Will palatal expander work in my case? (photos)

Im 20 and would like to know if an expander will work in my case and if so which type. I have mild crowding and impacted lower wisdom teeth. I also have my both upper and lower left arches inward's which this causes my left facial side to look"sunken in". My ortho suggested that we should remove 2 upper molars and the impacted wisdom. I think that making room for them and developing the arches is better for facial aesthetics . What would you docs suggest? I provided an x-ray, thanks.
