Should I have 4 bicuspids extracted for orthodontic treatment?

I'm a 22 year-old orthodontic patient with an anterior open bite. I've had a palatal expander and mini plates that are going to be removed soon that have helped close my bite by molar intrusion. At this point I'm supposed to schedule a consult to have 4 bicuspid extractions to avoid jaw surgery, but I am hesitant about the facial effects of so many extractions. My face is already narrow and flat and I don't want that to worsen as a result.
