Background: Significant variability in quality of operative videos presents a challenge for those in the field. Some surgical subspecialties have developed scoring systems to address this issue and measure the quality of published videos in their respective disciplines. Thus, we examined the literature for operative videos related to skull base surgery and developed a grading scale based on previous efforts to assess them.
Methods: Four neurosurgical journals publishing standalone videos were queried for the term “skull base”: Operative Neurosurgery, Neurosurgical Focus: Video, World Neurosurgery, and Surgical Neurology International. A number of variables were collected for each including author information, number of citations, topic, and scores for established grading scales. Each video also received a “Memphis Video Score” comprised of 14 components representing 0-2 points each for a total score of 28 points. Statistical calculations were performed in Microsoft Excel.
Results: After removal of duplicates and videos not involving an operative case related to skull base, 394 results were included for analysis. 241 (61.2%) publications originated from within the United States with the Northeast (80, 33.2%) and the West (71, 29.5%) providing most of these. From outside the United States, Brazil (25, 16.3%) and Japan (13.7%) were responsible for the most videos. The most common topic was Tumor (131, 33.2%). The two institutions with the largest number of surgical videos published were Mayo Clinic (29, 7.4%) and the University of Utah (16, 4.1%). Overall, the mean number of citations per publication was 3 (0-19), and the average Memphis Video Score was a 25 (6-28). There was a significant correlation between these two variables (p = 0.049). There was also a significant difference in average scores between the journals (p < 0.001) with Operative Neurosurgery demonstrating the highest mean score (25.9).
Conclusions: The rise in popularity of operative videos within the neurosurgical literature is well established. This novel medium has facilitated the increased dissemination of information related to surgical skill and techniques, but there remain reasons to be cautious regarding their benefits. We found that the majority of skull base operative videos published within the neurosurgical literature are of high quality, but certain factors significantly correlate with the variability in their quality.
