Can i get complete rhinoplasty under only local anesthesia?

Sort of: Rhinoplaasty can be done under general anesthesia or "local anesthesia". Usually when done under local anesthesia fairly heavy IV sedation is given. In other words, it is like a general anesthetic without the breathing tube.

Local nose job?: Very difficult to do complete rhinoplasty under local anesthesia only! i recommend I.V. Sedation with local or even general endotracheal with local.

Stay safe not sorry!: In general when doing a true rhinoplasty, there is always a chance of brief but significant bleeding when septal cartilage is harvested. This is not a safety risk as far as bleeding but it can be very dangerous if the airway is not protected. For this reason most responsible surgeons prefer to have an endotracheal tube in place to protect the patient from this rare occurence.

It can be : Done, but it is much harder in the patient and surgeon. Also, more risky. Sedation, or, even better, general anesthesia with airway protection, can make the process safer, more comfortable, and more efficient.

Not suggested: It is unlikely that a complete rhinoplasty can be done under local anesthesia only. The discomfort and bleeding would not be well tolerated. A minor revision rhinoplasty can sometimes be done under local anesthesia.

Rhinoplasty w/ Local: Smaller rhinoplasties like tip work or a small dorsal hump, may be able to be completed under local, or local with sedation. Some small revisions too, but it requires a motivated and cooperative patient. Full rhinoplasty, especially requiring infracturing the nose, or work deep inside the nose is better with anesthesia. You close your eyes, and next thing you know, you are done.

You won't like it: This would be very unpleasant.
