The brochures listed on the left are the official brochures from the American Academy of Otolaryngology - Head and Neck Surgery. The AAO-HNS is the primary organization for Ear, Nose, and Throat Doctors in the U.S. They allows me to host these brochures, and in return, they are permitted to host my sinus anatomy series "Learn About Your Sinuses".
My medical partner, C. Ron Cannon, M.D. is the national president of this organization this year.
For general problems and information, this is a good starting point. The diagnosis and treatment pages that were written for this site provide more specific information and compliment these online brochures; they can be found in the top navigation buttons or on the right of each page. It can be helpful to read both materials to get different perspectives on your problem.
