title: Diagnosis and documentation of central nervous system dysfunctions with craniocorpography after surgical removal of acoustic neurinomas.
abstract: Among other tests, craniocorpography (CCG) was performed in 21 patients after acoustic neurinoma surgery. After surgery, 17 patients (81%) had a developing vestibular compensation or an already normal CCG pattern; 3 patients (14%) had signs of persisting central nervous system dysfunction, either localized to the brain stem or in combination with a cerebellar dysfunction, and 1 patient showed a delayed but sufficient compensation after removal of a neurinoma that compressed central nervous system structures. Brain stem and cerebellar dysfunctions caused by tumor compression demonstrated a better vestibular compensation than dysfunctions caused by surgical manipulation, despite no evidence of cerebellar alteration. As an adjunct to complete neuro-otologic and neurologic examinations CCG could become a useful tool in the topodiagnosis of central nervous system dysfunctions after acoustic neurinoma surgery and therefore in the documentation and follow-up process of these patients.
