Abstract: [Objective] To introduce the surgical technique and preliminary clinical results of the Key hole procedure under UBE for the treatment of paracentral cervical disc herniation. [Method] One patient with central cervical disc herniation underwent the above treatment. Determine the surgical approach and working channel position based on preoperative imaging. Place the working channel on the upper and lower sides of the lower edge of the right cervical 5 vertebral plate, place an endoscope in the lower channel, place surgical instruments in the upper channel, thin the marginal vertebral plate, remove some soft tissue and ligamentum flavum, fully expose the responsible nerve root, peel off the adhesive tissue, and use nucleus pulposus forceps to remove the protruding nucleus pulposus tissue. [Result] The patient successfully completed the surgery, with significant relief in postoperative symptoms. They were able to move out of bed the next day, and were followed up for 1 year. No long-term surgical complications or symptom recurrence were found. [Conclusion] Key hole technology under UBE can significantly improve the clinical symptoms of patients with central cervical disc herniation while achieving minimally invasive goals.
