Description
Naito and colleagues reported a 2026 MRI study on severe facial pain. Trigeminal neuralgia brings short, stabbing pain attacks on one side of the face. A blood vessel pressing the nerve explains many cases, but not all. The team asked whether skull shape itself raises the risk of pain.
They measured scans from 20 patients, 20 people with facial spasm, and 16 controls. Both pain and spasm groups had a shallower back skull space than controls. The gap between key nerves ran smaller in both patient groups as well. On the painful side, nerve spacing shrank further still in the pain group. A cramped skull space may set the stage for nerve trouble. Such measures may one day flag at-risk patients before pain begins.
