Abstract
A method of performing sinus surgery utilizes a sinus debrider instrument having an outer tubular member, an inner member rotatably disposed within the outer member and carrying a tissue cutting surface at a distal end thereof, a suction passage through the instrument for removing cut tissue from a sinus and an annular space between the inner and outer members forming a fluid passage for supplying fluid to the tissue cutting surface. The method includes the steps of positioning the distal end of the instrument at an operative site within the sinus, cutting tissue at the operative site within the sinus by rotating the tissue cutting surface, removing the cut tissue from the sinus through the suction passage and supplying fluid to the tissue cutting surface through the fluid passage to facilitate the removal of cut tissue without introducing fluid to the operative site.
