House Brackmann Scale

The House-Brackmann Scale assesses the severity of facial nerve dysfunction, particularly in conditions such as facial palsy, Bell’s palsy, and post-surgical nerve recovery. It provides a standardized grading system from Grade I (normal function) to Grade VI (total paralysis) to evaluate facial movement, symmetry, and voluntary muscle control. This scale helps clinicians monitor progress and determine appropriate treatment strategies.

The House-Brackmann grading system is the most widely used scale for evaluating Bell’s palsy, as it accurately assesses facial nerve paralysis. It categorizes the severity of facial dysfunction, allowing healthcare providers to track recovery and adjust treatment plans accordingly. Other facial grading systems exist, but the House-Brackmann Scale remains the clinical standard.

The House-Brackmann score for facial nerve weakness ranges from Grade II to Grade V, depending on the severity of movement impairment. Mild weakness (Grade II) includes slight asymmetry and near-normal function, while moderate to severe dysfunction (Grades III to V) involves increasing difficulty with voluntary movement and incomplete eye closure. Total paralysis (Grade VI) represents the most severe form, with no facial motion present.
