The goal of this observational cross-sectional study is to investigate whether the severity of facial dysfunction is associated with psychological distress in patients with unilateral facial palsy. The main questions it aims to answer are: * Is there a significant relationship between the degree of facial muscle dysfunction (as measured by Sunnybrook Facial Grading Scale and EMG parameters) and levels of anxiety and depression (as measured by HADS)? * Does reduced facial function correlate with lower self-esteem levels (as measured by the Arabic version of the Single-Item Self-Esteem Scale)? Researcher will assess and analyze the correlation between facial motor impairment and psychological outcomes to determine whether greater functional impairment is associated with increased psychological distress. Participants will: * Undergo clinical assessment using the Sunnybrook Facial Grading Scale to evaluate facial nerve function * Receive electrophysiological evaluation using surface electromyography (sEMG) to measure muscle activity * Complete standardized questionnaires including the Hospital Anxiety and Depression Scale (HADS) and the Arabic Single-Item Self-Esteem Scale (A-SISE)
