Cleft lip and cleft alveolus are caused by incomplete fusion of the frontonasal and maxillary prominences. However, milder forms of cleft lip are rarely accompanied by cleft alveolus. Here, we report a rare case of mini-microform cleft lip with complete cleft alveolus and cleft palate. No findings suggestive of cleft lip were evident on initial examination. However, three-dimensional facial measurements confirmed the presence of cleft lip despite no evidence of orbicularis oris muscle (OOM) rupture on ultrasonography. Collapsed nostril, as observed in this case, is usually associated with OOM rupture. However, it can also be caused by skeletal abnormalities, such as cleft alveolus. Three-dimensional facial measurements and ultrasonography can assist in accurate diagnosis when visual examination is ambiguous.
唇裂和牙槽裂是由于额鼻和上颌突起不完全融合引起的。然而，较轻的唇裂很少伴有牙槽裂。在这里，我们报告了一例罕见的微型唇裂伴完全牙槽裂和腭裂。初次检查未见提示唇裂的发现。然而，三维面部测量证实存在唇裂，尽管超声检查未见口轮匝肌 (OOM) 破裂的证据。如本例所见，塌陷的鼻孔通常与 OOM 破裂有关。然而，它也可能是由骨骼异常引起的，例如牙槽裂。当肉眼检查不明确时，三维面部测量和超声检查可以帮助准确诊断。
