Abstract: Targeted Peripheral Nerve-Directed Onabotulinumtoxin A Injection is an Effective Long-Term Therapy for Migraine Headache

Background: Migraines affect 28 million people in the United States. Surgical treatment for migraine headaches refractory to medical treatment has grown recently for patient with limited options. Utility scores are standardized tools offering validated means of measuring the health state preference of a health condition or disease state. The aim of this study was to prospectively determine the impact of the health state burden prior to surgical treatment, to characterize the quality of life for this patient population.
