Summary
Biportal endoscopic spine surgery (BESS) offers a novel posterior approach for cervical disk herniation (CDH). This minimally invasive technique demonstrated significant improvements in pain and function for patients.
Area of Science:
- Neurosurgery
- Minimally Invasive Spine Surgery
Background:
- Cervical disk herniation (CDH) treatment often involves open surgery.
- Biportal endoscopic spine surgery (BESS) for CDH is infrequently reported.
- A novel posterior approach for BESS in CDH requires evaluation.
Purpose of the Study:
- To describe a new posterior approach using BESS for CDH.
- To report preliminary clinical outcomes and complications of this technique.
Main Methods:
- Retrospective chart review of 109 consecutive patients with single-level CDH.
- BESS involved creating unilateral paravertebral portals for decompression.
- Clinical outcomes (VAS, NDI, Macnab criteria, motor function) assessed postoperatively.
Main Results:
- Significant improvements in Visual Analog Scale (VAS) and Neck Disability Index (NDI) at 24 weeks (P < .01).
- Excellent, good, or fair results reported by 55.9%, 30.3%, and 13.8% of patients, respectively (Macnab criteria).
- Significant improvement in upper extremity motor function at 24 weeks (P = .02).
Conclusions:
- The posterior approach of BESS is an efficient and feasible minimally invasive treatment for CDH.
- This technique allows effective decompression with minimal bone removal.
- Further studies are warranted to confirm long-term efficacy and safety.
