Deviated septum, semi facelift, semi neck lift, breast lit/augmentation - should this be done all at once or separately?

I'm a 34 year old female, 5'5", with light complexion. It is medically necessary that I correct a deviated septum. I'd like to pair that with a semi face lift (with asymmetry correction) and semi neck lift, and might as well throw in a breast lift/augmentation too. Is it better to do this all at once or piece by piece? Which will ensure best results?
