House–Brackmann score
Purposemeasure degree of damage in facial nerve palsy

The House–Brackmann score is a score to grade the degree of nerve damage in a facial nerve palsy. The measurement is determined by measuring the upwards (superior) movement of the mid-portion of the top of the eyebrow, and the outwards (lateral) movement of the angle of the mouth. Each reference point scores 1 point for each 0.25 cm movement, up to a maximum of 1 cm. The scores are then added together, to give a number out of 8.[1] The score predicts recovery in those with Bell's palsy.[2]

The score carries the name of the Dr John W. House and Dr Derald E. Brackmann, otolaryngologists in Los Angeles, California, who first described the system in 1985.[1] It is one of a number of facial nerve scoring systems, such as Burres-Fisch, Nottingham, Sunnybrook,[3] and Yanagihara.[4] Of these, the Nottingham scale has been identified as possibly being easier and more reproducible.[3] A modification of the original House–Brackmann score, called the "Facial Nerve Grading Scale 2.0" (FNGS2.0) was proposed in 2009.[4]

Grade Description Measurement Function % Estimated function %
I Normal 8/8 100 100
II Slight 7/8 76–99 80
III Moderate 5/8–6/8 51–75 60
IV Moderately severe 3/8–4/8 26–50 40
V Severe 1/8–2/8 1–25 20
VI Total 0/8 0 0
