Rhinoplasty to Remove Dorsal Hump and Reduce Size of Septum / Nostrils

About 14 months ago I had rhinoplasty on my nose to reduce the length of my septum, remove my dorsal hump, and reduce the size of my nostrils (which were extremely large).

I am much happier with me nose for the most part, however the size of my nostrils still concern me and I am now considering having revision surgery on them to make them smaller.

My surgeon has explained to me that there may be a risk of scarring by having the nostrils reduced further, could any of you share your experiences in nostril scarring - how likely is it, how visible are the scars, will they fade or is there any after-care treatments I can take to fade the scars, and does the fact that I have waited 14 months since my last operation improve my chances of not having scarring. As you can appreciate, this is a big decision for me (especially so, given that I am a male and rhinoplasty is not particularly masculine!), so any advice you can offer will be greatly appreciated.
