Nasal polyps

Question:
I am now a qualified advanced open water diver and also nitrox diver. Unfortunately, I suffered bleeding into the back of the throat from the sinus area, which happened on my previous dives and did not clear up. The ENT Doctor cleared up the problem with medication and has discovered that I have a polyp which is too deep to operate on and so he is using cortizone type medication to hopefully destroy it. This is heart-breaking for me as an enthusiastic recently qualified beginner, as I was becoming more comfortable and confident with diving. I would therefore appreciate it if you could send me information on how diving effects polyps, safe diving when there is possibility of a polyp bleeding severely and alternative equalizing methods that may help.

Answer:
Nasal polyps are not an uncommon problem, and they have normally little direct relation with diving, unless they are causing bleeding, as it is in your case, or difficulty in equalizing, as it does not seem to be the case now, fortunately.
Diving per se does not affect polyps, unless they are located in areas where they may cause obstruction of an air filled cavity or create an artificial cavity by "plugging in" in orifices or crevices within the nasal structures. The last would seem to be a possibility for the bleeding problems you suffer from.
If this is so, there would be no equalizing method that could work in that paricular area, as the plugging polyp might create a cavity with one only orifice, i.e. the one blocked by the polyp itself. The consequent congestion of the local mucosa and of the polyp itself generates the bleeding, which may only become evident, if it happens towards the artificial cavity, on ascent, when the decreasing pressure causes the re-expansion of the gas in the artificial cavity and helps "unplugging" it, thus releasing the polyp and the blood.
If this polyp is constantly generating problems on every dive, my suggestion is to wait until the therapy has an effect, and starts at least reducing the size of the polyp, making it less likely that it may swing in the nasal cavity and generate the "plugging" effects I desciberd above.
If the polyp only generates problems occasionally, when you have a cold of may have congested nasal mucosa, then the pre-dive use of nasal decongestants may help, until the problem is cured once and for all.
