<s>[INST] Hello doctor, I have a hypertrophic scar on the left side of my face due to a road traffic accident from five years ago. I had undergone a scar revision surgery four years back but, no improvement was seen. So, I had a Z-plasty surgery two years back with a 40 % improvement. But, it is still visible and I am very conscious about it. Can this be improved further? [/INST] Hello. For more information consult a plastic surgeon online --> </s>
