Cranial giant cell tumor resection

Giant cell tumor of the bone is rare in the skull. It is more common in the skull base involving the sphenoid bone, rock bone and ethmoid bone. The tibia, frontal bone and occipital bone are also visible. It happens in young adults aged 20 to 40. The whole course is slow, and there is only slight discomfort or pain in the early stage of the onset of the disease. However, with the continuous development of the tumor, it can be a cyst of different sizes or huge, and cause more severe pain and headache. If it is invaded to nearby tissues or the brain, symptoms of focal symptoms and increased intracranial pressure may occur. If the sella or nearby tissue is involved, visual impairment, hemianopia, and trigeminal and oculomotor involvement may occur. Observed from X-ray films, it can be expressed as polycystic, monocystic or cystic. Giant cell tumors are locally destructive and active, also known as osteoclast. Mostly located in the midline and midline of the skull base, the surgery is not easy to completely remove. In general, it is advisable to have a clear diagnosis, surgical resection, and then followed by radiotherapy. Treatment of diseases: giant cell tumor of the skull Indication 1. Diagnosis of giant cell tumor, local discomfort, severe headache, or affect the appearance of the person. 2. The tumor invades the cranial cavity and produces symptoms of brain compression and intracranial hypertension. Preoperative preparation Pay attention to the relationship between the tumor and the intracranial and nearby tissues, prepare the skull bone forming material, and prepare blood. Surgical procedure Incision A flap incision is usually used. The skull incision is tumor-centered. Tumors located in the midline or midline of the skull base are often treated with low or frontal craniotomy. 2. Reveal the tumor A tumor located in the calvarial can be seen when the flap is opened. Tumors located at the base of the skull need to be explored along the bottom of the brain after the flap is opened to detect the tumor. 3. Tumor resection Before the resection of the skull cover tumor, several skull holes should be made 1 to 2 cm around the talus tumor. The bone between the holes should be sawed or excised with a wire saw, a milling cutter or a rongeur. The bone flap is removed together with the tumor. Reach a cure. The midline of the skull base or the midline tumor, due to important structures in the adjacent parts, such as the cavernous sinus, internal carotid artery and the 2nd to 6th cranial nerves, the total tumor is often difficult to cut, but in the development of skull base surgery and microsurgical application The rate of total and subtotal resection of the tumor has been significantly improved. 4. Incision suture After the removal of the giant cell tumor of the skull, the skull defect can be repaired in one stage. After the removal of the tumor at the base of the skull, the craniotomy was performed according to the craniotomy of the bone flap. complication 1. The cerebrospinal fluid rhinorrhea is mostly caused by the removal of the dura mater at the base plate of the tumor, or the result of the frontal sinus opening and improper treatment during craniotomy. 2. Optic nerve, anterior cerebral artery and its branch damage.
