Can this rhinoplasty be reversed?

Your surgeon is talented, and I really like your cute, feminine, natural appearing result much better than your before.  My recommendation would be to not touch it for a while.  You will collect dividends on your beauty for many years to come.

Very difficult to reverse!~ Best to allow 6 months to allow better healing. The result appears very good but you need to be happy with the whole experience... 

An over narrow nose can be widened with spreader grafts.  An upturned nose can be turned back down with septal extender grafts.  However, you cannot "return" to your old nose, you can only take the result you have now and attempt to change it again.As your result would seem to be moderately acceptable, I think it would be very important to do imaging with your surgeon to get a good idea of what you are trying to achieve with a revision.

Although your after results show an acceptable surgical results, it appears that your new nose is very different from your original nose. It does not matter how good the result may be surgically if its not appropriate for your face, or the results were too different from what you expected.In the hands of an experienced surgeon, a revision rhinoplasty can deliver results closer to what your original nose used to look like.Best of luck,

Your after photos show a nice result.  I understand this is not what you were looking for, and perhaps you and your surgeon had not communicated the plan together very well.  I wonder if you had any morphing done in your surgeon's office prior to surgery?  I find this is a great way to discover a patient's real desires, and to avoid surgical changes that are not wanted.  It is also a way to discover unrealistic expectations of the patient, or to explain what is generally considered unaesthetic about a patient's nose (not always what they think!).  Revision surgery can be done, but when involves procedures like reverse osteotomies is more complex and unpredictable.
