Hemifacial spasm secondary to vascular loop compression: a rare case report.

Oral Radiol 2018 Sep 20;34(3):273-276. Epub 2017 Jun 20.

Department of Oral Medicine and Radiology, SDM College of Dental Sciences and Hospital, Dharwad, Karnataka, 580009, India.

Hemifacial spasm (HFS) is characterised by brief, persistent, involuntary paroxysmal contractions of the facial muscles innervated by the facial nerve. Broadly its aetiology is portrayed as primary and secondary. Primary HFS is a result of vascular compression of the ipsilateral facial nerve at its root exit zone, and secondary HFS can occur after any injury to the facial nerve from the internal auditory canal to the stylomastoid foramen, which may be a result of a cerebellopontine angle tumour, schwannoma, fusiform aneurysm, or demyelinating lesion such as multiple sclerosis.

MD (Med), DM (Neuro), FRACP, Neurologist, Staff Specialist, Canberra Hospital.

Background: Botulinum neurotoxin (BoNT) is an exotoxin that causes neuromuscular weakness. BoNT serotypes A and B have been used for decades for the safe and effective treatment of various movement disorders, including some forms of focal dystonia. These conditions, such as cervical dystonia, hemifacial spasm, blepharospasm and spasmodic dysphonia, can have a substantial impact on patients' quality of life, but are often under-recognised.
