Endoscopy is another excellent method for brain surgery. It allows access to inaccessible areas of the brain where certain kinds of tumors develop. Endoscopy and endoscope assisted brain surgery one of the latest techniques which is safe and fast.
The surgical method of treatment for tumors is often recommended technique. The endoscopic surgery is the most opted surgical method for the tumours on the base of skull, like PITUITARY ADENOMA, CLIVAL REGION TUMOUR, etc. The endoscopy based surgeries leave no scars as in conservative open surgery. The endoscopic method do not make any incisions on the skull or any other part of body. The surgery is initiated through natural opening such as mouth or nostril. This avoids pressure in the brain. This technique makes use of highly specialized instruments and a high definition endoscopic camera system. Both benign tumors and Malignant are treated through this method.
Initially, an endoscope is inserted through the nose. This prevents the need for incision in the skull part to access brain give a better highly illuminated inverted cone magnified view of the base of skull. Usually a high-speed debrider is inserted along with the endoscope. The debrider is used to clear the soft tissue from the surgical pathway, The base of skull is drilled using high speed medical drills to gain good exposure and in some cases as meningioma to devascularize the tumour. Thus tumors point of attachment is exposed. Both the endoscope and the instrument is used at the same time during surgery using four hand two surgeon technique of “Carrau and Kassam”. The manipulation of the endoscope provides adequate visualization of the tumor. The tumor is then removed with clear margins. After the removal, the reconstruction of the skull base is performed using vascular pedicle grafts with or without bone graft. The tissue grafts accumulated from other parts of the body may also be used for reconstruction. Tissue glue is used to hold the tissues in place. The discharge from hospital is usually possible within 2-4 days after surgery. This technique has the advantage of providing the highest rate of resection with minimal morbidity.
