Objective:

To introduce the technical protocol of unilateral biportal endoscopy (UBE) in the treatment of patients with non-aggressive spinal benign tumors and evaluate its clinical efficacy and safety.

Approach:

• Study Design: A retrospective analysis was conducted on 14 patients with pathologically confirmed spinal benign tumors who underwent UBE surgery.
• Data Collection: Operative duration, total perioperative blood loss, and postoperative complications were recorded. VAS scores were compared preoperatively and at various postoperative intervals.
• Surgical Procedure: Surgeries were performed under general anesthesia using a pedicle approach, with endoscopic techniques to remove tumor tissues.

Key Findings:

Interpretation:

The study presents UBE as a surgical option for non-aggressive spinal benign tumors, achieving satisfactory lesion resection and favorable clinical outcomes.

Limitations:

• Small sample size of 14 patients.
• Retrospective study design may introduce bias.

Conclusion:

UBE is presented as a surgical option for non-aggressive spinal benign tumors.
