Undefined Bridge 11 Months After Rhinoplasty, Will This Change?

Photos would really be necessary top give you advice on the issue you are experiencing. It is possible you may still be experiencing some residual swelling even after 11 months. In general, the final result of rhinoplasty is not evident for 18-24 months following surgery. 70% of the swelling is resolved after the first 3 months, and the remainder goes down over time. Swelling can be influenced by the following: thickness of the patient's skin, whether the procedure was a revision, whether tip work was performed, and whether the procedure was open or closed. The nose continues to change throughout the healing process, and you should see improvements over time. If you are still not happy when the final result of your nose is evident, it is possible to perform a touch up to improve the appearance of your nose. I hope this helps, and I wish you the best of luck.

Generally, after 11 months, you are very close to your final result.  This is especially true in the bridge (usually final by 3 months).  It sounds like you had the bridge lowered too much (over-resection).  This can be fixed with a bridge augmentation using an implant or cartilage (I usually recommend cartilage).  This would require a revision surgery but the recovery is typically much easier than surgery that involves the tip.

Your bridge will not change without revision rhinoplasty. I need to see photos to give you a proper answer.
