Cervical endoscopic spinal surgery: A review of the current literature.

Cervical endoscopic spinal surgery (CESS) is now regularly performed in some centres in the Far East, yet rarely in Europe and the United States. This review describes the application of CESS through anterior and posterior approaches with analysis of the available evidence supporting current techniques. An electronic literature search identified 52 papers and proceedings' abstracts of which 25 (16 anterior approach and 9 posterior approach) provided comparable clinical outcomes. The results revealed a good or excellent outcome from CESS in 91% (range 74-100%) with a complication rate of 5%. In a local cohort study, patients had 72% less neck pain (visual analogue scale rating) and 81% less arm pain at 6 months when CESS was used as an isolated procedure, and 74% less neck pain and 83% less arm pain when coupled with disc replacement or fusion at an adjacent level.
