Two week after my operation and I can confirm it has been a somewhat success. It is too early to say it was a complete success, as only time will tell once the healing is complete and the scaring has finished forming.
The procedure was to cut away all the scaring in my nose to make the airways wider, reposition my septum and repair the large hole in it. Not all could be done as the surgeon told me due to all the operations I have had on my nose and face, there was very little to work with, therefore she was unable to reposition my septum, most of the scaring was removed, but in parts it was left as the tissue was too thin. The good news was the hole was repaired, but again due to swelling etc., only time will tell if it worked fully. I have another appointment in February to see how it all is, and if I need a further more aggressive operation.
For me, being able to breathe through my nose is great and no more whistling through it.
