Prenatal measurement of micrognathia and oropharyngeal space in patients with Robin sequence

Micrognathia is the initiating feature of Robin sequence (RS) and leads to airway obstruction. Prenatal identification of micrognathia is currently qualitative and has not correlated with postnatal findings in previous studies. Oropharyngeal airway space has not been evaluated prenatally. The purposes of this study were to: (1) quantitate mandibular characteristics and oropharyngeal size on prenatal magnetic resonance imaging (MRI) and (2) identify differences in fetuses with postnatal RS compared to those with micrognathia (without RS) and normal controls.
