Retrosigmoid suboccipital access has been widely used in neurosurgical care for more than a century. It has been employed in different vascular diseases and tumors of the brain. The authors provide examples of how to use the retrosigmoid suboccipital access, a patient's position during its application and techniques. All stages of performance of the access, including trepanation of the internal acoustic meatus, are considered in detail. Emphasis is laid in the advantages and disadvantages of this access. The basic stages of the access are illustrated. Correct application of the retrosigmoid suboccipital access is stated to yield a good view of primarily the cerebellopontile angle and causes no its associated complications.
