I have used the Simplicity sinus dilators since they first became available. They are my first choice instruments, particularly for in office sinus dilation procedures. I can describe them as effective, safe, and a valuable investment. Their use is intuitive and comparable to using a sinus seeker. The best way I could describe the instruments, is to have a sinus seeker combined with a dilator as a single tool. They are a game changer and I can’t imagine using anything else.
