This page provides links to pre-recorded webcasts of surgical procedures. These are actual operations performed at medical centers in the United States since January 2004. The videos last an hour. Please note that you cannot send in questions by email, though the webcast may say that you can, because you are not seeing these videos live. You will need RealPlayer to view the programs. If you do not have Real Player, you will be prompted to obtain a free download of the software before you view the presentation. You can download the RealPlayer media player at www.real.com. The videos open in a second window. If you have a pop-up blocker, you will need to disable it to view the programs.
