——Excerpt from the article chapter
【Ref: Franz L, et al.
Research background
Acoustic neuroma resection to preserve hearing is the key to current surgery, reaching the bottom of the internal auditory tract is an important aspect of resection of acoustic neuroma and hearing preservation in the after-sigmoid sinus, and the location of the open skull window is necessary to obtain full exposure to the bottom of the internal auditory tract and retain the labyrinthThe study retrospectively analyzed the clinical data

Research results
The results show that posterior medial craniotomy of the medial auditory canal-labiatic route has a higher chance of exposing the medial auditory duct floor (p=0.
Finally, the authors note that the location of the posterior siloidosis window correlates with the chance of exposure to the floor of the internal auditory tract; The posterior medial margin of the open cranial window is located at about 11 mm posterior medial of the medial canal floor of the endoes auditory canal- the labyrinth route, which maximizes the exposure of the medial auditory canal floor
