Yes I can give you some help about this. I am Jeremy and I'm male and
living in the UK

January 2006 I had a sudden increase in blockage to my right nostril
the clearest one of the two and a scan showed I was riddled with
Polyps as well as a having very severely deviated septum.  I've had a
bent septum since birth - I am now 61

I had to badger the ENT consultant (in the UK "National Health" free
treatment system to operate and remove the polyps and straighten the
septum.  Several people had told me the operation is a very good one.
Polyps can return depending on type.  But the septum straightening was
something I was more anxious to have done than the polyps.

Anyhow I couldn't get them to agree to do it. They had a load of
warnings about potential damage to eyes and that kind of thing which
they have to inform you about legally but it's only a one in 3000 risk
or something.  But anyway I went privately to a Surgeon outside the
NHS system and paid about $4000 2000 uk pounds to have the operation
done. It was a simple procedure and carried out one afternoon and I
stayed in overnight and was allowed home when the dressing packs were
taken out next morning.

Several weeks later, about 3 weeks I'd been douching my nostrils with
sterile seawater nasal spray 3 times a day, to keep it healing nice
and clean and then my breathing through the nose was quite remarkable.
The relief was unbelievable.  But I have to say I was hoping my
Tinnitus might be improved but it remained exactly the same.  So at
least it wasn't worse.

My tinnitus is cochlea haircell damage from noise and added to it I
have hereditory deafness crept up on me in 1993 to 1998 and now I wear
two digital hearing aids which act as tinnitus maskers just by them
putting more sound in my ears artificially and changing the signal to
noise ratio.  Hope that's all clear sorry it's a bit technical.

The bad news is that the polyps he dug out transpired to be partly a
very rare cancer called a Neuro Blastoma.  This was in the Olfactory
organ at its root and Olfactory Neuro Blastomas do eventually kill
you.  However I was referred to an expert head and neck cancer surgeon
who operated in June 2006 and he dug out 23 more biopsies of polyps
and only one small part of those was a neuro blastoma.  So I had just
gotten over that surgery when I had a massive haemorrage from the area
when a blood vessel sprung a leak.  July 2006 I was rushed into
hospital and next day a blood transfusion just saved my life and they
had to put monster packs up the nose and they were left in for three
days then removed and I was OK.   A month later I had to have 20
fractions of Radio Therapy to the nasal area which by then had been
stripped of two thirds of the septum along with some skull bone
removed to make sure they'd got at the root of the blastoma.

That final procedure wasn't very nice but I weathered it.   The major
surgery didn't change my tinnitus at all. Still stuck with it night
and day but I live with it.  I taught myself to habituate it with help
from my family and some treasures who used to be on a.s.t.

So finally I'd say if you want to have septum straightened go ahead
with it. They do a super job with it now and you really must be able
to breathe through that nostril.  I've lost 99% of my sense of smell
since the olfactory organ was all but removed.
I can still taste but it's not what it was. Small price to pay for
life.  I'm having regular MRI scans and keeping an eye on anything
returning.  No idea when or if.  A bit of a gamble but I try not to
worry about it.
