How long after rhinoplasty withrib cartlidge do I need to stay at hospital ?

Many surgeons, including myself, perform rib cartilage grafts as an out-patient procedure with no hospitalization. The pain from a rib graft is no more than from an ear cartilage graft which is commonly performed as an outpatient

Every patient is diferent. Generally if my patients are local they go home the same day even with a rib graft. If they have traveled far they are given the option of a night in the hospital or a recovery facility. If you have good family support go home. 

I have never kept one overnight. It is usually done as an out patient. But this is really up to you and your surgeon.
