Microvascular transposition using Teflon sling technique Mitchell W. Couldwell, MSc, Vance Mortimer, AS, and William T. Couldwell, MD, PhD Department of Neurosurgery, Clinical Neurosciences Center, University of Utah, Salt Lake City, Utah Microvascular decompression is a well-established technique used to relieve abnormal vascular compression of cranial nerves and associated pain. Here the authors describe three cases in which a sling technique was used in the treatment of cranial nerve pain syndromes: trigeminal neuralgia with predominant V2 distribution, hemifacial spasm, and geniculate neuralgia and right-sided ear pain. In each case, the artery was mobilized from the nerve and tethered with a sling. All three patients had reduction of symptoms within 6 weeks.
