Congenital hypoplasia of the depressor anguli oris muscle is a rare mimic disorder depicted by a lower lip asymmetry apparent when laughing or crying.
A 10-year-old boy consulted our department for an asymmetry when opening his mouth. According to the family, this asymmetry was present since birth. Perinatal characteristics and childhood medical history were investigated with no abnormalities. Physical exam revealed an inability to draw down the right lower lip unilaterally. At rest position, facial asymmetry was not noticeable. Several investigations were done: A CT scan of the petrous part of the temporal bone, an MRI of soft tissues, an electromyography and a heart ultrasound. No anomalies were found.
This condition has stimulated great interest because of its potential association with congenital anomalies but also in order to reassure families often worried by the situation. A large therapeutic armamentarium is described in literature.
Among the large armamentarium of therapeutic options, we opted for a wait and see strategy through photographic smile tracking leading to an evidence of Asymmetric crying faces over time improvement.
降口角肌先天性发育不全是一种罕见的模仿性疾病，表现为哭笑时出现下唇不对称。
一名10岁男孩因张口时不对称前来我科就诊。据家属称，这种不对称自出生就存在。对围产期特征和儿童病史进行了调查，未发现异常。体格检查发现右侧下唇无法单侧下拉。在静止状态下，面部不对称不明显。进行了多项检查：颞骨岩部CT扫描、软组织MRI、肌电图和心脏超声检查。未发现异常。
由于其与先天性异常的潜在关联，也为了安抚经常为此情况担忧的家庭，这种疾病引起了极大关注。文献中描述了大量的治疗手段。
在众多治疗选择中，我们选择了通过拍照微笑跟踪观察的策略，随着时间推移，不对称哭脸现象得到改善。
