Doherty and Cole raise important issues about our recent article in the ARCHIVES.1 These issues need further discussion, and we are grateful to have the opportunity to clarify the points they raised.

We do not agree that "because surgical outcome data are not provided," our claim is "difficult to validate." The validation of our findings comes from our careful evaluation of the results of ictal EEG recordings in these patients. We wanted to investigate whether the need for ictal EEG recordings could be obviated in this carefully selected group of patients. We believe that the correct methodological approach was to compare the final results of each of the data sets, not surgical outcome, since there are also a number of variables that influence the postoperative results, including, of course, surgical approach and technique.
