Our Take
Why Exhibit
Seven ENT subspecialty societies under one roof -- the only spring meeting where you can reach rhinologists, otologists, laryngologists, and facial plastic surgeons simultaneously. The tiered pricing model (Silver to Diamond) lets first-timers start at $4,100 and scale up.
Why Skip
If you only need rhinology or otology buyers, this meeting dilutes your audience across 7 subspecialties. AAO-HNS OTO EXPO in the fall is 2x the size and more commercially oriented. COSM's value is academic breadth, not buyer density.
