The<unk>  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. The score predicts recovery in those with Bell's palsy. The score carries the name of the Dr John W.<unk>  and Dr Derald E.<unk> , otolaryngologists in Los Angeles, California, who first described the system in 1985. It is one of a number of facial nerve scoring systems, such as Burres-Fisch, Nottingham, Sunnybrook, and Yanagihara. Of these, the Nottingham scale has been identified as possibly being easier and more reproducible. A modification of the original<unk> , called the "Facial Nerve Grading Scale 2.0" (FNGS2.0) was proposed in 2009.
