The 2015 Combined Otolaryngology Spring Meetings (COSM) is a joint meeting of seven otolaryngological societies. The meeting will feature dozens of scientific presentations highlighting research in progress in otolaryngology. Each participating society presents its own highly educational scientific program to the more than 1,200 otolaryngologists and otolaryngology residents who typically attend the meeting. The COSM program includes guest lectures by prominent leaders in surgery, numerous courses and scientific sessions, dozens of papers reflecting research related to current issues in the diagnosis, evaluation, and treatment of otolaryngology-related conditions, and two scientific poster receptions, featuring more than 500 posters. A variety of companies will display products and services that provide solutions for managing diseases and disorders of the ear, nose, throat, and related structures of the head and neck.
