Small Sides Bumps 3 Months After Open Rhinoplasty? (photo)

Three months after rhinoplasty is too soon.  You need to wait 6-12pmths before doing anything. 

Agreed, your result could have been better, and your surgeon was conservative, but how to improve?  In my opinion, the entire nasal dorsum is slightly overprojected in the post-operative result, except for the tip.  Your result would be enhanced by lowering the top of the nose more (not just the "bump"), and projecting a cute feminine tip slightly beyond the dorsum with a graft, a columellar strut, medialization of lower lateral cartilages, or by another technique. Also, would raise the tip very slightly.   In general, I find that patients ask in consultation for their "bump" to be removed, but what they really want is much more:  a beautiful nose that creates a captivating face.  Your result will continue to change after 3months, but not the relationship between tip and dorsum.

The bumps you are concerned about correspond to the edges of the nasal bones.  The Alloderm graft was most likely utilized at the top of your dorsum (radix area) to make it higher.  The dorsal bumps are very slight, at least based on your photos, and there is a chance that they may improve some more with more time.  I would suggest not to be aggressive and give it more time before you decide if you need further surgery there.
