Trigeminal neuralgia (also called tic douloureux) is sometimes a symptom of multiple sclerosis and is often extremely painful. It tends to come and go unpredictably in sudden shock-like attacks that usually affect one side of the face.
Initial treatment is with drugs and people are often advised to avoid any triggers that set the pain off. Sometimes surgery is used if drugs do not work. However, surgery can leave the face feeling numb because it works by damaging the trigeminal nerve in the face.
This study looked at a particular kind of surgery called percutaneous balloon compression (PBC). A needle is inserted under local anaesthetic and a small balloon is used to compress the nerve. The resulting damage stops the electrical activity in the nerve which reduces or stops the pain.
The cases of 21 people with MS who had already received PBC for trigeminal neuralgia were reviewed. All had either an excellent or a good outcome with a single or repeated procedure. The factors which helped most were having only one branch of the trigeminal nerve affected, not having had previous surgery and using a short compression time and/or a pear-shaped balloon during the procedure.
The researchers concluded that PBC is a safe and effective treatment for trigeminal neuralgia when drug treatments have not worked.
