that is a otoneurologist
An otoneurologist should be the ideal person to treat migraine-related dizziness, but I think it really depends on the practitioner and their knowledge and interest. I don't think all otoneurologists are created equal in their knowledge of and interest in vestibular migraine. Certainly the same with neuro-otologists (also spelled neurotologist). An otologist is an ear specialist generally; a neuro-otologist is a specialist in the INNER ear (including dizziness and hearing loss).
