An asymmetrical crying facies due to hypoplasia or absence of the depressor anguli oris muscle (DAOM) was observed in 23 infants and children. The cases were divided into two groups. Group 1 consisted of 12 patients who had associated cardiac abnormalities. In group 2 were 11 patients who either had other non-cardiac abnormalities (6) or no other abnormalities (5). The associated cardiac anomalies recorded in the literature are reviewed and 2 infants in this series are reported with abnormalities not previously described. The results of chromosomal analysis have generally been found to be normal, although a patient in our series was found to have trisomy E (18). The incidence of hypoplasia of the DAOM in newborn infants in a maternity hospital hospital is assessed and was found to be lower than reported in other studies. It is concluded that a detailed and careful examination for congenital abnormalities should be carried out on every child with an asymmetrical crying facies.
在23例婴幼儿中观察到因口角降肌发育不全或缺失导致的不对称哭脸。病例分为两组。第1组包括12例伴有心脏异常的患者。第2组有11例患者，他们要么有其他非心脏异常（6例），要么没有其他异常（5例）。本文回顾了文献中记录的相关心脏异常情况，并报告了本系列中有2例婴儿存在以前未描述过的异常情况。虽然本系列中有1例患者被发现有E三体（18），但一般发现染色体分析结果正常。评估了一家妇产医院新生儿口角降肌发育不全的发生率，发现其低于其他研究报告的发生率。得出的结论是，应对每例有不对称哭脸的儿童进行详细、仔细的先天性异常检查。
