i have anosmia and have tried the standard treatments including antibiotics,steroids, long term nasal washes with a netty pot including Flonase. ENT doc has done the scope and sees rhinitus up in that olfactory cavity. He wants to do a sinus procedure that I cannot name which presumably scrapes that area. Any idea of the success rate of this procedure?? I m 65 but should not be that much of a factor; pretty much lost sense of smell and taste over the last year
