Takeaway
Temporal lobe resection (TLR) results in hippocampal volume (HV) reduction and memory loss even with complete hippocampal sparing (HCS).
Why this matters
Epilepsy surgery within the temporal lobe is associated with risk of memory decline; hippocampus-sparing resection is utilized to spare memory function.
In a previous study, the authors found memory decline in patients undergoing TLR with and without hippocampectomy.
