Is it Possible to Reshape my head at one side?

My right side of the head is much bigger than the left one. Its so much more bulky and it makes me look so rude even when I am having a neutral face. It makes me look the right side of my whole face look so much bulkier. Is there any possible way to reshape that part of head by any extent ? There is some bulky bones there compared to the left side.. Couldn't upload any photos atm.. Sorry about that. Thanks for the help..
