Abstract
Microdiscectomy (MD) is accepted nowadays as the operative method of choice for lumbar disc herniation, but it is not rare for neurosurgeons to opt for standard discectomy (SD), which does not entail the use of operating microscope. In our study, differences in disc herniation recurrence and clinical outcome of surgical treatment of lumbar disc herniation with and without the use of operating microscope were assessed. Our study included 167 patients undergoing lumbar disc surgery during a three-year period (SD, n=111 and MD, n=56). Clinical outcome assessments were recorded by patients via questionnaire forms filled out by patients at three time points. Operation duration, length of hospital stay and revision surgeries were also recorded. According to study results, after one-year follow up there was no statistically significant difference between the SD and MD groups in functional outcome. However, we recorded a statistically significant difference in leg pain reduction in favor of the MD group. According to the frequency of reoperations with the mean follow up period of 33.4 months, there was a statistically significant difference in favor of the MD group (SD 6.3% vs. MD 3.2%). There appears to be no particular advantage of either technique in terms of functional outcome since both result in good overall outcome. However, we choose MD over SD because it includes significantly lower recurrent disc herniation rate and higher reduction of leg pain.
