Summary: Purpose: To examine the effects of temporal lobectomy (TL), particularly concerning its lateralization. Methods: Patients completed autobiographical memory tests, preoperatively and 1‐year postoperatively. Results: (a) right TL (RTL) patients recalled significantly more memories from the year after surgery than from the year before TL; (b) their pre to postoperative improvement on autobiographical memory scores was positively correlated to improvement of delayed story recall scores; and (c) 1 year after surgery, performance on recent personal memory recall was normalized for RTL patients only. Conclusion: We suggest that, in the absence of recurrent seizures, the relative integrity of the left hemisphere together with residual right hemisphere structures sustains postoperative autobiographical memory consolidation, at least 1 year postoperatively.
