Why is my nose changing shape?

Dear katt93Thanks for the question. Rhinoplasty is used to correct malformation in the nose, including assymetry. A rhinoplasty may even be medically necessary if your nasal assymetry affects your breathing. Cheek and chin augmentation are the most effective procedures for correcting severe facial assymetry. I wish you all the best.

Hello,Asymmetric nostrils can be a result of several issues including: 
Deviated septum- a deviated central portion can contribute
Asymmetric facial structure- Almost every person’s face is asymmetric and imbalance can lead to difference in nostril appearance
Asymmetric nasal cartilage structure- Natural noses as well as those operated on can have asymmetry resulting in nostril asymmetry
Facial muscle imbalance- Some patients will have a dominant side that they smile or express on leading to imbalance.  Dynamic change (change which happens while expressing) is often a result of muscular imbalance.
Rhinoplasty can be used to make nostrils appear more symmetrical but it is almost impossible to make nostrils exactly the same.  Improvement and not perfection should be the goal.

Thanks for this question. Many factors can affect nose shape: anatomy, tissue structure, medications, infection and other issues. Seeing an experienced rhinoplasty surgeon is the first place to start. Good luck
