What types of treatments would help facial asymmetry due to TMJ disorder? (photos)

I have TMJ disorder which is being treated successfully with an anterior placement splint. Over the last five years I have noticed a lot of asymmetry in my face, particularly my nose which droops on one side and the nostrils are noticeably different sizes. The anterior placement device has helped a lot with the assymetry but I still feel it is very noticeable. What procedures or treatments would help me to regain facial symmetry?
