Even the smallest mistake made in surgeries performed on the brain and spine can cause paralysis. Neuromonitoring technology is one of the high-end technologies used in such surgeries.
What is Neuromonitoring?
A neuromonitoring system is used to minimize the risks of brain and spine surgeries. With the intraoperative neuromonitoring method, the surgeon is warned by detecting the damage that may occur in the nerves during the operation.
In which diseases is neuromonitorization used?
The neuromonitoring system can be used mostly in the operations of the brain, nerve, and spinal cord surgery department and in some operations of the otolaryngology and general surgery departments.
- Stimulation of Spine Screws
- Trigeminal Neuralgia
- Cerebrovascular diseases such as AVM (Arteriovenous malformation), hemifacial spasm
- Spinal tumors and spinal diseases
- Scoliosis surgeries
- In some surgeries for ear and nose diseases such as laryngeal cancer and salivary gland cancer surgeries,
- Thyroid surgery can be done with neuromonitoring.
Benefits of the Neuromonitoring System (Differential features)
Tumors located in sensitive areas of the brain or removal of spinal cord tumors always carry the risk of stroke. After brain tumor surgeries, patients may experience problems with motor functions such as feeding, walking, and speaking, which are called “motor functions.” In such risky surgeries, the neuromonitoring system warns the surgeon during the surgery, making the surgery much safer. Complications after surgery are minimized.
One of the most important problems in sensitive spine surgeries such as scoliosis and removal of spinal cord tumors is the risk of paralysis during the operation. The effects of the intervention in previous surgeries on the spinal cord could not be understood. The patients were awakened towards the end of the operation, and the effects of the intervention on the spinal cord were checked. In addition to this procedure being troublesome for the patient, it was also too late for a second intervention. In these surgeries, the use of a neuromonitoring device that continuously displays the state of the nerves prevents possible nerve injuries.
Frequently Asked Questions About Neuromonitoring
How is the patient prepared for the neuromonitorization application?
Before starting the operation, electrodes are placed on the faces, arms and legs of the patient, who is brought to the operating room environment and put to sleep. Signals received from these electrodes during the operation are followed by the surgeon.
When there is a decrease in the signal received from the muscles, the neuromonitoring device informs the surgery by giving a warning about the sensitive area.
In surgeries using neuromonitoring, the system must be in harmony with anesthesia. It is important that the anesthesia, which paralyzes the muscles, is not too deep in this type of surgery. The return of the electricity given to the muscles is important for the signals to be received from the neuromonitoring device.
Neuromonitorization, or long-expression in the name, during surgery provides intraoperative neurological monitoring and control of nerve conduction. Thus, electrical signals affected by compression or being under pressure can be detected and precautions can be taken before permanent damage occurs.
What are the benefits of performing surgeries with neuromonitorization?
The development of nerve injury during spine surgeries is a feared complication. Nerve injuries may develop due to screw placement errors or the inability of the spinal cord to tolerate the correction made in the spine. In the years when spine surgeries were just developing, nerve injuries were seen with a high frequency. However, with the developments in recent years and the use of neuromonitoring in surgery, the rate of nerve injury has decreased tremendously.
Neurological injury rates are high where high concentrations of spine surgery, the improved engine in the center, in the hands of experienced surgeons, and preferably less neuromonitorization, are made with the control. In addition, screw errors have been further reduced with the navigation technology that has been developed in recent years and is used in a small number of centers.
