  • Title: Retrolabyrinthine transtentorial approach to lesions of the anterior cerebellopontine angle.
    Author: Kinney SE, Hughes GB, Little JR.
    Journal: Am J Otol; 1992 Sep; 13(5):426-30. PubMed ID: 1443077.
    Abstract:
    Various surgical approaches to the cerebellopontine angle have been used for removal of acoustic neuromas. A retrolabyrinthine transtentorial approach has been developed that allows (1) access to the anterior cerebellopontine angle and all portions of the basilar artery, (2) extra dural retraction of the lateral sinus and cerebellum while avoiding the vein of Labbé, and (3) preservation of hearing. This approach allows good exposure of tumor and accurate visualization of cranial nerves. To avoid complications, control of spinal fluid is mandatory and great care must be taken to avoid injury of the cranial nerves. The retrolabyrinthine or translabyrinthine transtentorial approach enables skilled neurosurgeons and neurotologists to gain access to lesions that are located in areas difficult to approach.
