A random selection of 20 patients with pathological diagnosis including tumors ranging in size from 2 to 5 cm received endoscopic management. For some deep-seated brain tumors, like thalamic gliomas and malignant lymphomas, it is a potential approach for excision or biopsy. A procedure called neuroendoscopic biopsy is utilised to confirm the pathology of brain tumors by histology. The use of this technology has various benefits, including the ability to precisely view the tumor surface and avoid veins during tumour resections under direct vision. Another option is to gather enough samples for a pathology diagnosis. Since it made hemorrhages easy to stop, the two-handed endoscopic technique that made use of a mounted rigid endoscope was exceedingly effective and safe. The purpose of this study was to illustrate the function of endoscopy in the removal of deep-seated or intraventricular malignancies. A different medial approach is offered by the rigid endoscopic technique with a thick sheath, which offers better visualisation and a bigger working area.
