Will Botox be able to reduce the width of my head? It's definitely the temporalis muscle that is causing this... (photo)

I've been told botox to my temporal muscle will reduce the muscle. If i pull the skin up tight above my head the shape goes normal so it's definitely the muscle that is causing the issue not the skull. I then need to have earfold treatment to correct my ears. After years of bullying and teasing even still now as an adult i think about it a lot and i've no confidence because of it. I can't find anyone in the UK who does the botox treatment. Please can someone help me...
