Parrot beak 5.5 months after rhinoplasty - Could I have developed Polly beak deformity? (photo)

It is normal to have some residual swelling following Rhinoplasty procedure which takes 3-9 months to resolve, completely. I do not think, you have any deformity.

You should wait for 6 months more till all micro edema subsides ,after that you can make judgement about results and decide if you want to have a revision Rhinoplasty

Hi and welcome to our forum!

The performance of rhinoplasty involves the separation of the nasal bones and cartilages from overlying and underlying structures, fracturing the nasal bones, removing excess bone / cartilage, reshaping of the remaining bone and cartilage. The significant intraoperative trauma causes swelling (which may be asymmetric), which will make your nose look large and wide. 60-80% of the swelling will resolve within 6 weeks, with the remainder slowly abating over 6-12 months. The nasal tip is notorious for taking the longest time. At this point one cannot discern between residual swelling and a small pollybeak.
It is recommended that you wait until swelling has totally abated before contemplating any revision. Is the tip still firm? 
I recommend you schedule reevaluation by your plastic surgeon and express your concerns.
Best wishes...
 
Continue followup with your plastic surgeon.
