Hi there. Septoplasty
will straighten out the cartilage
that divides your nostrils into left and right. This should allow your sinuses
, on the side of your face your septum is bent towards, to drain more freely and get rid of a lot of the stuffiness you describe. Also, if there is a nasal polyp, that often develops with DNS, this too can be dealt with giving you further relief.
I think you misunderstood the doctor about "fainting
you". You will be given a light general anaesthetic
during which you will feel absolutely nothing nor remember anything afterwards -- as if you have fainted.
This operation may not cure you of all all that ails you But it will fix a lot of it. You have nothing to worry about. I hope you enjoy better health soon..
