I also had rhinoplasty when I was 16. I was awake through the entire surgery, but of course, I had been give drugs to 'relax' me. I didn't feel a thing since I was numbed up. This was many years ago and things may be different now. Brainstains (above) may have felt that she was hit by a hammer because she probably was. Many time, they have to break the mose to reset it so it will look different. The doctor also removed a hunk of cartlage. I requested that I keep it and he gave i8t to me in a bottle of preservation fluid. My mom made me throw it away after about a year.
I never asked for any particular nose; I trusted my doctor and have been happy with the results.
I wouldn't trust a cosmetic surgeon who let the patient call the shots. But the patient should be fully informed. HOWEVER, some people just don't want to know the detail. It freaks them out. I want to know everything, including where the doctor went to med school and how many of these procedures he or she has done.
Remember that, in any cosmetic surgery, the technicues depend on what kind of surgery you are getting. A rhinoplasty is completely different compared to a facelift or chin job or the removal of a scar.
If you want to see the instruments, just ask. This isn't going to be emergency surgery. The doctor should be able to show you the surgerical suite and the instruments and anything else.
Although I was a awake for the nose job, I've had other surgeries and have 'gone under.' You get wheeled into the surgical suite, already 'relaxed' from some fun drugs. The lights are bright and the doctors and nurses are all masked and ready. They put a needle in your arm and tell you when they are about to administer the drugs to put you out. They ask to to count backwards by sevens (or other task – I quoted Wordsworth since I'm lousy in math – both to see when the drug takes effect and to distract you.) It usually takes less than 10 seconds for me to go under. (The last surgery I had was last fall when they took out my appendix.)
I had a repair on a tendon in my finger and was awake for that. I asked if I could watch the operation, but the doctor wouldn't agree. He did agree to show me my finger when it was opened up. Very interesting. They put a nerve block on my entire arm, so I didn't feel a thing. I went home in a couple of hours.
