Following this step and finishing of the surgical procedures related to anesthesia, We selected patients having a mass located eloquent areas of the cerebrum or deep parts of it for stereotactic surgery for tumour removal. We pick up preoperative cranial magnetic resonance imaging (MRI) and cranial computerized tomography (CT) with contrast from all patients. The diagnoses were glioblastoma (n=2), metastatic non-small cell lung carcinoma (n=3), cavernous malformation (n=1), grade 2 meningioma (n=1), purulent abscess ( Table 1). Four of the patients were women, and four of them were men.
#Eloquent areas of brain archive#
We obtained all information regarding preoperative and postoperative clinical, radiographic, histopathologic, and operative records from the online archive of the Baskent University Medical Faculty Hospital. Moreover, we did these operations using computerized tomography assisted an arc-based CT compatible stereotactic frame system (Fischer ZD, Germany) at Baskent University medical center between 20. For their intracranial mass lesions, these patients underwent craniotomy and tumour removal surgery. The mean age of these patients was 56 and a standard deviation of 9.41.
Of these patients, brain tumours were settled in the eloquent cerebral regions -motor cortex, Heschl gyrus- or deep parts of the cerebrum.
#Eloquent areas of brain series#
Our series comprises nine craniotomies in eight patients with tumours at the cerebrum. To demonstrate the effectivity of the stereotactic craniotomy, we made nine consecutive stereotactic craniotomy in eight patients having intracranial mass located eloquent areas or deep parts of the brain with various pathologies, including glioblastoma, meningioma, abscess and cavernoma. Secondly, making less retraction to the brain provides less damage to brain tissue. These are firstly, making intersulcal incison or if it is possible to remove any tumour without touching cortical part of the cerebrum. While performing stereotactic craniotomy, there are fundamental advantages. So to prevent these complications, stereotactic resection of these tumours has been used for more than fifty years. Because of these damages, patients experience motor and sensory deficit, motor dysphasia, sensory dysphasia and various symptoms and signs related to damaged sites of their cerebrum. Intracranial tumours located at the eloquent areas and deep sites of the cerebrum have been difficult to treat surgically because of their high complication risks, including hemorrhagic infarct, cerebral tissue damage and bleeding. However, when we correlated this technique with MRI scans of the patients with CT compatible stereotaxy scans, it is possible to provide gross total resection and protect and improve patients’ neural functions. However, to use all of this equipment having these technologies would be impossible because of economic reasons. These techniques are magnetic resonance imaging (MRI), MRI compatible stereotaxis, frameless stereotaxy, volumetric stereotaxy, functional MRI, diffusion tensor (DT) imaging techniques (tractography of the white matter), intraoperative MRI and neuronavigation systems. Following CT compatible stereotaxic system applications in neurosurgery, different techniques have taken place in neurosurgical practice. Using of CT compatible stereotaxy for removing a cranial tumour is to be commended as a cornerstone of these technological advancements. So neurosurgery and technological advancement go hand in hand to realize this goal. Moreover, while protecting the neural function, a neurosurgeon should extract the maximum amount of tumoral tissue from the tumour region of the brain. The first goal in neurosurgery is to protect neural function as long as it is possible.
