What different kinds of surgery can be done to treat acoustic neuromas?

Isaac Yang, MD
Neurosurgery
Doctors use three different types of approaches for acoustic neuroma surgery. These are middle cranial fossa (MCF), retrosigmoid (RSA) and trans-lab (TL). Research shows that trans-lab surgery has a higher rate of cerebrospinal fluid (CSF) leaks but lower rates of cranial nerve complications. Retrosigmoid approaches have a lower rate of CSF leaks. If people have their hearing intact and want to save their hearing, a retrosigmoid approach is generally used. A trans-lab approach is used for people whose hearing has already been lost, because if a trans-lab approach is done in a person who has his hearing intact, his hearing will disappear.
