hi..thanks for your query
I would suggest you a few ways which i think should be able to reduce the depth of the scar on your nose.A few of theses are:
1) Subcision: a very simple OPD procedure using a needle to remodel the underlying tissues ;this helps in making the scar less noticeable.
resurfacing : Various types and methods are there ranging from the choice of a non ablative laser to ablative laser or fractional laser techniques. The choice of this would also depend on the skin type you have.
3) Fillers : These are temporary methods lasting from 1-3 years and you have to repeat it after this time period .Most popular fillers are made of hyaluronic acid
and have a vey high level of safely and give great corrections.
4) Surgical method : Exact nature of the surgery can only be given by a plastic/dermatosurgeon after seeing your scar. Skin grafting
, like the one suggested to you also gives good results if done well!
I do not know how much of an improvement in possible in your case without being able to see it , but generally a good cosmetically acceptable result in such cases is brought about by not one,but several of the methods which may be combined at appropriate intervals depending upon the depth of the scar, age of the scar and the mobility of surrounding tissues.
hope this helps, take care!
