Abstract:
Congenital median cleft of the lower lip is a complete dehiscence of the skin and muscles from the lower lip to the midline of the chin，complete or partial dehiscence of the mandible，and bifurcated tongue tip，which can be embedded in the cleft of the mandible. Because the bilateral mandibular processes failed to fuse at the midline due to insufficient mesenchymal tissue development in the embryonic period，it is extremely rare. In this case，a 31 years old pregnant woman who first came to Hubei Maternal and Child Health Hospital for prenatal ultrasound screening was reported. It was found that the fetal lower lip median cleft with tongue frenulum was too short. After birth，the patient underwent surgical repair and obtained a relatively perfect surgical effect. The author analyzed the pathophysiology and ultrasonic diagnostic characteristics of this disease through the understanding of this case and combining with the previous literature，aiming to remind the ultrasonic diagnostic physicians to pay attention to the screening of the lower lip median cleft and its combined deformities，and improve the diagnostic rate.
