Trigeminal Neuralgia - Causes and Symptoms

Trigeminal Neuralgia

The trigeminal nerve receives sensation from the face, each of the two trigeminal, right and left, for the corresponding half of the face.

Causes of Trigeminal neuralgia

Therefore, the irritation of this nerve is clinically manifested by neuralgic type pain that extends across the face when the two trigeminal nerves are irritated at the same time (this is usually quite rare), whereas the symptoms corresponds to the facial neuralgia half when located in the three roots of one of the two trigeminal nerves, eventually affecting well-circumscribed partial areas of the face when injured one or two of the branches of the trigeminal nerve.

Irritation of the first branch leads ophthalmic neuralgia, which corresponds to the area of ​​the eye and the supraorbital region.

The irritation causes the second branch suborbital neuralgia, with the epicenter of maximum pain in the zygomatic region and the constant involvement of the teeth of the upper arch.

Irritation of the third leg, neuralgia appears mandible (jaw), teeth of lower jaw, tongue, lip, chin, lower face and ear.

Other possible causes of trigeminal neuralgia or facial neuralgia is:

  • Decayed teeth. Inflammation of the bony walls of the tooth socket (alveolar osteitis) when empty by fall of the respective tooth (facial neuralgia toothless)
  • Inflammation, usually chronic, of the nasal passages (rhinitis) and sinuses (sinusitis), eyes (oftcamia), ears (otitis).
  • Inflammatory processes (osteitis osteoperiostitis), tumors, exostoses (bony lush productions).
  • Fractures, etc.., The various bones of the face or skull with a contiguous relationship with the trigeminal nerve or one of its branches.
  • Intracranial tumors and exudates meningíticos intracranial compressing the nerve path, etc..

Symptoms of trigeminal neuralgia

All the above conditions result in compression, stretching and irritation of the trigeminal, and as such can produce neuritic phenomenon. The pain, which appears as more or less frequent access or distanced, reaches a high intensity that the patient is defined as burning or stabbing type.

Access painful it usually lasts a few minutes, but can be repeated more than ten times in the course of a day, can arise spontaneously or due to minimal, such as chewing, drinking, swallowing, coughing, sneezing, nose blowing, the burping, the local pressures mild exercise (such as washing your face, teeth, hair, etc..), receiving a stream of cold air, and even the glare with a bright light when it comes to the first branch of trigeminal (ophthalmic).

This is the reason that people with trigeminal neuralgia want a dark room and away from the noise, avoiding conversation, trying not to cough, sneeze or yawn, avoiding food and refrain from washing your face, teeth and comb.

Besides pain may occur:

  • Pale red unforeseen
  • Hypersalivation, hypersecretion of tears and sweat
  • Rash of small blisters in the form of herpes

In chronic neuralgia can occur over years hair loss in certain areas of the head and beard.
