An apparatus comprises an absorbent body, a non-permeable feature, and a port feature. The absorbent body comprises a wicking feature. The non-permeable feature is coupled with the absorbent body. The non-permeable feature and at least a portion of the absorbent body are configured to fit in an opening in a paranasal sinus wall. The port feature extends through the absorbent body. The port feature defines a lumen. The wicking feature extends outwardly relative to the port lumen. During installation of the apparatus, the non-permeable feature is positioned in an opening in the paranasal sinus wall. The absorbent body is oriented such that the wicking feature is in contact with mucosal tissue in a sinus cavity defined by the paranasal sinus wall. A proximal portion of the absorbent body is positioned outside the paranasal sinus wall. |
