminotomy is a safe and effective surgical technique with low complication rates for spinal and root decompression caused by cervical disc herniation, despite the current preference for the anterior cervical approach.

A particularly suitable application for posterior laminoforaminotomy is for treating foraminal disc herniation and stenosis. This procedure has several benefits, such as

  • Excellent visualization of the nerve root
  • Minimal removal of the lamina
  • Maintaining spinal stability
  • Not requiring fusion

The success rate can be improved by selecting appropriate patients, determining the correct levels, making informed decisions for surgery, and using appropriate techniques.

 

Recovery and Outcomes

Post-surgery, patients typically experience relief from nerve compression symptoms. Recovery involves several stages:

Immediate Post-Op: Patients may experience some pain and discomfort, which is managed with medications. They are usually able to go home the same day or after an overnight stay.

Rehabilitation: Physical therapy is often recommended to help restore neck strength and flexibility.

Long-Term Care: Regular follow-ups with the surgeon ensure the spine is healing correctly and that symptoms have resolved.

Most patients can return to normal activities within a few weeks to months, depending on their individual recovery progress.

 

Conclusion

Cervical laminoforaminotomy is a valuable surgical option for individuals suffering from nerve compression in the cervical spine. By understanding the procedure, its benefits, and potential risks, patients can make informed decisions about their treatment. If you are experiencing chronic neck pain or other related symptoms, consult with a spine specialist to determine if cervical laminoforaminotomy is the right option for you.
