I had read in medical papers that there is a risk of the alar batten graft migrating from it's point of support and falling into the piriform aperture, making breathing worse than it was before the operation, I understand this graft generally isn't sutured to the neighboring cartilage when applied endonasally, so is just resting there. How long do you have to worry about disrupting this graft? How long until it takes to the neighboring tissue?
