When i had pituitary surgery, my head was secured during surgery. woke up with wound in hair. will they secure head like that for septoplasty?

Probably Not: When you had pituitary surgery, they placed your head in a so-called "halo." This is a device that has small metal bolts that hold the skull in place during surgery to prevent movement and sometimes to help with localization. This sort of contraption is not necessary for septoplasty, which is considered to be a less dangerous/risky procedure.
