I had a very succesful MVD in 2000 for Trigeminal Neuralgia. Dtr slightly clipped the nerve and put teflon tape in. Recently, I experienced a migrane headache with loss of side vision for a short moment. Next day, bottom left lip (previous trigger point for tn) was completely numb, lasted 24 hours. Since then have twitch in bottom left lip when tired or stressed. Has anyone heard of complications post op from the teflon tape or clipping of nerve from MVD surgery?
