2 months back FTSG surgery done on my nose: now it looks like dark spot, any other solution? (Photos)

Excision of the full thickness skin graft and direct closure of the defect would be the best option in my opinion. This may lift the tip of your nose slightly but will result in a better appearance. A skin graft is inevitably going to look different from the surrounding skin.

Better option to remove FTSG skin and cover with small flap from the nose, either V-Y or rotational flap. 

It is not unusual for non-Caucasian skin types to develop hyperpigmentation in the process of healing. That is why is so important to avoid sun exposure in the first few months of healing.  If this is the result of sun exposure, the darkened spot may not return.  If sun has been avoided, there is a chance for improvement over time.  I typically wait a full year before revising reconstructions unless they are disfiguring (causing emotional distress) or causing some kind of physical impairment.  I would recommend a local flap as well for better skin match.  There is still the same risk after revision for darkening of the incisions, though not the entire flap with sun exposure.

Hey there,Unfortunately, pigmentation following STSG, FTSG is quite common. Massage the grafted area well with a silicone gel-based cream twice to thrice daily for 8 weeks. Hydroquinone based skin creams may be tried but with unpredictable results. Excising and trying to cover the defect with a local flap would add to additional scarring. finally, there is no proper consensus on what modality of treatment would be appropriate for such a condition.
Hope this helps.

Full thickness skin grafts are great to cover different types of skin defects on the face, however, the skin color does not always best match the area you are reconstructing.  For the spot on your nose, the best option is to remove the area of dark skin and reconstruct it with skin directly adjacent to the area. This is called a local skin flap.  Different designs and techniques can be used to create a local skin flap.Talk to your surgeon about the best option for a local skin flap. This will be your best option to remove the dark spot on your nose.Best of luck.
