Plus moist HS-W: a new nasal packing material for the middle meatus in endoscopic sinus surgery.

Purpose: Removal of the current calcium alginate packing materials to the middle meatus in endoscopic sinus surgery (ESS) is usually accompanied by discomfort or pain owing to the hard and brittle nature of these materials. Plus moist HS-W is a new calcium alginate packing material released in 2022 developed to overcome this issue by changing the uronic acid component. We aimed to compare the discomfort/pain during the removal of Plus moist HS-W with Kaltostat, as well as their suitability as packing materials in ESS.
