• Cervical posterior foraminotomy is one of the Cervical posterior foraminotomy is one of the standard methods that can be performed under standard methods that can be performed under direct (naked eye), microscopic, or endoscopic direct (naked eye), microscopic, or endoscopic visualization.visualization.
• The purpose of this study is to compare the The purpose of this study is to compare the usefulness of posterior foraminotomy performed usefulness of posterior foraminotomy performed under these 3 waysunder these 3 ways..

•Osteophytes anterior to the nerve root were not removed.Osteophytes anterior to the nerve root were not removed.•Disc hernia was removed as much as possible.Disc hernia was removed as much as possible.
• Neurological recovery and % of facet joint preservation Neurological recovery and % of facet joint preservation were not significantly different among 3 groups. were not significantly different among 3 groups.
• With naked eyes, blood loss was significantly more due to With naked eyes, blood loss was significantly more due to macroscopic visualization. macroscopic visualization.
• Postoperative CRP, time of analgesic usage and hospital Postoperative CRP, time of analgesic usage and hospital stay were significantly less with endoscope.stay were significantly less with endoscope.
• Therefore endoscopic foraminotomy is as safe and Therefore endoscopic foraminotomy is as safe and effective as microscopic foraminotomy and even less effective as microscopic foraminotomy and even less invasive. invasive.
• Endoscopic foraminotomy would be preferable alternative Endoscopic foraminotomy would be preferable alternative to microscopic foraminotomy.to microscopic foraminotomy.
