Spinal and Spinal Cord Tumor Surgery

Spinal and spinal cord tumors are significant within central nervous system tumors. These tumors can be benign (non-cancerous) or malignant (cancerous), and surgical treatment plays a crucial role in their management. Spinal and spinal cord tumor surgery is a complex field requiring precision and a multidisciplinary approach.

Classification of Spinal and Spinal Cord Tumors

Spinal and spinal cord tumors can be classified based on their localization as follows:

1. Extradural Tumors: These are tumors that originate from the spinal bones or spread to this area. An example of this type is metastatic tumors.
2. Intradural-Extramedullary Tumors: These tumors are located within the spinal meninges but do not originate from the spinal cord itself. The most common tumors in this group are meningiomas and schwannomas.
3. Intramedullary Tumors: These tumors originate from the spinal cord itself. Gliomas and ependymomas are frequently seen in this group.

Indications for Surgical Treatment

Surgical treatment is planned based on factors such as tumor localization, histology, the patient’s clinical condition, and the size of the tumor. Surgical treatment is generally preferred in the following situations:

• Significant loss of neurological function
• Tumor causing spinal instability
• Pressure on the spinal cord
• Suspected malignancy of the tumor

Surgical Techniques

1. Surgery for Extradural Tumors: These tumors are typically removed through vertebrectomy or laminectomy. Spinal instrumentation is commonly used for stabilization.
2. Surgery for Intradural-Extramedullary Tumors: The goal is to completely remove the tumor using microsurgical techniques. Neuromonitoring is critical in these surgeries to preserve spinal cord function.
3. Surgery for Intramedullary Tumors: Since these tumors arise from spinal cord tissue, surgical risks are higher. Microsurgery and intraoperative neuromonitoring are standard approaches in these cases.

Postoperative Period

Close monitoring of patients is required in the postoperative period. Potential complications include:

• Neurological deficits
• Infection
• Spinal instability
• Tumor recurrence

Physical therapy and rehabilitation are critical components of the recovery process following surgery. Additionally, in cases of malignant tumors, adjuvant therapies such as radiotherapy and chemotherapy may be necessary.

Spinal and spinal cord tumor surgery is a highly specialized field requiring advanced technology and expertise, along with a multidisciplinary approach. Early diagnosis and appropriate treatment planning can enhance the quality of life by preserving neurological functions in patients.
