ABSTRACT: Background and Clinical Significance: Binder syndrome or maxillonasal dysplasia is a rare developmental disorder affecting the anterior maxilla and nasal complex, characterized by midfacial hypoplasia, a flattened nasal bridge, and increased nasofrontal angle. Case Presentation: We present a case series of seven fetuses diagnosed with Binder phenotype through targeted ultrasound examination at our prenatal diagnosis center during the SARS-CoV-2 pandemic, between September 2021 and July 2023, including the first case described in the literature before 14 weeks.
