Background: Facial filler is emerging as a nonsurgical alternative for addressing static asymmetry in facial paralysis (FP).

Objectives: To elucidate the patient experience for facial filler and to facilitate preprocedure counseling and education.

Materials and Methods: Patients receiving hyaluronic acid filler for FP at a tertiary academic medical center were prospectively recruited.

Primary outcomes included patient-reported pain, facial symmetry (on a visual analog scale), and the results of quality-of-life surveys (FACE-Q satisfaction with facial appearance [SFA], FACE-Q psychosocial distress [PSD], Patient Health Questionnaire-9 [PHQ-9], and Euro Quality of Life 5-Dimension [EQ5D]) preprocedure and at 1 and 14 days postprocedure.
