I need Septoplasty for medical reasons. I am planning to combine Rhinoplasty with it. One surgeon I consulted said that he uses general anesthesia because he can ensure my breathing continues and the breathing tube ensures that blood from my nose does not get into my lungs.
The other surgeon said that he uses IV Sedation (Twilight sedation) because it is sufficient and because recovery is easy. The anesthesia-nurse said an air-mask prevents blood from entering my lungs. Both said that the anesthetic is administered through an IV. So what's different between the two methods? The drug? The dosage?
