A self-expanding stent for use in maintaining patency of the frontal sinus drainage pathway and for the management of the frontal sinus postoperatively. The self-expanding frontal sinus stent helps maintain the pathway connecting the frontal sinus cavity open by filling this space and preventing restenosis of the frontal sinus drainage pathway following sinus surgery. The self-expanding stent may include a medical grade, flexible plastic material having with one or more recoil mechanisms having a memory to self expand. The self-expanding stent is compliant meaning that it may expand to the actual size of the space into which it is placed. The self-expanding stent may also be self-retaining. An insertion tool having the appropriate angulation and malleability may be used for ease of insertion of the self-expanding stent endoscopically into the frontal sinus. The use of a self-expanding frontal sinus stent and insertion tool for ease of insertion leads to less trauma for the patient and better surgical outcomes.
