>> Pituitary tumor:
Pituitary tumor is a pathological proliferation of cells in the pituitary gland, which is the main gland that secretes hormones into the body. It is sized as a pea and is located in the center of the brain behind the nose and eyes. Hormones are chemicals that the body produces in order to control and regulate specific cells and organs.
A tumor in the pituitary gland can disrupt the normal balance of hormones in the body. This can make man sick.
Pituitary tumors account for 10% of the primary brain tumors. Only a small number of pituitary tumors are malignant tumors. However, due to the location of the pituitary gland at the base of the skull, a pituitary tumor develops upward. Eventually, some tumors of the pituitary will push the optic nerves causing visual disturbances.
Many pituitary tumors are small, do not cause any health problems and may never need treatment. Almost all pituitary tumors can be treated, usually with medication and surgery.
There is no clear cause for pituitary tumors.
Some tumors of the pituitary can be caused by hypothalamus stimulation, a region of the brain, which sends commands to the pituitary gland to produce hormones.
>> Diagnosis:
- By physical examination, patient questions.
- By brain imaging MRI.
- With blood and urine tests.
- With biopsy.
Surgery is the most common way to treat pituitary tumors. Ways of Surgery:
>> Endoscopic Bladder Surgery
The neurosurgeon can remove almost all benign tumors of the pituitary gland using endoscopic burglar surgery. This minimally invasive technique allows neurosurgeons to:
- Remove the tumors and lesions through the nose and bones, without incisioning the face or scalp.
- Reach areas of the brain, which are difficult to access with classical surgery.
The neurosurgeon performs the surgery using an endoscope, a small telescope like a small telescope, featuring a high-resolution camera and powerful light. To remove the volume or to take a sample (biopsy) use special tools.
The advantages of endoscopic burglar surgery are:
- Less pain and faster recovery than classic surgery.
- It does not leave a visible scar on the face or scalp.
- It allows the patient to start radiotherapy, if necessary, almost immediately, without waiting for the incisions to heal.
>> Craniotomy
Another type of surgery to remove the pituitary tumor is called craniotomy. The surgery is performed by incision in the scalp of the patient's head and by removal of a part of the skull. Then the neurosurgeon can locate and remove the tumor or as much of the tumor can without the risk of severely damaging the brain. The neurosurgeon then reposition the bone and sutures the skin cut.
