Craniotomy Surgery–Foremost Approach in Brain Cancer Treatments

Surgery for removing tumor is often the first step in Brain cancer treatments adopted by neurosurgeons for removing majority of the tumor that is deemed risk-free while sparing normal brain functioning.

Surgery by itself or merged alongside radiation therapy might be used in brain cancer treatments for several tumors inclusive of a number of ependymoma, craniopharyngioma, ganglioglioma, low grade astrocytoma and meningioma forms.

Tumors which have a tendency to spread into adjoining tissues in the brain like glioblastoma or anaplastic astrocytoma are incurable through surgical intervention. However, surgery could lessen the extent of tumor which would need to undergo chemotherapy or radiation therapy that could aid in improving the efficacy of such therapies. This might assist in prolonging life even though total tumor removal would not be possible.

Surgery could be one of the most viable brain cancer treatments that might additionally assist in improving a number of symptoms arising due to brain tumors, especially those that arise due to pressure build-up inside the cranium which could comprise of headache, feeling nauseous, puking and blurry eyesight. Surgery might additionally be helpful in controlling seizure attacks.

However surgery might not be an ideal choice in several scenarios. For instance, when the tumor is quite deeply set inside the brain or the patient is incapable of tolerating a major surgery due to other health concerns. Surgery is additionally not performed in case it would need removal of some portions of the brain needed for existence like brain stem.

Surgery is also not quite effectual in case of a number of brain tumor types like lymphoma, though it might be employed for acquiring a biopsy for identification.

Craniotomy- This is the key form of surgery to treat brain tumors and cranium would be opened during the procedure after anesthesizing the patients (general) for promoting deep slumber. Alternately the patient could be wakeful for some portion of the surgery (with the operated region de-sensitized) in case brain functioning is to be evaluated during the course of the surgery. Shaving of a section of the brain might become necessary. Firstly, a slit would be made in the scalp and folding back of the skin would be done by the surgeon. The neurosurgeon would then employ a specially designed saw-like apparatus for removing a part of the cranium that is above the tumor.

Craniotomy is classically large-sized to enable the neurosurgeon in inserting a number of apparatus and viewing sections of the brain required to manoeuvre with complete safety. In case of deeply located tumors in the brain, a tiny slit would be done into the brain for facilitating easier accessibility to the tumor. CAT, ultrasound or Magnetic resonance imaging (MRI) could be employed to assist in locating the tumor and its borders.

Tumor removal is done in numerous ways based on the hardness or softness and if it has several or hardly any blood vessels. One approach would be using a scissor or scalpels for incising it out or ultrasonic generator device fitted onto a probe that might be introduced inside the tumor for breaking it up and liquefying it. A small-sized vacuuming apparatus would now be employed for suctioning it out.

Several apparatus could be of assistance to the neurosurgeon for seeing the tumor and adjoining brain tissues. A microscope could be employed for viewing the brain when the operation is being done. Image-steered surgery involves repetitive capturing of the tumor images during the surgery for revealing the tumor site and the neurosurgeon’s tools. This could facilitate risk-free and vastly far-reaching resecting of a number of brain tumors.

The neurosurgeon could view brain functioning via electrical stimulation of areas of the brain in and adjacent to the tumor and would help in showing whether such parts are controlling vital functioning.

Intraoperative cortical stimulation is a method used for lowering risk of removal of crucial brain portions. Functional MRI is another method employed for locating some brain function before operation which would help in identifying and preserving the area during surgery.

Mostly, the bone portion that has been taken out would be placed back and affixed to the cranium employing metallic screw, plate, wire or specialized stitch types. The operated side would heal in a number of weeks and recuperation in hospital is generally around four to six days depending on the size, how big the tumor was and the overall health condition of the patient.
