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.
