These leaks are usually the result of an iatrogenic injury during removal The retrosigmoid approach is commonly associated with leaks that occur through the lateral end of the internal auditory canal, through the perilabyrinthine cells extending to the region of the internal auditory canal, or through the retrosigmoid air cells.
Results: Petroclival region can be accessed through following approaches: petrosal, anterior and posterior combined approach, supra and infratentorial combined presigmoid approach, orbito-zigomatic infratemporal approach, suprameatal intradural retrosigmoid approach, pterional approach, retromastoid approach, subtemporal approach and combined subtemporal retromastoid approach:
