Cleft lip and palate

Prenatal ultrasound scan

Routine prenatal fetal ultrasound scanning at approximately 18 weeks' gestation can identify the possible presence of a cleft lip. In such cases of positive prenatal ultrasound, involvement of maternal-fetal specialists and genetic counseling is recommended.[37]Gagnon A, Wilson RD, Allen VM, et al; Society of Obstetricians and Gynaecologists of Canada. Evaluation of prenatally diagnosed structural congenital anomalies. J Obstet Gynaecol Can. 2009 Sep;31(9):875-81. http://www.ncbi.nlm.nih.gov/pubmed/19941713?tool=bestpractice.com In one systematic review, routine, 2-dimensional ultrasound resulted in a low prenatal detection rate of orofacial clefts in utero. However, 3-dimensional ultrasound showed accurate diagnostic accuracy for detection of prenatal cleft lip and cleft lip with or without cleft palate. Three-dimensional ultrasound did not show any increased accuracy in detecting cleft palate alone.[36]Maarse W, Bergé SJ, Pistorius L, et al.

Prenatal consultation with a cleft and craniofacial team surgeon to explain and develop the initial postnatal treatment plan enables the parents to understand and become involved in the complex, multidisciplinary management of the condition.
