The Effect of Mandibular Distraction Osteogenesis on Weight Velocity in Infants With Severe Pierre Robin Syndrome

Mandibular distraction osteogenesis (MDO) effectively improves airway obstruction in Pierre Robin syndrome (PRS) patients. However, whether or not early MDO is beneficial to the development of children is still controversial. To observe the influence of PRS patient age at the time of MDO on their development, the authors retrospectively analyzed preoperative and postoperative body weight in 41 children with PRS who underwent MDO treatment from 2014 to 2016. The body weight of the infants at the time of birth, first visit, MDO surgery, distractor removal, and palatoplasty surgery was recorded. The body weight percentile significantly fell from 34.4 ± 5.8 at birth to 13.1 ± 3.6 at the time of MDO (P
