The technique used for TEMMA — middle meningeal artery (MMA) embolization — has been performed thousands of times worldwide for other conditions, most commonly chronic subdural hematomas (collections of blood between the brain and its outer covering). Across all those procedures, the safety record has been excellent.
For migraine treatment specifically, early studies have shown a strong safety profile with no major neurologic complications reported in published case series.
Platinum coils like the one used in TEMMA are a standard, well-understood tool in neurovascular medicine. They have been used millions of times worldwide to treat aneurysms and other vascular conditions.
The middle meningeal artery supplies the dura — the thick covering around the brain — not brain tissue itself. Closing it does not affect how the brain works, your thinking, or your memory.
TEMMA is performed by neurointerventional specialists who have completed medical school, residency, and an additional 2–3 year fellowship focused entirely on minimally invasive cerebrovascular procedures.
The procedure is done through a 2–3 mm opening at the wrist or groin — closed with a small bandage. No head incisions, no skull opening, no surgical wound.
Most patients go home the same day and feel normal within 24 hours. There is no hospital stay and no prolonged recovery period.
Studies of MMA embolization — for migraine and other conditions — consistently show no loss of brain function, no cognitive changes, and extremely low rates of serious complications.
