Trigeminal neuralgia is a neurological condition that causes episodes of severe facial pain, similar to electric shocks that can last from seconds to several minutes. This pain affects the trigeminal nerve, which is responsible for sensation in much of the face, and can be triggered by everyday activities such as chewing, speaking, or brushing teeth. Knowing when conventional medical management should give way to surgical intervention can mean the difference between years of suffering and regaining a full life.
From our specialized practice, we treat patients who report a profound impact on their quality of life, as the fear of triggering a new episode limits basic activities and affects emotional well-being. In Costa Rica, we offer advanced surgical options for those suffering from this condition when conservative treatment fails to provide enough relief. Recognizing symptoms early and understanding available alternatives is essential to restore function and comfort.
Main Symptoms We Observe in Consultations
The most characteristic symptom is sudden, intense pain in one or more areas of the face, usually the cheek, jaw, teeth, gums, or forehead. Unlike other facial pains, this one is typically unilateral, affecting only one side of the face. Episodes may occur sporadically or in repeated bursts throughout the day.
Common triggers include light touch to the skin, exposure to cold, eating, drinking, smiling, or shaving. Some individuals experience remission periods lasting weeks or months, while in other cases the pain becomes constant and disabling. The condition may result from nerve compression by a nearby blood vessel, although some cases are linked to multiple sclerosis or other neurological injuries.
Initial Medical Treatment Options
Our initial approach is usually pharmacological. Anticonvulsant medications, particularly carbamazepine, have proven effective in controlling pain in many patients. Other drugs used include oxcarbazepine, gabapentin, baclofen, and lamotrigine, depending on individual response and side effects.
When medications fail to adequately control symptoms or produce intolerable side effects, we explore complementary options such as nerve blocks with local anesthetics or stereotactic radiosurgery—a non-invasive procedure that uses focused radiation to reduce pain transmission. However, these measures do not always offer sustained long-term relief.
When Do We Consider Trigeminal Neuralgia Surgery Necessary?
We recommend surgical intervention in the following cases:
- Pharmacological treatment does not adequately control the pain
- Medications cause severe or intolerable side effects
- The pain returns with intensity after a period of improvement
- The patient prefers a more definitive solution after years of unsuccessful conservative management
The procedure we most frequently perform is microvascular decompression, a technique aimed at separating the trigeminal nerve from the blood vessel compressing it. This approach is done through a minimal craniotomy in the posterior region of the skull, allowing access to the pontocerebellar angle where the nerve root is located.
What Does the Surgical Procedure Involve?
During microvascular decompression, we insert a small cushion of Teflon or a similar material between the nerve and the vessel compressing it, eliminating the abnormal contact. The procedure is performed under general anesthesia and usually lasts between two and three hours. Most of our patients experience immediate or shortly post-operative relief.
Other surgical techniques we consider include radiofrequency rhizotomy, glycerol injection into the Gasserian ganglion, or partial neurectomy in selected cases. The choice of procedure depends on the patient’s age, overall health, individual anatomy, and preference following a thorough evaluation.
Postoperative Recovery and Follow-Up
Recovery after microvascular decompression is typically brief. Most patients stay in the hospital between two and four days. During the first weeks, mild fatigue, slight pain at the incision site, and discomfort when chewing are common but tend to improve gradually.
We recommend avoiding strenuous physical activity, heavy lifting, and sudden head movements during the first four to six weeks. Medical follow-up is essential to monitor healing and rule out complications. Some patients may require medication adjustments during the postoperative period, gradually reducing doses as pain relief consolidates. The long-term success rate of microvascular decompression exceeds 80%.
