Is this a PolyBeak? What happened during the healing? (photos)

Do you have a poly beak, and why? The convex appearance in profile of the lower half of your nose is what is commonly referred to as a poly beak. However the important question is whether that convexity is due to the Cartlidge below or to a buildup of scar tissue above the Cartlidge, beneath the skin. What you are experiencing is a very common phenomenon .on the operating table the surgeon often makes the tip high and the area above the tip either straight or even a little concave as your pictures are. With time however several factors come into play. First of all the tip rotates slightly downward and the projection is sometimes reduced as scar tissue forms behind the columella and contracts. The second factor is a buildup of scar tissue underneath the skin in the area just above the tip called the Supra tip. These changes are very common .if they are mostly due to a buildup of scar tissue one or more shots of Cortizone may sometimes be used to dissolve the scar tissue and correct this. If the fullness is the Cartlidge of the dorsal portion of the septum, the only way to correct this would be to reset a small amount of additional dorsal Cartlidge. This is a very common problem and one that often frustrates surgeons as well as patients.

Hi and welcome to our forum!
From your photos, the development of the deformity in the postoperative views is apparent.
The Polly beak deformity may be caused by the postsurgical gradual resettling of the underlying structural bone and cartilages (most often the septum), or excess scarring in the supratip region.
If due to excessive scarring, steroid injections may soften the tissues. Otherwise, surgical revision may be required after swelling from the previous surgery has completely abated. 15% of cosmetic procedures may require secondary touchup revision.
Revisit your plastic surgeon for evaluation and discussion.
