Patients undergoing surgical intervention for epilepsy mapping are typically administered opioids for pain control. The use of opioids is demonstrably lower after other procedures when a minimally invasive surgery (MIS) technique is used. Our objective was to determine whether using MIS for stereoelectroencephalography (SEEG) resulted in lower opioid requirement by pediatric patients when compared with subdural grid placement after craniotomy (ECoG). A retrospective chart review was conducted to identify patients < 18 years who underwent epilepsy mapping surgery using SEEG or ECoG in 2015-2019. The hospital stay was divided into four time periods, and the total amounts of opioids (converted into morphine milligram equivalents (MMEs)) and nonsteroidal anti-inflammatory drugs (NSAIDs) and pain scores (on numerical rating scale (NRS)) were calculated for each time interval. The two groups were then compared statistically. The study included 31 patients in the SEEG group and 9 in the ECoG group. The SEEG group consumed significantly fewer opioids during the hospital stay than the ECoG group (23.6 vs. 61.7 MMEs; p = 0.041). There were also significant differences in the length of stay (6.9 vs. 12.2 days; p = 0.002), rate of complications (0% vs. 20%; p = 0.006), and total NSAIDs consumed (3,264.8 vs. 12,730.2 mg; p = 0.002). Opioid and NSAID consumption were significantly lower and hospital stays were shorter in pediatric patients who underwent epilepsy mapping via SEEG compared with ECoG. These results suggest that MIS for epilepsy mapping may decrease the overall pain medication use and expedite patient discharge.
