2018 AANS Annual Scientific Meeting

The educational program for the 2018 American Association of Neurological Surgeons (AANS) Annual Scientific Meeting will include the presentation of scientific data in general and subspecialty section sessions as Oral Presentations, Rapid-fire Oral Presentations and E-posters. Abstracts submitted for the 2018 AANS Annual Scientific Meeting are peer-reviewed and scored on scientific merit, originality and the relevancy to the field of neurosurgery. Although scientific data is important, the quality of the abstract is the primary determinant for acceptance by the AANS Scientific Program Committee.

Registration/Attendance Requirement

The presenting author of an Oral Presentation, Rapid-fire Oral Presentation or an E-poster must register to attend the 2018 AANS Annual Scientific Meeting by Wednesday, March 13, 2018.
