Nerve blockade method is an interventional treatment.
It can be used as a preventive measure in preventing migraine attacks, as well as methods that can be used during headache attacks.
Brain centers responsible for migraine attacks (such as the trigeminovascular system). It is based on the principle of administering various drugs (such as bupivacaine, lidocaine, triamcinolone, etc.) to the nerves thought to be related to headache with special injection techniques and thus blocking the nerves. , supraorbital nerve, supratrochlear nerve, auriculotemporal nerve etc.) can be applied simultaneously.
However, it is most commonly performed on the nerve called the greater occipital nerve (GON) and this process is briefly referred to as 'GON Blockade'.
Because this nerve is directly related to the trigeminovascular system, which is the brain region responsible for migraine attacks.
GON BLOCKAGE
It has been shown to reduce the frequency, severity and duration of migraine attacks.
For this reason, it can be used as a preventive treatment during migraine headache attacks and to prevent migraine attacks.
How does it work?
Drugs applied to the greater occipital nerve with special techniques and sometimes with the help of ultrasonography They block the reversible sodium channels in the fibers.
Thus, the formation of pain stimuli in the (trigeminvascular) region to which the nerve is connected and associated with migraine headache is prevented.
Nerve blockages also prevent migraine in the nervous system. A regulatory effect (modulation effect) is also provided against the mechanism that creates the pain.
How is it done?
GON Blockade is applied to the back of the head. (picture)
The nerve is detected with the help of anatomical structures at the back of the head.
Sometimes it may be necessary to use ultrasonography to find the nerve.
After the greater occipital nerve is found, various injection techniques are used. A mixture of local anesthetic and serum prepared in doses is injected.
It can be applied unilaterally or bilaterally.
After the injection, numbness and temporary loss of sensation occur in the applied area.
The procedure can be performed easily in a clinical environment.
How often should it be done?
Generally, it can be done for 3-5 weeks consecutively, with a one-week break.
Afterwards, monthly applications can also be done.
However, it can be done 'repetitively'. It has been shown that GON Blockade applications significantly reduce the frequency, severity and duration of migraine attacks!
For this reason, it can be used in migraine headache attacks as well as for the preventive treatment of migraine.
Which patient, which It should be decided by the neurologist on an individual patient whether it will be applied at intervals.
Does it have any side effects?
When administered in competent hands, in accordance with the rules and carefully, side effects are very rare.

Side effects such as injection site infection, subcutaneous bleeding, feeling of fainting, decrease or increase in blood pressure, and nausea may occur in injections made to any part of the body.
Very rarely, local anesthesia is used. Depending on the substance, hypersensitivity, heart rhythm disorders, allergic reactions, etc. side effects may occur.
If steroids are used along with local anesthetics during GON blockade, side effects such as hair loss and skin thinning may also be observed.
If GON blockade will be used for the treatment of headaches in pregnant women, steroids may be observed. It is not recommended to use it.
