Surgery for acoustic neuroma is minimally invasive. As the acoustic neuroma is located in the pontine cerebellar angle, the anatomical relationship is complicated and important, so it is relatively difficult and time-consuming to perform the surgery. The location of the lesion is mainly in the posterior cranial fossa, which is the place where the brainstem is located, and it is also the circulatory pathway of the cerebrospinal fluid, so this kind of surgery is relatively complicated. However, with the continuous progress of medical technology and the development of microscopic neurosurgery, most of the clinical auditory neuroma surgeries are carried out under electrophysiological monitoring, which can protect the cerebral nerves as well as important blood vessels very well, and therefore, auditory neuroma surgeries belong to a kind of minimally invasive surgeries nowadays.
