How long does liquid rhinoplasty last? Several people who have had minor nose surgeries are used to compare how long it takes to heal after rhinoplasty. Most of the time, an open nose surgery takes anywhere from two to five hours. Surgery could be put off, though, if the patient’s body is trying to get rid of cartilage and there are problems with the nose. During this procedure, the nasal airways are cut in small places. This cut doesn’t usually bleed during or after surgery. After open plastic surgery, a person who is very sensitive about their nose might bleed. During the procedure, neither the surgeon nor the patient wants to lose blood. In this situation, the doctor must be very careful.
