Overall, the surgical bone window is small, with less bleeding and faster recovery time, and it is a less traumatic and painful surgery among neurosurgeries. Postoperative headache and nausea will be mainly caused by cerebrospinal fluid release and cranial pressure reduction, which can be relieved by bed rest for several days and adequate fluid replacement. However, because the surgery is performed near the brainstem and the facial nerve is closely related to the auditory nerve, there is still a small probability of risk and complications, so treatment at a high-level neurosurgery center is recommended.
