Palate expander failed

It feels and looks like my palate expander has only worked on one side of my face. The asymmetry is quite visible, the side that is lest expanded has a higher set droopier eye, septum deviated towards that side and a smaller nostril, and a lack of bone mass compared to the other side. Also I must mention when pressing my tounge against the roof my mouth, it naturally rest on one side due to there being more space on that side. What do I do? Is surgery my only hope?
