Maxillary Nerve Block for Trigeminal Neuralgia
Maxillary neuralgia is caused by the compression of second division of the trigeminal nerve arising from the ganglion either by a vascular loop or a tumor resulting in pain in upper jaw. Pain due to maxillary nerve compression is characterized by brief attacks of excruciating pain, usually described as being sharp shooting or electric in character, involving the distribution of maxillary nerve, namely the lower eyelid, cheeks, lateral nose, and upper lip. Painful attacks are triggered by jaw movement, smiling, chewing or speaking.
