Tokyo) introduce, describe, and promote the retrosigmoid approach not only for otologists but for any surgeon dealing with pathologies of the cerebellopontine angle.
The last five chapters detail the fully endoscopic endonasal approach, the fully endoscopic transglabellar approach, the fully endoscopic supraorbital approach, the fully endoscopic retrosigmoid approach
, and the fully endoscopic subtemporal approach.
The results can be used to correctly locate the IMTS during the retrosigmoid approach
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:
Both procedures are performed via the retrosigmoid approach
during the same surgical step.
