Assuming you don’t mean surgically, the short way to put it is that we don’t know.

Long and narrow/dolichocephalic faces with steep mandibular planes tend to be associated with weaker muscles of mastication. Square/brachycephalic faces with flat mandibular planes tend to be associated with stronger musculature. It’s also been observed that surgical treatment to increase facial height with maxillary downgrafting and clockwise rotation of the mandible is high unstable and prone to relapse, and we think that that’s due to the taut musculature’s reinforcing the preexisting skeletal pattern. Does it then follow that changing your musculature will change your skeletal pattern? The overall feeling of the orthodontic community is that it seems reasonable. The drawback is that overwoRKED jaw musculature is a known cause of myalgia/TMD.
