Asymmetric crying face (ACF) means a congenital anomaly caused by either agenesis or hypoplasia of the depressor anguli oris muscle. This defect is on only one corner of the mouth since the birth, affects lower lip, and is particularly evident when the newborn is crying. Lesions at different levels of seventh nerve can cause similar and confounding weakness of the facial expressions. But, in case of ACF, forehead wrinkling, eye closure, nasolabial fold depth, and tearing are normal and symmetric functions. ACF can be either as single plain aesthetic defect or as early only index of several congenital malformations, especially of heart and genitourinary tract. Our study recognized 80 ACF cases in 11,643 newborn's population during a 34 consecutive month period: 34 on right side and 46 on left side of the mouth. ACF population presented a higher malformative risk than general population (on average 4.73% versus 3.3% of our base-line). Congenital anomalies were found more frequently associated with left ACF (3 versus 1, for a general rate of 6.52% versus 2.94%), on the same body side when anomaly was affecting pair organs. Those 3 congenital malformations were on genitourinary tract, 2 of which detected by ultrasonography. We did not find any congenital cardiac defects. According to opinion of numerous other researchers, we think ACF is not to be considered a simple aesthetic anomaly: therefore, in front of all ACF cases, a thorough search for associated anomalies should be performed.

Abstract

Asymmetric crying face (ACF) means a congenital anomaly caused by either agenesis or hypoplasia of the depressor anguli oris muscle. This defect is on only one corner of the mouth since the birth, affects lower lip, and is particularly evident when the newborn is crying. Lesions at different levels of seventh nerve can cause similar and confounding weakness of the facial expressions. But, in case of ACF, forehead wrinkling, eye closure, nasolabial fold depth, and tearing are normal and symmetric functions. ACF can be either as single plain aesthetic defect or as early only index of several congenital malformations, especially of heart and genitourinary tract. Our study recognized 80 ACF cases in 11,643 newborn's population during a 34 consecutive month period: 34 on right side and 46 on left side of the mouth. ACF population presented a higher malformative risk than general population (on average 4.73% versus 3.3% of our base-line). Congenital anomalies were found more frequently associated with left ACF (3 versus 1, for a general rate of 6.52% versus 2.94%), on the same body side when anomaly was affecting pair organs. Those 3 congenital malformations were on genitourinary tract, 2 of which detected by ultrasonography. We did not find any congenital cardiac defects. According to opinion of numerous other researchers, we think ACF is not to be considered a simple aesthetic anomaly: therefore, in front of all ACF cases, a thorough search for associated anomalies should be performed.
