Main Neuralgias in Otolaryngology
Journal Title: Scholarly Journal of Otolaryngology - Year 2018, Vol 1, Issue 4
Abstract
The headache and neck are mediated by sensory fibers transmitted some cranial nerves, trigeminal, intermediary nerve, vagus and upper cervical spinal roots through the occipital and auricular nerves [1]. Nerve pain may have paroxysmal quality, which is usually of maximum onset and is often described as excruciating, similar to electric shock or puncture. There may be a single acute pain or repetitive aches in succession. The pain may last a fraction of a second or last several seconds. There may be a refractory period after severe pain during which pain will not occur. The mechanisms of neuropathic pain are complex. A nerve injury can induce peripheral and central changes that contribute to persistent pain and abnormal sensation. These processes end in normal circumstances as tissues heal and inflammation decreases [2]. Trigeminal neuralgia is one of the most common causes of facial pain. The pain tends to appear in the paroxysms and is maximum at the beginning. The pain has been described as an electric shock or puncture. Trigeminal painful neuropathy is defined by the head and/or facial pain in the distribution of one or more branches of the trigeminal nerve caused by another disorder and indicative of neural damage potential causes include acute herpes zoster, post herpetic neuralgia, and Trauma. Post-herpetic neuralgia is defined as the pain that persists between one and six months after the acute herpes zoster eruption has healed [1,2] painful posttraumatic trigeminal neuropathy, also known as painful anesthesia, is characterized by unilateral facial or oral pain that occurs after a traumatic trigeminal nerve injury, accompanied by additional symptoms or signs as a nerve dysfunction [1,2]. This condition is a perfect example of how difficult it can be to describe the central pain as the patient has a sensory loss, but at the same time may feel pain. In painful anesthesia, the pain overlaps in an area of the face that is lacking or has a sense of deterioration.
