Background
Polly beak deformity is a complication of rhinoplasty defined by the typical appearance of a dorsal nasal convexity resembling a parrot’s beak.
This dosal hump is located in the supratip region of the nose which then “pushes” the tip downward causing under-rotation. It can occur through several mechanisms. If during the intraoperative evaluation of the nose, a surgeon does not recognize the improper tip-supratip relationship that is the hallmark of this deformity, a polly beak occurs. In addition, polly beak deformity may develop because of the inability of a surgeon to precisely predict the ultimate healing of the nose.

In patients, especially those with a thick skin soft tissue envelope, excess scar tissue can form in the supratip. This will produce a similar effect.
