The Importance and Psychology of Facial Expression.

Facial expression is of critical importance in interpersonal interactions. Thus, patients with impaired facial expression due to facial paralysis experience impaired social interactions. Numerous studies have shown that patients with facial paralysis and impaired facial expression suffer social consequences as demonstrated by being rated negatively with regards to attractiveness, affect display, and other traits. This has been demonstrated subjectively and objectively. Fortunately, reconstructive surgeries that restore the ability to express emotion can restore normalcy in these patients.
