Feeding and mandibular distraction osteogenesis in children with Pierre Robin sequence: a case series of functional outcomes.

Introduction: In addition to upper airway obstruction, many patients with micrognathia and Pierre Robin sequence also have swallowing abnormalities and reflux. Many studies have demonstrated the effectiveness in alleviating the airway symptoms with mandibular distraction osteogenesis, but very few studies have focused on feeding and reflux outcomes.

Methods: A retrospective chart review was performed to identify patients with Pierre Robin sequence who underwent mandibular distraction osteogenesis with completed pre- and post-operative upper gastroesophageal series and videofluoroscopic swallow assessments.

Results: All six children in our series demonstrated significant improvements in both airway obstructive symptoms and feeding abnormalities. More specifically, all patients showed clinical and objective improvements in reflux and swallowing function after distraction surgery.

Conclusion: Objective and symptomatic improvements in swallowing function and reflux disease can be seen after mandibular distraction osteogenesis in children with Pierre Robin sequence.
