Abstract

|
Traditional surgical approaches to larger than medium-sized vestibular schwannomas (VSs) were retrosigmoid suboccipital craniotomy in neurosurgical area. The approach has plenty of advantages for these tumors, however, several disadvantages such as cerebellar retraction injury, postoperative headache, hydrocephalus, etc. Therefore, most of otolaryngologists and some neurosurgeons have used posterior transpetrosal approaches like translabyrinthine one to diminish the above complications. The selection of the surgical approaches is not the issue of the department, but the experience as well as rational basis. Thus, I reviewed these approaches for the medium- or larger VSs to understand how to choose the appropriate approaches.
