In cervical spine surgery, it is essential to use the magnification, however, the surgical operating microscope can be expensive, cumbersome, and difficult to set up. Whereas the use of no magnification may lead to failure in removing the disc completely with no improvement of the patient condition. VITOM is an exoscope, which is used in place of operation microscope. It is easy to use and it gives same size magnification as operation microscope. This is a prospective cohort study form July 2013 to February 2014 at Helen Joseph Hospital. This study aims to evaluate the efficacy of video telescope operating microscope (VITOM) as an alternative to operative microscope (OM) in cervical spinal surgery.Patients and Methods   Patients undergoing spinal surgery were enrolled in a prospective cohort study between July 2013 to February 2014 at Helen Joseph Hospital. The age, sex, and operation-matched patients undergoing surgery using the standard OM served as the control group. During surgery, the VITOM system was used in place of the OM in 20 patients. Operative time, length of postoperative hospital stay, and intraoperative complications were assessed.Results   A total of 10 patients were studied in two equal cohorts of 10 patients each. Within each cohort, patients underwent single-level and two-level cervical spine surgery. There were no significant differences in age or sex between cohorts. There were no statistically significant differences in mean operative room time for single-level decompressions and two-level decompressions. Postoperative length of hospital stay averaged 4 days for the VITOM group versus 5 days for the traditional OM group. Subjectively, surgeon opinion was the quality of image was much higher as compared with operating microscope.Conclusion   The VITOM system provides as good a result as compared with operating microscope. However, there was no statically difference in the duration of patient stay in hospital and length of operation and interoperative complications. However, VITOM provide good visualization and better picture quality because of the high-resolution image. It is convenient also for teaching the purpose as well.
