Retractorless CP Angle Surgery in Supine Position

Abstract

Background: The cerebello-pontine angle hosts a variety of pathology. A suboccipital retrosigmoid approach enables to tackle such pathology by minimal invasive access. For this approach a variety of positions have been used. We describe a dissection technique that circumvents the use of any brain retraction by careful supine patient positioning and cisternal opening by combining well-known microneurosurgical principles.
