Surgical Approaches to the Tentorial Hiatus

  • L. Symon
Part of the Advances and Technical Standards in Neurosurgery book series (NEUROSURGERY, volume 9)


Access to the tentorial hiatus presents the neurological Surgeon with more than usual difficulty. In addition to the depth of the exposure, and the necessity for considerable retraction of overlying brain, lesions lying in the region of the hiatus tend to involve vital areas of the brain stern and important cranial nerves. This chapter describes a series of approaches which the author has found helpful over the years in general neurosurgical practice, and while it is likely that most neurosurgeons will have occasion to use most of these exposures only rarely, several of them such as the extended anterior temporal approach to the anterior tentorial hiatus, and the combined supra- and infratentorial approach to the upper clivus, give remarkably good access for a variety of conditions, and may therefore be considered of unusual practical value.
