Rhinoplasty is often completed under a general anesthesia, though a sedation technique also works quite well for some patients. Anesthesia or sedation does require some time and preparation in its own right and though a average nasal shaping will take perhaps an hour and half, the time a patient is 'out' is approximately two hours. The time of the operation can of course vary, however after an hour and half, or so, swelling can begin to take hold and we feel it is best to have the nose set right, taped and splint in place by this time if possible. After sedation or anesthesia though, patients are 'awake' they may not remember clearly for an additional hour, but after this should feel well and be prepared for a trip back home.Best of luck,peterejohnsonmd
