Schwannomas intracraneanos: nuestra experiencia (2000-2009) / Intracraneal schwannomas: our experience (2000-2009)

ABSTRACT

Objective. To present and evaluate the surgical results in the treatment of intracranial schwannomas. Method. We present 26 patients with intracranial schwannomas for a period of 10 years treated with surgery, analyze kind ofpresentation and postoperative results. Results. One of the cases corresponded to schwanoma of III pair, another case to schwanoma of the V pair, two other cases corresponded to schwanoma of the IX pair and twenty two cases corresponded to schwanomas of the VIII pair. Average age was 51,95 años (19-73). Total resection was made in 25 patients, partial resection was made in other. Facial nerve preservation was made in the remaining 22 patients. Preservation auditory nerve function was made in all the cases. We had 3 cases of cerebrospinal fluid leak.There were no mortal cases associated to the surgical procedure. Conclusion. The goal of treatment of intracranial schwanomas is total resection with anatomical and functional preservation of neurological structures around. This could be accomplished by retrosigmoid approach by experienced neurosurgeons.(AU)
