Possible skin graft for overdone alarplasty? (Photos)

Judging from the pictures it might be too early to predict the outcome in this case. Once the wound completely heals and the scar fully matures the deformity might be a lot less noticeable and ameneable to less invasive modalities. I would be patient and wait for at least a couple of months before committing to another major intervention. 

First you need to let this heal and do good wound care. This is an area that heals well by what is called secondary intention- just let it heal with time. If there is significant asymmetry or irregularity of the ala after healing there are a number of ways to improve it- from composite grafts of the ear to skin resurfacing.  For now it is difficult to be patient but just let it heal.

Firstly, let me preface this by saying that the nose has the remarkable ability to heal well and scars can often remain hidden despite the dehiscence that you suffered.  Rather than continually trying to cut out scars and remove tissue, it may be better to do something to improve the quality of the scar, such as microneedling, fractionated CO2 laser, or radiofrequency.  Post current photos so that we may give you accurate counsel.
