Can a cartilage graft dissolve over years after a Rhinoplasty?

Hello,You should not worry about nostril collapse after a hump reduction unless there is lower lateral cartilage destabilization in aggressive tip narrowing procedures.  Internal nasal valve collapse is a real concern with large hump reduction, since this can cause the upper lateral cartilages to lose support and fall inwards. This can cause a pinching inwards in the area just above your tip area.  Cartilage grafts can resorb but it is uncommon.  They can warp depending on what part of the body is donor source.  Banked cartilage is not a source that I recommend in my practice.  I would consult with a rhinoplasty surgeon with experience and a good reputation.  Good luckDr. Chow

Not all dorsal hump reductions require spreader graft placement. However, in some cases it is required to place spreader grafts in order to prevent internal valve collapse.  Cartilage grafts harvested from nasal septum are resilient and do not easily resorb. 

It is more common for cartilage grafts two dissolve over months time rather than years time. When a graft is placed, for it to be successful little capillaries must grow into it to give it circulation. If this event does not occur, often a cartilage graft will dissolve. It is possible however for tissue to distort or partially lose its sharpness by chronic pressure from surrounding tissue.
