A method of remodeling the uncinate process associated with a paranasal sinus includes positioning at least one shim member in the infundibulum, the shim member deforming the uncinate process and widening at least a portion of the infundibulum. The infundibulum space may be dilated with a dilating member. Dilation may occur prior to delivery of the at least one shim. The dilation member may be delivered into the sinus cavity via an access passageway formed in the canine fossa.

The invention provides a prosthetic system for treating the nasosinusitis or allergic rhinitis. The prosthetic system is provided with a wall surface which is formed by a degradable polymer and extends along the circumferential direction; the wall surface is provided with a plurality of gaps; and degradable fiber tows containing medicines are penetrated and inserted into the gaps. The prosthetic system formed by the degradable polymer can provide enough normal force vertical to the outer surface when being compressed, and after the planted part (the diseased part or the paranasal sinus opening) is released, an opened channel can be maintained with less closing possibility; and the prosthetic system is provided with a hole with the axially-hollow interior, so that after the prosthetic system is planted, the nasal cavity maintains a natural ventilating state. The prosthetic system can be naturally degraded in the nasal cavity, the degradable fiber tows containing the medicines, which are hung on the prosthetic system, can contact the diseased part which can not be directly contacted by a bracket, so that the treating effect is optimized.
