I would give things more time to allow swelling to completely resolve. I generally recommend waiting a year before making a final decision on a nose. Then if you are not satisfied, you can proceed with revision. Good luck. Donald R. Nunn MD Atlanta Plastic Surgeon
Silicone implant revision? It is too soon to say but generally as more swelling goes down it will look worse along the sides. Wait at least 2 months and then see your surgeon or a revision rhinoplasty surgeon. I do these with cartilage and do not use silicone for many reasons. Other surgeons like silicone.
From the photographs provided I don't see anything particularly wrong. Any specific questions you have about the appearance of your nose should be addressed to your plastic surgeon. In any event four months is too early to consider a revision.
Usually fat grafts get somewhat reabsorbed so I expect your tip to go down. You can help by massaging the tip in an upward fashion. I don`t usually use silicone implants but their infection rate is low and they do not integrate into the nasal tissue and can be easily removed if you dont want it. My advise is to wait at least a year to have the nose settled and then decide if yu want a revision. You should first go back to your plastic surgeon.
