Prenatal ultrasound diagnosis of Tessier number 7 cleft: Case report and review of the literature

Le résumé fourni par la source

Lateral or transverse facial clefts are the most frequent of the atypical facial clefts, classified by Tessier as no. 7 clefts. Most of the cases are diagnosed at birth, while few cases are diagnosed prenatally. We report a case of prenatal ultrasound detection and three-dimensional characterisation of a lateral facial cleft at 21 weeks of gestation, which was terminated at 22 weeks. It was a transverse cleft, running through the left cheek towards the ear, along with micrognathia and mild polyhydramnios. We also present a review on classification, anatomical features and prenatal diagnosis of Tessier no. 7 cleft.
