Are there any side effects after Gamma Knife surgery for acoustic neuroma?

There is a possibility of complications after Gamma Knife surgery for acoustic neuroma, but the likelihood is relatively small.

Gamma Knife treatment for acoustic neuroma offers several clinical advantages, primarily due to its safety, reliability, and high precision. However, like any surgical procedure, it carries some risks. While Gamma Knife targets the tumor effectively, it may also cause damage to surrounding nerves, potentially leading to complications such as hearing loss or facial paralysis. Under a doctor's guidance, patients can take neurotrophic medications—such as mecobalamin and vitamin B1—to promote nerve recovery. Most patients experience varying degrees of improvement within a few years. Additionally, localized edema may occur, causing symptoms like nausea, vomiting, and headache, although these are usually reversible and resolve over time. It should be noted that the probability of such complications is low, so patients need not be overly concerned.

After Gamma Knife surgery for acoustic neuroma, patients should follow their doctor’s instructions for regular follow-up examinations to monitor for tumor recurrence or regrowth.
