A novel endoscopic technique simplifies thoracic discectomy using a 70-degree angled lens for direct visualization of the ventral spinal cord dura. This minimally invasive approach improves surgical outcomes for thoracic disc herniations.

Area of Science:

  • Neurosurgery
  • Minimally Invasive Spine Surgery
  • Spinal Endoscopy

Background:

  • Thoracic discectomy traditionally involves open procedures with significant invasiveness.
  • Direct visualization of the ventral spinal cord dura during thoracic discectomy is challenging.
  • Minimally invasive techniques aim to reduce surgical trauma and improve patient recovery.

Purpose of the Study:

  • To describe a novel technique for thoracic discectomy using a 70-degree angled lens endoscope.
  • To evaluate the feasibility and efficacy of direct endoscopic visualization for ventral spinal cord decompression.
  • To present surgical outcomes in patients undergoing this minimally invasive procedure.

Main Methods:

  • A 70-degree angled lens endoscope was used for direct visualization of the ventral spinal cord dura.

  • A transpedicular approach with a tubular retractor was employed for minimally invasive access.
  • High-speed drilling removed the facet joint and pedicle for disc access.
  • Endoscopic visualization guided the removal of herniated discs and bone spurs using specialized curettes.

    • Main Results:

    • The technique allowed for direct visualization of the ventral spinal cord dura mater.
    • Herniated discs and anteriorly compressing bone spurs were successfully removed.
    • Patients with myelopathy required overnight hospitalization, while those with radiculopathy were discharged same-day.
    • Two illustrative cases demonstrated the successful application of the surgical technique.

    Conclusions:

    • This endoscopic-assisted thoracic discectomy provides a simple, less invasive alternative to traditional open surgery.
    • Direct visualization with a 70-degree angled lens endoscope enhances safety and precision in ventral spinal cord decompression.
    • The transpedicular approach combined with endoscopy offers promising results for thoracic disc herniation treatment.
