When and who made the first report on oromandibular dystonia?
I think the following literature is the first, but does anyone know any other literature?
Romberg M.H. Krampf im Muskelgebiete der Pars minor Quinti. Masticatorischer Gesichtskrampf. Trismus. In: Lehrbuch der Nervenkaranheiten des Menschen, Alexander Duncker, Berlin, 308-316. 1846.
