Drs Munin and Rosen have raised some concerns concerning (1) our classification of neural damage, (2) our definitions of electrophysiologic findings, and (3) our way of grouping subsets for statistical analysis. There is no doubt that Seddon's1 classification system is less than perfect for LEMG. Hopefully, every laryngeal electromyographer is aware of the restrictions that Drs Munin and Rosen describe. However, to classify electrophysiologic findings according to Seddon in order to describe a diagnosis has been clinical routine for years in many centers. Our goal was to test the reliability of this approach using the current standard of practice, since data concerning the prognostic value of LEMG have been lacking so far.
