Micrognathia-Retrognathia Clinical Pathway — N/IICU and ICU
Mandibular Distraction Osteogenesis Candidate
Mandibular distraction osteogenesis (MDO) is a jaw surgery that treats sleep apnea and enhances airway function by widening the mandible (lower jaw). The basis of mandibular distraction is a surgical technique commonly associated with orthognathic surgery. It is the surgical technique of generating new bone by progressive stretching of divided segments. Most commonly, mandibular distraction is used to treat children and adults with jaw abnormalities, especially due to cleft palate, severe asymmetry, and severe mandibular hypoplasia with resulting airway compromise, facial clefts, Treacher Collins syndrome, Pierre Robin Sequence, and hemifacial macrosomia.
