Asymmetric Crying Facies Syndrome

A female infant, born vaginally at 40  weeks of gestation with a birthweight of 3260 g had an Apgar score of 10 at 1 and 5 minutes. She presented with an asymmetric facial expression when crying, with the right side of her mouth deviating inferior-laterally (Figure, A and Video [available at www.jpeds.com]). At rest, her facial expre ssion was symmetric and a thinner left lower lip was noted (Figure, B). A pediatric neurologist noted intact motor, reflex, and cranial nerve functions, and she was diagnosed with asymmetric crying facies, likely because of hypoplasia of the left depressor angularis oris muscle.
