Why do some surgeons only offer general anesthesia for rhinoplasty & what are the advantages of each method? (Photos)

Although rhinoplasty without septoplasty may be done in twilight or even local anesthesia, it is very likely that, considering size and shape of your nose, you may need a septoplasty as well. This is done not only to correct underlying septum deformity and obstruction but also as a source for septal cartilage graft which may be needed for tip support. This procedure, septorhinoplasty, is best done in general anesthesia and provides intraoperative safety and comfort for both patient and a surgeon. Hope this helps.

Because you are working in the airway it is easier and safer to do general anesthesia for more complex rhinoplasties.
