Neuromyography in the diagnostics of Bell's palsy

After summing up the principles and technique of neuromyography, the authors illustrate their clinical application with several cases from their practice. The method is suited for monitoring the degeneration processes in Bell's palsy or other acute peripheral facial nerve pareses. The measurements permit estimating the duration of recovery and the probability of residual signs. The method helps the indication and timing of decompression surgery. In spite of certain difficulties involved in the procedure, its introduction into the diagnostics of facial nerve diseases is recommended.
