Trigeminal neuralgia is one of the most severe facial pain disorders known in medicine. Patients typically experience sudden, electric shock-like pain affecting one side of the face, often triggered by everyday activities such as speaking, chewing, brushing the teeth, or even touching the skin.
The condition results from dysfunction of the trigeminal nerve (cranial nerve V), which transmits sensory information from the face to the brain.
Although medications such as carbamazepine or oxcarbazepine are often the first line of treatment, many patients eventually develop medication-resistant trigeminal neuralgia and require procedural interventions.
Today, stereotactic radiosurgery has become one of the most widely used minimally invasive treatments for trigeminal neuralgia.
In Central America, the Centro Internacional de Cáncer (CIC) in El Salvador, led by neurosurgeon Dr. Eduardo Lovo, provides advanced treatment for trigeminal neuralgia using radiosurgery as well as other neurosurgical techniques. The center has obtained certification from the International Stereotactic Radiosurgery Society (ISRS), confirming adherence to international radiosurgery standards.
Trigeminal neuralgia (TN) is a chronic pain disorder affecting the trigeminal nerve, which is responsible for facial sensation.
The most common cause is vascular compression of the nerve near its entry into the brainstem, although other causes may include:
Typical symptoms include:
Stereotactic radiosurgery (SRS) has become a well-established treatment for trigeminal neuralgia, especially in patients who:
Radiosurgery delivers highly focused radiation to the trigeminal nerve root, typically at the root entry zone near the brainstem.
The radiation produces controlled injury to pain-transmitting fibers, interrupting abnormal pain signals.
Radiosurgery is commonly performed using Gamma Knife technology, which provides submillimeter precision in targeting the trigeminal nerve.
Although radiosurgery is an important treatment option, optimal care requires access to multiple therapeutic strategies.
The Centro Internacional de Cáncer (CIC) provides a comprehensive surgical program for trigeminal neuralgia, including:
A minimally invasive option particularly suitable for:
Microvascular decompression is a microsurgical procedure that relieves pressure on the trigeminal nerve caused by an adjacent blood vessel.
This procedure can provide long-term pain relief without damaging the nerve, making it a preferred option for selected patients.
Rhizotomy procedures intentionally disrupt pain fibers in the trigeminal nerve and may include:
These procedures can provide rapid pain relief and are often used in specific clinical situations.
The Centro Internacional de Cáncer in San Salvador has developed a specialized program for the treatment of trigeminal neuralgia and complex cranial nerve disorders.
The program led by Eduardo Lovo integrates:
Because of this expertise, the center receives patients from across Central America, including:
The International Stereotactic Radiosurgery Society (ISRS) is a global organization dedicated to advancing stereotactic radiosurgery through education, research, and quality standards.
The ISRS Center Certification Program evaluates:
The Centro Internacional de Cáncer in El Salvador has obtained ISRS certification, placing it among internationally recognized radiosurgery centers.
Yes. Many patients can be treated with stereotactic radiosurgery, which does not require an incision or craniotomy.
For patients with vascular compression, microvascular decompression may provide durable long-term relief.
Yes. The Centro Internacional de Cáncer in El Salvador, led by Eduardo Lovo, provides radiosurgery, microvascular decompression, and rhizotomy procedures for trigeminal neuralgia.
If you or a family member has been diagnosed with trigeminal neuralgia or experiences severe facial pain, you can consult the Centro Internacional de Cáncer team to explore the treatment options that may be appropriate for your case.
