The House-Brackmann Scale is the most commonly used tool for the clinical evaluation of facial nerve function. The scale is based upon functional impairment, ranging between I (normal) and VI (no movement). This classification system was first described in 1985 by Dr John W. House and Dr Derald E.

Intended Population
[edit | edit source]
The scale is used to determine the severity of facial nerve dysfunction in people with facial palsy.
Method of Use[edit | edit source]
The score is determined by measuring:
- the upwards movement of the midportion of the top of the eyebrow, and
- the outwards movement of the oral commissure
For both the eyebrow and oral commisure movement, 1 point is assigned for every 0.25 cm motion up to a maximum of 1cm. The scores for each structure are added together to give the House-Brackmann score. The maximum score obtainable is 8, if both structures move the full 1cm.Cite error: Invalid <ref> tag; name cannot be a simple integer. Use a descriptive title
For objectivity, measurements should be made on both the normal and the affected side.Cite error: Invalid <ref> tag; name cannot be a simple integer. Use a descriptive title
