Post Rhino Breathing issues / collapse (Photo)

On your photos, the right side does appear to be going inward a bit. This would have to be evaluated with a full set of photos and exam, but it the nasal valve is narrowed, this can be improved with a revision rhinoplasty. Cartilage grafting can be placed properly to accomplish the result while keeping the nose looking good. Be sure to see a rhinoplasty expert for consultation.

The maneuver you are doing is called the Cottle maneuver. It opens the internal nasal valve passageway, which is composed of the upper lateral cartilage, septum, and inferior turbinate. Any disharmony between these structures may cause internal nasal valve narrowing and therefore airway obstruction due to decreased air flow. I would recommend getting a second opinion and an intranasal examination with a reputable American Board of Plastic Surgery certified surgeon.

Hello! Thank you for your question
As far as I can understand from your question
You should have a detailed examination, the inside of the nose needs to be checked and a path can be followed accordingly.
Best Regards!

When somebody's breathing is significantly improved by pulling the cheek away from the nasal septum, that tends to mean that there is a narrowing of the external nasal valve. Generally, something like that may be repaired with a lateral crural strut graft to support the airway. Since that would necessitate revision rhinoplasty, and since the slight asymmetry at the base view of your nose is not perceptible to most, if you could live with this, that would be the best. If you can't, consider meeting with several reputable rhinoplasty specialist so you can see what to expect moving forward.

Your symptoms are highly suggestive of nasal valve collapse. I would suspect the internal nasal valve given where you are pulling on your cheek for results and the fact that your nostril itself does not appear to be collapsed.

Internal nasal valve weakness/collapse is very common after reduction rhinoplasty if maneuvers aren't performed to decrease that possibility.

A revision may be warranted given the failure to improve with medical intervention.

Persistent breathing issues and nostril collapse 1.5 years post-rhinoplasty likely stem from nasal valve dysfunction or structural issues. Manual relief by pulling the cheek suggests weakened cartilage or narrowing. Consult a specialist to explore treatments like cartilage grafts or revision surgery.
