The effects of clinical factors on airway outcomes of mandibular distraction osteogenesis in children with Pierre Robin sequence

Mandibular distraction osteogenesis (MDO) is an effective treatment for tongue-based airway obstruction in children with severe Pierre Robin sequence. An investigation was performed to determine whether certain clinical factors influence the airway outcomes of MDO. A literature search of several databases was performed to identify studies providing individual patient data. Data extracted from the studies included patient sex, age at distraction, disease type, experience of any previous surgery on the airway, length of distraction, pre- and postoperative blood oxygen saturation nadir, and osteotomy design.
