House-Brackmann Classification of Facial Function�
Grade | Characteristics |
I. Normal | Normal facial function in all areas |
II. Mild dysfunction | GrossSlight weakness noticeable on close inspection May have slight synkinesis At rest, normal symmetry and tone MotionForehead – Moderate to good function Eye – Complete closure with minimal effort Mouth – Slight asymmetry |
III. Moderate dysfunction | GrossObvious but not disfiguring difference between sides Noticeable (but not severe) synkinesis, contracture, or hemifacial spasm At rest, normal symmetry and tone MotionForehead – Slight to moderate movement Eye – Complete closure with effort Mouth – Slightly weak with maximum effort |
IV. Moderately severe dysfunction | GrossObvious weakness and/or disfiguring asymmetry At rest, normal symmetry and tone MotionForehead – None Eye – Incomplete closure Mouth – Asymmetrical with maximum effort |
V. Severe dysfunction | GrossOnly barely perceptible motion At rest, asymmetry MotionForehead – None Eye – Incomplete closure Mouth – Slight movement |
VI. Total paralysis | No movement |

House-Brackmann Classification of Facial Function
The House-Brackmann Facial Nerve Grading System is widely used to characterize the degree of facial paralysis. In this scale, grade I is assigned to normal function, and grade VI represents complete paralysis. Intermediate grades vary according to function at rest and with effort.
