1. Procedure Overview
Extradural (or extramedullary) spinal tumors are located outside the spinal cord but within the spinal column, often in or around the meninges (the protective covering of the spinal cord) or in the epidural space. These tumors can cause symptoms such as pain, weakness, numbness, or difficulty walking. Surgical removal is often necessary to alleviate symptoms and prevent further neurological damage.
The surgery involves:
Tumor Resection: The surgeon removes as much of the tumor as possible while protecting the surrounding nerve roots and spinal cord.
Posterior or Anterior Approach: Depending on the tumor’s location, the surgery may be performed from the back (posterior) or front (anterior) of the spine.
Microsurgical Techniques: In many cases, a microscope is used to enhance precision and minimize damage to healthy tissue.
The goal is to remove the tumor and decompress the spinal cord or nerve roots to restore function and alleviate pain.
2. Type of Anesthesia
Extradural spinal tumor surgery is performed under general anesthesia.
3. Possible Risks and Complications
Infection
Bleeding
Nerve damage or spinal cord injury
Dural tear (spinal fluid leak)
Recurrence of the tumor
Damage to the surrounding vertebrae or nerve roots
Anesthesia-related complications
4. Hospital Stay Duration
The typical hospital stay is 3 to 5 days, depending on the complexity of the surgery and the recovery rate of the patient.
5. Important Post-Operative Car
Pain management and wound care
Physical therapy to restore strength, mobility, and function
Avoidance of heavy lifting or excessive strain for several weeks
Follow-up imaging (MRI, CT scans) to monitor healing and check for signs of recurrence
Gradual reintroduction to normal activities
Regular check-ups to assess long-term recovery and neurological function
6. Possibility of Recurrence
The likelihood of recurrence depends on the type of tumor, how completely it was resected, and its malignancy grade. Benign extramedullary tumors, such as schwannomas or meningiomas, typically have a low recurrence rate after complete removal. However, malignant tumors or tumors that were not fully resected may recur, especially within the first 3 to 5 years post-surgery. Regular follow-up with MRI scans is essential to monitor for any tumor regrowth.
