It is good to give your initial procedure time to heal and settle, usually about six months. Beyond that,the question of timing for revision is in your instance purely a matter for you to decide. You have gotten a reasonable result that will likely be significantly improved by revision. Timing of the surgery relates to your convenience and schedule as well as the degree to which your present result is bothering you. I don't believe that is any problem in waiting until April. You should do well in either instance.
Thank you for sending along your photos. I agree that the problem is much more likely to be genetic than age related. You would do well with a short scar minilift and some under chin liposuction with neck suspension. The purpose of the surgery is to leave you looking younger and refreshed, NOT looking like you have been operated on. You do not need and aggressive facial procedure that will change your overall look.David N. White, M.D.Cosmetic Surgery
It isn't unusual for neck skin to be saggy after liposuction. Over time, skin tone decreases and when fat is removed from beneath the skin the skin fails to contract adequately, leaving sags and skin excess. A skin tightening procedure can improve this look. Routinely is this would be done with a modified neck lift and muscle tightening.
It is natural to have concern when you look at your operated nose and think that something is wrong. Among the many procedures done by cosmetic surgeons, however, rhinoplasty is notable in that it takes so long to see your final result. 9 weeks is still early. The nose holds swelling and remodels after surgery over a period of many months. Typically I wouldn't consider a revision for 9 to 12 months after surgery. Left alone, contours often settle to the intended result. Should you get another opinion? I would wait and keep faith in your surgeon. There is nothing that another surgeon should do in the short run but reassure you that it is too early to tell the final result. If after several months your concerns remain, discuss them with your surgeon. Ultimately you have the option of seeking another opinion, but better to wait for your nose to more fully heal.
If you are in the immediate post operative period, some level of pain and stiffness as well as transient numbness is not unusual. Increasing pain, redness and swelling may indicate an infection and require implant removal. Persistent pain long after the procedure is unusual and deserves attention from your surgeon.
