AbstractMost scalp neuralgias are supraorbital or occipital. Although they have been considered idiopathic, recent studies revealed that some were attributable to mechanical irritation with the peripheral nerve of the scalp by superficial anatomical cranial structures. Supraorbital neuralgia involves entrapment of the supraorbital nerve by the facial muscle, and occipital neuralgia involves entrapment of occipital nerves, mainly the greater occipital nerve, by the semispinalis capitis muscle. Contact between the occipital artery and the greater occipital nerve in the scalp may also be causative. Decompression surgery to address these neuralgias has been reported. As headache after craniotomy is the result of iatrogenic injury to the peripheral nerve of the scalp, post-craniotomy headache should be considered as a differential diagnosis.
