Trends of anterior temporal lobectomies as compared to excision of epileptic foci show no significant change over time from 2000 to Upper panel: number of cases from the Medicare Part B database for anterior temporal lobectomies (dark blue; CPT codes and 61538) compared to the number of craniotomies for excision of epileptic foci (light blue; CPT codes and 61536). Counts include both cases with ECoG and without ECoG. The year 2013 does not include data for CPT code 61534, excision of epileptic foci without ECoG, so this time point was not included in the graph. There were no significant trends in either procedure over time (F=2.59, p=0.13 for temporal lobectomies; F=3.38, p=0.09 for extratemporal resections). Lower panel: percentage of craniotomies for epileptic foci compared to anterior temporal lobectomies. There is no significant trend over time (F=4.751, p=0.052).
