Is this normal to have a foul stale odor from a perforation? Smells musty or cheesy and people comment. I previously had sinus surgery and discovered the hole post surgery. I then had a silicone button inserted and now that has been removed it wasn’t helping. I do saline rinses daily but the odor still persist. Will surgery mitigate this odor.? When I bend down or lay down it’s prominent. What are my options for a successful closure and odor remedy? Help please.
