Bilateral Endoscopic Cervical Foraminotomy Shows Superior Recovery Outcomes Compared to Microscopic Surgery, Study Finds
A study published in the Journal of Clinical Medicine (JCM) reports that bilateral endoscopic cervical foraminotomy, a minimally invasive procedure, outperforms traditional microscopic surgery in reducing postoperative pain and accelerating recovery for patients with cervical radiculopathy, according to research led by Dr. Han Sang-yup at Wills Memorial Hospital.
What Is Cervical Radiculopathy and How Is It Treated?
Cervical radiculopathy, often caused by herniated discs or spinal stenosis, occurs when compressed nerves in the neck lead to pain, numbness, or weakness in the arms. Treatment options include conservative care like physical therapy or surgery. The study focused on two surgical approaches: microscopic posterior cervical foraminotomy and unilateral biportal endoscopic posterior cervical foraminotomy.
“The goal of these procedures is to relieve nerve pressure while minimizing tissue disruption,” said Dr. Han, who heads the spinal surgery department at Wills Memorial Hospital. “Our findings highlight a technique that balances efficacy with patient recovery.”
How Did the New Technique Perform Compared to Traditional Methods?
The study analyzed 73 patients treated between 2018 and 2021. Patients undergoing bilateral endoscopic surgery experienced significantly lower pain scores (visual analog scale, or VAS) immediately after surgery and at two weeks post-operation compared to those who had microscopic surgery. The endoscopic group also had shorter operative times (105 minutes vs. 130 minutes) and less blood loss (39.5 mL vs. 141.3 mL), according to the research.
“The reduced blood loss and shorter surgery duration translate to less trauma for the patient,” explained Dr. Han. “This likely contributes to faster functional recovery, which we observed in the early postoperative period.”
What Were the Long-Term Outcomes?
At three months and beyond, both groups showed comparable pain relief and functional improvement. Radiographic assessments, including spinal alignment and disc height, did not reveal significant differences between the two techniques. Neither group experienced surgical site instability, and complication rates were low in both groups.
“The long-term results suggest that both methods are viable,” said Dr. Han. “However, the endoscopic approach offers immediate benefits that may be particularly valuable for patients prioritizing quicker return to daily activities.”
Why Does This Matter for Patients and Surgeons?
The study adds to growing evidence supporting minimally invasive techniques in spinal surgery. A 2022 review in Spine noted that endoscopic procedures often reduce hospital stays and postoperative discomfort, though long-term data remains limited. This research provides additional data to guide treatment decisions.
For patients, the findings underscore the importance of discussing surgical options with their care team. For surgeons, the study highlights the need to balance immediate recovery benefits with long-term outcomes when selecting a technique.
What Are the Implications for Future Research?
While the study supports the use of bilateral endoscopic foraminotomy, larger, randomized controlled trials are needed to confirm these results. Researchers also emphasize the importance of standardizing surgical techniques to ensure consistent outcomes across institutions.
“This is a promising step forward,” said Dr. Han. “As technology evolves, we can expect further refinements that may enhance patient care even more.”
