After the evacuation of the contused brain, they repaired the dural tear with
pericranial fascia.
However, blocking of other
pericranial nerves and ganglia was not effective (5).
Wide excision of the mass followed by a
pericranial flap was performed.
Some of the proposed trigger mechanisms of a cervicogenic headache are compression or inflammation of the C2 nerve root; referred pain of the first branch of the trigeminal nerve from C2 nerve root irritation trough anastomosis; emerging pain in the trigeminal nerve area caused by stimulation of the upper spinal nerve roots from the anatomical connection between the spinal trigeminal nucleus and dorsal horn at the C2-3 spinal level [5] (Figure 1); a tension headache due to entrapment of the occipital nerve after
pericranial muscles constrict from cervical muscle strain or spasm.
Periosteal elevators are used to elevate the periosteum and create a
pericranial flap that extends to the supraorbital rim to be used if needed.
[3] Migraine pain can also originate in the
pericranial muscles.
The results show that there are significant differences in the activation of the frontal and central right
pericranial regions depending on the type of autobiographical memory recalled in the 2.5 second prior to the memory retrieval.
It is widely accepted that excessive muscle activity in
pericranial muscles is of great importance for the development of TTH, as reflected in the term of muscle contraction headache.
Since pain during craniotomy and in post-operative period are due to a large extent from scalp and
pericranial muscles, blocking the sensory nerve fibres from these areas can reduce total anaesthetic requirement enabling early recovery and also reducing post-operative analgesic requirements.

pericranial myofascial trigger points in the treatment of frequent episodic tension-type headache.
