  • Title: Foetal facial clefts: prenatal evaluation of lip and primary palate by 2D and 3D ultrasound.
    Author: Mittermayer C, Blaicher W, Brugger PC, Bernaschek G, Lee A.
    Journal: Ultraschall Med; 2004 Apr; 25(2):120-5. PubMed ID: 15085453.
    Abstract:
    INTRODUCTION: To examine whether three-dimensional ultrasound (3D US) is an accurate diagnostic method of clinical use in the ability to define the location and extent of facial clefting prenatally, compared to two-dimensional ultrasound (2D US). METHODS: 18 foetuses suspected or diagnosed to suffer from a facial cleft by 2D US were examined with a targeted 3D US. 2D US and 3D US results were compared with postnatal outcome. RESULTS: Comparison of the number of foetuses with a cleft lip + primary palate diagnosed correctly with 2D US with the results of adjunctive 3D US (true positive + true negative) showed that adjunctive 3D US correctly diagnosed more cleft lips (100 %; 15/15 foetuses vs. 66 %; 12/18 foetuses) and more cleft primary palates (100 %; 12/12 foetuses vs. 58 %; 7/12 foetuses). CONCLUSION: Interactive review of standardised 3D multiplanar images allows to systematically evaluate lip defects and abnormalities of the maxillary tooth-bearing alveolar ridge. The accuracy of adjunctive 3D ultrasound is superior to 2D ultrasound alone for extensive prenatal diagnosis of cleft lip with or without cleft primary palate.
