Pollybeak Appearance 2 Months after Columella Surgery
The pollybeak appearance may be secondary to post-op swelling. As you know the columella is important in maintaining good tip projection. Hopefully tip support was not compromised with the columellar revision. Discuss your concerns with your surgeon.
Pollybeak Deformity After Revision Rhinoplasty on the Columella
It seems unusual to acquire a pollybeak deformity after revision surgery on the columella alone, and probably represents a known complication of the original surgery. Cortisone injections can be very helpful if the pollybeak is due to soft tissue. Consult with your surgeon.
