It is possible to have another revision
rhinoplasty, although it may be a good idea to wait longer, as it can take longer for the nose to completely heal after a revision rhinoplasty than for the first rhinoplasty.
However, revision rhinoplasty is one of the most challenging of all
surgeries, and each time a rhinoplasty is done, it becomes increasingly
complex. Keep in mind that there are many factors involved, so your nose
not turn out exactly the
way you want the third time either. I recommend getting a second or even
third opinion in person from a well-experienced revision rhinoplasty specialist.
This is a tough problem. I have come across it a few times. I think that the results become harder to predict the more revisions you have. Without knowing what was exactly done, it seems as though your skin at the tip is thicker than for the remainder of your nose. It might be more difficult to refine that further. You should wait two years to revise a revision nose. So maybe the tip will reduce more, but I think the difference will be small.
The thicker the skin the longer it is going to take to decide about the final outcome of the rhinoplaty, especially in the tip area. Rarely, some noses may take 3 years to reach the final outcome. So, your surgeon is correct in asking you to wait. When the time comes and if the revision becomes necessary, your surgeon may suggest to reduce the projection of your tip slightly and correct the deviation of the columella (the column between the nostrils). Additionally, in 3 out of the 4 photos your lips are open. This means to me that you may have breathing problems and you may want to discuss this with your surgeon, if my observation is correct.
Your surgeon is correct that you may still expect changes after the one year mark. However, I believe the changes you will get at this point are relatively small and may not correct the issues you are asking about. I would see if your initial surgeon would consider operating at this time, or maybe consult with another revision rhinoplasty surgeon.
Best of luck
