ABSTRACT
Article history: Aim: Full-endoscopic posterior cervical foraminotomy (FPCF) has been utilized to treat
Received: 05-03-2017 cervical lateral disc herniation and provided good surgical outcomes. The authors examined
Accepted: 24-04-2017 the superiority of FPCF in patients with spondylotic foraminal stenosis. Methods: Fifty-nine
Published: 30-06-2017 cases of FPCF were evaluated. Of the 59 patients, 34 had lateral disc herniation (group H)
and 25 had spondylotic foraminal stenosis (group S). Operative time, complications, length

surgery in both groups (14). In both groups, 52% of the facet joint was resected. Conclusion:
The surgical outcome of FPCF in patients with spondylotic foraminal stenosis is equivalent to
that in patients with lateral disc herniation.
