Pierre Robin sequence (PRS), also referred to as Robin sequence, is defined by micrognathia, glossoptosis, and upper airway obstruction and results in varying degrees of airway compromise after birth. 1,2 Both evaluation and treatment of airway obstruction in infants with PRS varies between centers with considerable controversy around the role of polysomnography for the diagnosis of sleep-related breathing disorders and assessment of treatment response. 3,4 Disagreements about the role of polysomnography are undoubtedly influenced by access to polysomnographic testing as this is limited or unavailable in many areas. 5,6 On the treatment side, there are differences between centers with respect to available treatment options and how treatment success is evaluated. While there has been considerably more study of the surgical options compared to nonsurgical options, the field overall is hampered by a relative paucity of high quality evidence. 7 There is a relatively long list of options for management of airway obstruction in infants with PRS. Nonsurgical options include prone sleep position, 8 supplemental oxygen, use of an oral appliance with a velar extension, 9 oropharyngeal or nasopharyngeal tube, noninvasive ventilation (typically continuous positive airway pressure), and placement of an endotracheal tube. 3 Surgical options include tongue-lip adhesion (or glossopexy), mandibular distraction osteogenesis, subperiosteal release of the floor of the mouth, and tracheostomy-with additional surgical options used more selectively. 3 There are multiple algorithms from different centers to support treatment decisions but none incorporate all treatment options and all use different strategies for decision making. 3,10,11 With few studies comparing treatment modalities and even fewer randomized trials, there is little information on the characteristics of infants that will best respond to any given therapy. 7,11 The study by Ehsan and colleagues in this issue of the Journal of Clinical Sleep Medicine 12 adds another option, watchful waiting, to this list. The study reports on a cohort on infants with PRS who were treated with conservative (ie, nonsurgical) management. 12 The study design was a 14-year retrospective cohort study that included infants with PRS who underwent polysomnography COMMENTARY Understanding the Spectrum of Treatment Options for Infants With Pierre Robin Sequence and Airway Obstruction Commentary on Ehsan et al.
