Introduction: Hemifacial spasm (HFS) is characterized by the involuntary, paroxysmal, painless, and progressive spasmodic contractions of facial muscles innervated by the ipsilateral seventh cranial nerve. To date, neuroimaging studies (Computed Tomography scan [CT] and Magnetic Resonance Imaging [MRI]) are unable to establish the diagnosis. HFS medical treatment with antiepileptic drugs, and Botulinum toxin application are temporarily effective, however, both have shown side effects and lesser cost-effective results. Currently, surgical Micro Vascular Decompression (MVD) for HFS has the highest curative rates and lower operative morbidity. We analyze the demographics, clinical manifestations, outcomes, and complications that to our knowledge, is the largest …
