Possible Nasal Valve Collapse and Breathing Difficulties After Rhinoplasty/septoplasty/osteotomy? (photo)

It Appears that you do have depression in the valve area which can be corrected with cartilage grafts to that area. However it is too soon to say since it takes 6-12 months for the swelling to go down. 

There can be internal nasal swelling at this stage still contributing to nasal blockage, but I do see the area on the left where there is some narrowing.

Your nose will continue to heal and hopefully as the internal swelling improves your breathing will also improve. If you have persistent problems you may benefit from a spreader graft to open up that narrowed area.

You can read more about spreader grafts at my web reference link below.

Sorry to hear about your breathing difficulties after your nasal surgery. Based on your description and photos it does appear that the contour depression on the left side of your nose is contributing to your poor nasal airflow. This deformity can be improved. But, unfortunately it involves another surgery. A spreader cartilage graft in the area can help with the airflow, as well as improve the appearance of your "dent." Thank you for sharing your photos and concerns. Best wishes.
