Abstract

Background and Importance: Severe hemifacial spasm caused by compression by a tortuous vertebral artery (VA) often is encountered and is difficult to treat. We describe a patient with hemifacial spasm caused by compression of the facial nerve by a tortuous VA. A simple and effective transposition approach, a "double-stick tape" technique, to the offending artery using a fibrin tissue-adhesive collagen fleece product (TachoComb) is reported. Clinical Presentation: A 65-year-old woman presented with an 8-year history of right-sided facial spasms, including the orbicularis oculi and orbicularis oris muscles. MRI revealed a tortuous right VA indented into the pontomedullary junction. The right anterior inferior cerebellar artery (AICA) also contacted the proximal portion of the facial nerve. Surgical exploration with standard retrosigmoid craniotomy was performed. The offending VA was dissected away from the pontomedullary junction toward the cranial base. A small piece of TachoComb, with fibrin glue applied on the non-coated side of the fleece to make a "double-stick tape," was then placed on the ventral surface of the VA. Until the glue hardened, the VA was held away from the brainstem onto the dura of the petrous pyramid. After this procedure, AICA transposition was performed. The patient's symptoms were completely resolved immediately after surgery, and she remained asymptomatic at her 1 year follow-up visit. Conclusion: The advantage of our "double-stick tape" technique is the simplicity of the procedure. The present technique is a feasible alternative for the treatment of hemifacial spasm caused by a tortuous VA.
