Nevertheless, many otorhinolaryngologist-head and neck surgeons do not routinely use facial nerve electrodiagnostics. This may be due to a current lack of agreement on methodology, interpretation, validity, and clinical application. Electrophysiological analyses of the facial nerve and the mimic muscles can assist in diagnosis, assess the lesion severity, and aid in decision making. With acute facial palsy, it is a valuable tool for predicting recovery. METHODS This paper presents a guideline prepared by members of the International Head and Neck Scientific Group and of the Multidisciplinary Salivary Gland Society for use in cases of peripheral facial nerve disorders based on a systematic literature search. RESULTS Required equipment, practical implementation, and interpretation of the results of facial nerve electrodiagnostics are presented. CONCLUSION The aim of this guideline is to inform all involved parties (i.e. otorhinolaryngologist-head and neck surgeons and other medical specialists, therapeutic professionals and the affected persons) and to provide practical recommendations for the diagnostic use of facial nerve electrodiagnostics.PURPOSE Behavioral evaluation of language development is an important index for the usefulness of cochlear implantation. However, it could not apply to infants and very young children. It is useful to adopt an objective measure to examine speech discrimination in this population. Thus, the current study aimed to predict the different behavioral language performance (good versus poor) in cochlear implant (CI) recipients through the auditory cortical assessment of speech discrimination with mismatch negativity (MMN). METHODS The study comprised 40 CI children who were divided into two groups according to their behavioral language e
