Assessment of surgical efficiency in patients having posterior cranial fossa epidermoid tumors
Keywords:
epidermoid tumors, volume removal, mortalityAbstract
Based on the data from 35 epidermoid tumor cases (37 tumors located in cerebellopontile angle and 16 in the IV — the ventricle) the analysis of postoperative mortality was carried out with regard for the tumor volume and surgical radicality. The analysis revealed that subtotal tumor removal allows to considerably decrease postoperative mortality in cerebellopontile angle epidermoid tumors and exclude mortality in tumors of the IV — th ventricle.
It may be concluded therefore that the most appropriate method of posterior cranial fossa tumor removal is to remove a tumor subtotally leaving its small part closely tied to the brain structures unremoved.
