Management of Airway Obstruction in Infants With Pierre Robin Sequence

Abstract

Background:. Pierre Robin sequence (PRS)-related airway obstruction is often treated surgically; however, objective measures predicting the need for surgery are poorly defined. Methods:. A retrospective chart review was performed on 171 neonates with PRS. Infants were grouped based upon intervention modality: nonsurgical (conservative) or surgical [mandibular distraction osteogenesis (MDO) or tracheostomy]. Demographic data, physical examination findings, and study results were compared between groups to determine risk factors for surgical intervention, and to predict long-term success or failure of those interventions. Results:. The most significant, objective risk factor among those receiving surgery was a poor preintervention sleep study [obstructive index (OI): 42.4 versus 12.9 for the conservative treatment group; P 20, whereas 67.5% of those treated surgically met this severity measure. Of those receiving surgery, tracheostomy was associated with neurologic impairment (P = 0.030) and low birth weight (P = 0.046) compared with the MDO group. Together with syndromic status, these risk factors were useful for predicting failure of MDO to avoid subsequent tracheostomy (test sensitivity and specificity were 64.2% and 100.0%, respectively). No long-term differences in speech or micrognathia were detected between the 3 groups; however, those treated conservatively or with MDO had improved long-term feeding and airway obstruction outcomes compared with the tracheostomy group. Conclusions:. Surgical intervention for PRS-related tongue-based airway obstruction should be strongly considered with an OI >20. Tracheostomy should be reserved for complex patients with concomitant syndromic diagnosis, neurologic impairment, and low birth weight.
