Septoplasty or rhinoplasty: which operation do you need?
The two words name two operations on two different parts of the nose, and they are not alternatives in the way the comparison suggests: they are often done together, in one anaesthetic, on the same list. What separates them for the person deciding is not the technique. It is that one of them has been tested against not operating at all and the other has not, that one is funded on written criteria and the other usually is not, and that the word printed on the consent form decides whether you have agreed to your appearance changing.
