For sinuses, I'd use a combo of plasma and remote, but if you don't have plasma then run relevant programs on remote long-term. Generally speaking, we've found remote highly effective, but it's rarely a quick fix ... it takes persistence ... it's a marathon, not a sprint. Another option would be to combine contact with remote.
You could also try the cold laser. John White talks about the relevant one at 0:50 of this video.
