About the House-Brackmann Scale

The House-Brackmann scale is a widely used clinical standard for grading the degree of facial nerve paralysis. It assesses facial symmetry and muscle function both at rest and during voluntary movements, such as smiling or closing the eyes. This system provides a consistent score from Grade I (normal function) to Grade VI (total paralysis), which is essential for tracking a patient's status over time.

Analysis Workflows

This application offers two distinct analysis workflows:

• Motion Pose Analysis: This workflow evaluates dynamic facial function by analyzing a series of six guided movements, directly following the principles of the House-Brackmann method.
• Static Pose Analysis: This workflow assesses facial symmetry from stationary images. It can perform a detailed analysis on a single photo or a trend analysis by comparing two images taken at different times (e.g., "before" and "after").

Instructions for Use

For the highest accuracy, please ensure all provided images feature a clear, well-lit, frontal facial pose with a neutral expression (unless a specific motion is requested).

• For a Single Pose Analysis: Capture or upload one image in the "Static Analysis: Single Pose" card, then click the "Process Single Pose" button.
• For a Trend Analysis: Capture or upload two images, one in "Static Pose Before" and one in "Static Pose Current". Once both are provided, click the "Process Trend Analysis" button.
• For a Motion Analysis: Capture or upload all six required poses (Neutral, Closed Eyes, etc.). Once all six images are provided, click the "Process Motion Images" button.

The results for any analysis—including annotated images and detailed measurements—will be displayed in the results area at the bottom of the page.
