We are all to varying degrees asymmetric. It's usually a bad idea to chase perfection as you will always be disappointed. It may help to have Botox or fillers to reduce the asymmetry but you need an in person consultation with someone very qualified to help answer that question.
Without pictures or an exam, it is impossible to give you sound advice. My office is in NJ and would be happy to see you in consultation.
I specialize in rhinoplasty.
