Semon's law
Semon's law states that in a progressive lesion of the recurrent laryngeal nerve, the abductors are paralysed before the adductors.
This means that in an incomplete paralysis, the cord will be brought to the midline by the adductors, but in complete paralysis it falls away to the paramedian position.
