surgery on the ethmoid (eye area) sinuses

surgery on the maxillary (cheek) sinuses

You mean sphenoidectomies
surgery on the sphenoid (deep in the head sinuses)

surgery on the frontail (forehead sinuses)

There's no reason not to do them all at one time if they all need to be done.

It is a lot of surgery tough.

The main issue is always the skill and eexerince of the surgeon, not
necessarily which surgery is done.

May be 2 to 3 weeks unless you're a superman.

If possible I would recommend getting a 2nd opinion.  I wish that i had
done so before getting my first surgery which if I remember correctly
sounded quite a bit like yours above.  subsequent ENTs that i have gone
to, one of which did a follow up surgery to the first, told me that this
surgeon was "old school" and he had done sone damage including putting a
fairly sizable hole in my septum--(i know that he did this because he
never mentioned it, not before or after the surgery and it is the first
thing that any subsequent ENT has ever commented on).  You wouldnt have
guessed that the first surgeon was the less able by his manner or,
especially, by his office location, but his was an assembly line
operation, and from what i gathered since, his recommendation is always
surgery.  the healing process from the first surgery was long and
uncomfortable, especially the first 48 hours when i had about 2 feet of
gauze jam-packed up each nostril.  on the 2nd day after the surgery i
showed up at the drs office where he had me sit by a sink and told me that
after he removed the gauze i would need to hold my nose tight and spit out
the blood into the sink.  he then ripped the gauze out and it was one of
the most painful experience that i had ever gone through--it may have been
that this was when the septum got ripped.  in contrast, following my 2nd
surgery (admittedly not as intense) i had no packing and very little
discomfort.  

perhaps some surgeons on this site can answer:  do some surgeons remove
more than others?  i believe that my second surgeon said he would have
opted to open the sinuses up to encourage drainage rather than scrape it
out.  
                                         

I wish I could help you, but I never had all 4 done simultaneously.  I
had the ethmoidectomies and the maxillary antrostomies as well as the
septoplasty.

From my experience, by far the most amount of post-operative pain came
from the septoplasty.  The bridge of my nose hurt a lot.  My ENT gave me
Percocet for the pain.  I had very little or no pain from any of the
other procedures.

If you think you might have a low threshold of pain, ask your ENT to
give you a prescription for Percocet, which you can take to help you sleep.
