AAO-HNS OTO EXPO (12,000+ attendees, $40/sqft standard, $44/sqft island) is the flagship ENT conference. COSM (Combined Otolaryngology Spring Meetings) co-locates multiple subspecialty societies at one venue, offering a unique multi-audience opportunity with tiered pricing from $4,100 to $16,750. ARS (rhinology) co-locates with AAO-HNS. AHNS (head and neck surgery) runs quadrennially, making its 2026 edition particularly significant. For companies selling sinus instruments, hearing devices, or surgical navigation, AAO-HNS is the primary show. COSM is the efficient play for companies that serve multiple ENT subspecialties.
