At a glance
What it is
A radiofrequency lesion is created at the Gasserian ganglion in Meckel's Cave to interrupt the trigeminal nerve branch responsible for facial pain.
Who it is for
Patients with trigeminal neuralgia, particularly those for whom surgery or general anaesthesia carries too much risk.
What to expect
A fine needle is inserted through the cheek under local anaesthesia and X-ray guidance. Nerve stimulation confirms the correct branch before ablation, minimising post-procedure numbness.
Radiofrequency for trigeminal neuralgia at Alimran Medical Center
The Gasserian ganglion — the main sensory ganglion of the trigeminal nerve — sits in Meckel's Cave at the base of the skull. A partial radiofrequency ablation of this ganglion can effectively interrupt the pain pathway responsible for trigeminal neuralgia.
The procedure is performed under local anaesthesia. A small, thin needle is inserted through the middle of the cheek and gently guided with X-ray assistance through the foramen ovale into Meckel's Cave where the ganglion sits. Before the ablation is performed, electrical stimulation is used to confirm precisely which branch of the trigeminal nerve is involved in the pain. This important step ensures that only the affected branch is treated, avoiding excessive post-procedure numbness.
For patients where surgery and general anaesthesia are too risky — due to advanced age or medical comorbidities — this injection technique offers effective and durable pain relief with a favourable safety profile.
