It looks like residual retroseptal fat has remained and a revision to remove additional fat would be beneficial. As far as when to proceed, swelling has to be fully resolved. It varies from patient to patient but eight weeks should be fine on average. Best wishes, Dr. T.
At your age, lasers (clear and brilliant, Fraxel), radiofrequency (sublative, viva) or even co2 resurfacing (which would give you a quicker result) will give great results without the need for surgery. Fillers can also help this area. Please see an expert. Best, Dr. Emer.
