I had revision rhinoplasty 3 months ago to correct inverted V deformity with spreader grafts (from rib cartilage). My surgeon is very experienced and I'm happy with the result so far. The only problem is that I've been experiencing breathing difficulty through my right nostril lately. I feel something blocking and flapping inside especially when I lay on the right side. When I lay on my left side it opens up. Is it possible that my valve has collapsed or can it be a temporary issue?
