Video-Based Facial Movement Analysis in Facial Paralysis

This study aims to evaluate facial movements in patients with facial paralysis using video-based objective analysis and to examine the relationship between these video-based measurements and standard clinical assessment scales. Participants will be asked to perform simple facial movements, such as raising the eyebrows, closing the eyes tightly, smiling, showing the teeth, pursing the lips, and puffing the cheeks, while a video recording is taken. Researchers will also evaluate participants' facial function using established clinical rating scales and questionnaires. No medication will be given, no invasive procedures will be performed, and no changes will be made to participants' current treatment. The goal is to contribute to the development of more detailed, objective, and standardized methods for evaluating facial function in patients with facial paralysis.

Inclusion Criteria: * Diagnosis of facial paralysis (e.g., Bell's palsy) * Age 18 years and older * Willing and able to provide informed consent Exclusion Criteria: * Presence of other neurological or craniofacial conditions affecting facial movement * Prior facial surgery affecting facial musculature * Inability to cooperate with video recording or clinical assessment procedures
