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