The psychological and psychosocial effects of facial paralysis: A review.

Facial nerve function is essential for a multitude of processes in the face, including facial movement; expression; and functions, such as eating, smiling, and blinking. When facial nerve function is disrupted, facial paralysis may occur and various complications for the patient may result. Much research has been conducted on the physical diagnosis, management, and treatment of facial paralysis. However, there is a lack of knowledge of the psychological and social effects of the condition. Patients may be at an increased risk for anxiety and depression, as well as negative self and social perceptions. This review analyzes the current literature on the various adverse psychological and psychosocial effects of facial paralysis, factors that may play a role, and treatment options that may help improve patients' quality of life.
