Pseudoprognathism—An auxiliary ultrasonographic sign for transvaginal ultrasonographic diagnosis of cleft lip and palate in the early second trimester

Cleft lip and palate have been diagnosed antenatally only in the late midtrimester or at later gestational ages, when it is too late for pregnancy termination. The diagnosis of fetal cleft lip was made in three low-risk nulligravid women at 14 to 16 weeks of gestation by systematic screening with a 6.5 MHz transvaginal transducer and was confirmed by postabortal examination.
