Hi, I have performed and taught Rhinoplasty for 30 years. The local (Liodcaine) used to inject the soft tissues, of the nose during a Rhinoplasty, wears off in about 1 and 1/2 hours. This includes the effects of the epinephrine within the local solution that controls bleeding during the Rhinoplasty. There are ways to inject portions of the tissues to extend the Rhinoplasty to 2 hours but IMHO, that's about the limit. It tales me about 1 hour for a Closed Rhinoplasty and about 2 hours to perform an open Rhinoplasty. Revisions add some time but remain within these time limits. A 7 hour Rhinoplasty would have tremendous amounts of bleeding which equates to much more post op bruising and swelling. Meticulous pre-op planning and experience are required to keep within the strict time limits mentioned above. Theses are some of the reasons for selecting a very experienced, well trained Rhinoplasty Surgeon. Hope this helps.
