The trigeminal nerve connects directly to the brain and controls facial sensations, biting and chewing. When the nerve malfunctions, people experience sudden, excruciating pain. If you suffer from trigeminal neuralgia, you may dread daily tasks: brushing your teeth, putting on makeup, even eating. Trigeminal neuralgia, also known as tic douloureux , is a chronic pain condition associated with sharp facial pain. It is most common in males but relatively rare in the general population, affecting only about 4 in , people each year. People diagnosed with trigeminal neuralgia experience intermittent shooting pain on one side of the face, coming from one or more branches of the trigeminal nerve.

Deep Brain Stimulation Treatments for Facial Pain | Pacific Facial Pain

The objective of this study is to describe the therapeutic effect and the technical and surgical problems of deep brain stimulation DBS of the posterior hypothalamus over seven years, for treatment of chronic trigeminal autonomic cephalalgias and atypical facial pain. We report a surgical series of 20 patients that underwent DBS of the posterior hypothalamus. This series includes 16 patients with chronic cluster headache CH , one patient with short-lasting unilateral neuralgiform headache attacks with conjunctival injection and tearing SUNCT and three patients with atypical facial pain. All patients of this series were resistant to any pharmacological and conservative treatment. The stimulated target was the same in the whole series even though stereotactic coordinates of the target referred to the midcommissural point differ slight in the Y anteroposterior value due to individual anatomical variability. The commissures based reference system was adapted to individual anatomical landmarks of the brainstem adding to the registration a third reference point below the commissural plane. Ten patients of this series had a complete and persistent pain-free state at 18 months follow-up and the patient with SUNCT has complete pain relief.

Trigeminal Neuralgia

The authors report promising results for a contemporary series of patients with intractable facial pain who were treated with DBS. Pain outcomes for 7 consecutive patients with unilateral, intractable facial pain undergoing DBS of the ventral posteromedial nucleus of the thalamus VPM and the periaqueductal gray PAG were retrospectively reviewed. PDI scores decreased from a mean total of SF-MPQ-2 scores decreased from a mean of 4. Notably, several patients did not experience maximum improvement until 6—9 months postoperatively, correlating with repeated programming adjustments.

For some patients, the mechanism of facial pain extends beyond the trigeminal nerve itself and originates in the deep structures of the brain. In very select patients, deep brain stimulation may be considered as a treatment option for refractory facial pain. This procedure involves insertion of electrodes into the face and pain centers of the brain, connected to a generated similar to a pacemaker to modulate these structures. This procedure is performed by Dr.
