[Emotional impact of facial palsy].

Facial palsy is not only a movement disorder but leads also to an emotional and communicative disorder in chronic stage but also in some patients already during the acute phase of the disease. The present review describes the current knowledge of the neurobiological and psychological fundamentals on the relation of facial movement and its emotional context. So far there is not much knowledge on the impact of a facial palsy on the interaction between facial movement, emotional processing and communicative skills of the patient. The emotional contagion seems to be reduced in patients with facial palsy. The ability to express emotions seems also to be reduced. Moreover, the patients feel to be perceived negatively. In fact, most of the expressions of patients with facial palsy are allocated with a negative affect even when the patients are smiling. Patients with facial palsy react with negative stress, anxiety and depression. The patients avoid social contacts. In turn, this reinforces the communicative disorder. The otorhinolaryngologist can use the Facial Disability Index as a simple questionnaire to detect such dysfunctions. Diagnostics that are necessary to develop a therapy program are presented in this review. Standardized therapy concepts that are not only treat the movement disorder but also the emotional context is missing so far. Finally, the review will give an outlook on potential therapy strategies. © Georg Thieme Verlag KG Stuttgart · New York.
