Lingual agenesis is a rare anomaly caused by failed embryogenesis of the lateral lingual swellings during the fourth and fifth gestational weeks. Most reported cases have been part of oromandibular limb hypogenesis syndromes. A review of the literature reveals two previously reported cases of congenital aglossia and situs inversus. A case of lingual agenesis associated with micrognathia and situs inversus is reported in a newborn presenting with upper airway obstruction at birth.
舌发育不全是一种罕见的异常情况，由妊娠第4至5周侧舌隆突胚胎发育失败引起。大多数报告病例是口下颌肢体发育不全综合征的一部分。文献回顾显示，此前有两例先天性无舌症合并内脏反位的报道。本文报告了一例舌发育不全合并小颌畸形和内脏反位的病例，该新生儿出生时即出现上呼吸道梗阻。
