Summary
Trigeminal nerve root section effectively treated chronic migrainous neuralgia in 85.7% of patients. This surgical option offers significant pain relief and improved quality of life for those with refractory symptoms.
Area of Science:
- Neurosurgery
- Pain Management
- Neurology
Background:
- Chronic unremitting migrainous neuralgia is a debilitating condition.
- Symptoms persist for over 18 months, refractory to medical treatments.
- This condition significantly disrupts patients' lifestyles.
Purpose of the Study:
- To evaluate the efficacy of trigeminal nerve root section for chronic migrainous neuralgia.
- To assess pain relief and long-term outcomes after surgery.
- To determine the safety and effectiveness of this surgical intervention.
Main Methods:
- A series of 14 patients with chronic migrainous neuralgia underwent partial or complete trigeminal nerve root section.
- Surgical approaches included complete division or partial division (50-90%) of the superomedial sensory root.
- Patients were followed up to assess pain relief, recurrence, and complications.
Main Results:
- 85.7% of patients (12 out of 14) experienced adequate pain relief and improved quality of life.
- Complete trigeminal nerve root section provided complete pain relief in 2 patients.
- Partial section resulted in complete to incomplete relief in 5 patients, with 7 requiring further surgery or experiencing recurrence. Post-second surgery, 5 patients achieved pain freedom or near-complete relief.
- Corneal abrasion occurred in 28.5% of cases, with one progressing to chronic keratitis.
Conclusions:
- Total trigeminal nerve root section is an effective treatment for chronic migrainous neuralgia.
- Surgery can be safely offered as a primary treatment option for selected patients.
- The procedure leads to significant pain reduction and restoration of normal life activities.

Cranial Nerves: Overview and Anatomy
The cranial nerves are an important part of the complex network of nerves in the human body. These nerves emerge directly from the brain and are responsible for transmitting essential information between the brain and various parts of the head and neck. There are 12 pairs of cranial nerves, systematically numbered using Roman numerals from I to XII, beginning from the anterior and moving to the posterior of the brain. Each cranial nerve is uniquely identified by names that reflect its function...
Cranial Nerves: Types Part I
Cranial nerves are responsible for transmitting motor and sensory information between the brain and various parts of the body. There are twelve pairs of cranial nerves, with the first six being essential in sensory perception, motor control, and autonomic functions related to the head and neck.
Olfactory Nerve (Cranial Nerve I)
The olfactory nerve, or cranial nerve I, is unique as it is purely sensory and dedicated to the sense of smell. This nerve originates in the olfactory epithelium of the...

Cranial Nerves: Types Part II
Cranial nerves are responsible for transmitting motor and sensory information between the brain and various parts of the body. There are twelve pairs of cranial nerves. While the first six innervate the head and neck, the latter six nerves innervate the head and neck, as well as organs and tissues in the thoracic and abdominal cavities. They facilitate communication, expression, and autonomic control within the human body.

Sympathetic Pathways: Sympathetic Chain Ganglia
The sympathetic chain ganglia, also known as the sympathetic trunk ganglia or paravertebral ganglia, are a series of ganglia located bilaterally on either side of the spinal column. These ganglia serve as relay stations for the sympathetic nervous system. Preganglionic neurons originating in the spinal cord project their axons to the sympathetic chain ganglia. Within the ganglia, these preganglionic fibers synapse with postganglionic neurons.The postganglionic neurons of the sympathetic trunk...
Cranial Part of Parasympathetic Division
The cranial part of the parasympathetic division plays a crucial role in regulating the visceral functions of the head and specific structures in the neck, thoracic, and abdominopelvic cavities. Preganglionic fibers of the parasympathetic division exit the brain through cranial nerves III (oculomotor), VII (facial), IX (glossopharyngeal), and X (vagus), delivering parasympathetic output to the respective visceral structures.
