American Association of Neurological Surgeons - AANS 2027

The AANS Annual Scientific Meeting is described as the largest gathering of neurosurgeons in the world. Historically, the meeting has hosted more than 6,000 attendees, including roughly 2,800 medical professionals such as neurosurgeons, neurosurgical residents, neuroscience nurses, clinical specialists, physician assistants and allied health professionals. The AANS itself represents over 12,000 members worldwide. (Attendance figures vary by year; a confirmed figure specific to the 2027 meeting had not been published at the time of writing.)

The organizer had not published booth or exhibit space pricing tiers on the public meeting website at the time of writing; detailed rates are provided in the official Exhibitor Prospectus. What is confirmed regarding exhibitor badges: each 10-foot by 10-foot booth is entitled to three complimentary exhibitor badges, and additional badges may be purchased in advance for $450 each or on-site for $550 each (at the non-member, non-physician rate).

The AANS traces its origins to 1931, when it was founded as the Harvey Cushing Society; it later became the American Association of Neurological Surgeons. The organization has held an Annual Scientific Meeting nearly every year since its inception, with only two exceptions — 1945 (World War II) and 2020 (COVID-19 pandemic) — while the 2021 meeting was held exclusively virtually. Over the decades the meeting has grown into the largest gathering of neurosurgeons in the world, serving an association that today represents more than 12,000 members worldwide. Recent host cities include Boston (2025) and San Antonio (2026), with San Diego hosting in 2027 and future meetings scheduled for Washington, D.C. (2028), Houston (2029), Philadelphia (2030) and beyond.
