Transhorizontal Fissure Approaches to the Middle Cerebellar Peduncle: Quantitative Anatomical Analyses of the Retrosigmoid, Extended Retrosigmoid, and Presigmoid-Retrolabyrinthine Approaches
The PSRL- and xRS-transhorizontal fissure approaches were superior to the RS-transhorizontal fissure approach for all instrument maneuverability parameters in the posterolateral MCP. The former 2 approaches were preferable for access to lateral pontine CMs, especially those with dorsal extensions. The xRS approach compensates for disadvantages of the RS and PSRL approaches to achieve surgical corridors for extensive central pontine CM resection.
