Mandibular hypoplasia may present in isolation or in the context of glossoptosis and a U-shaped, incomplete cleft palate. This latter triad is referred to as Pierre Robin sequence. Deleterious effects of micrognathia that may present during infancy are due primarily to glossoptosis or posterior displacement of the tongue. This tongue base prolapse may cause varying degrees of upper airway obstruction. A surgical option for management of tongue base airway obstruction secondary to mandibular hypoplasia is neonatal mandibular distraction osteogenesis. Herein, the author seeks to outline the benefits and limitations of early mandibular distraction osteogenesis as a way of managing airway obstruction and feeding difficulty in newborns with micrognathia. A description of the author's operative technique as well as potential complications and pitfalls will also be discussed.
下颌骨发育不全可能单独出现,也可能与舌后坠及U形不完全腭裂同时存在。后一种三联征被称为皮埃尔·罗宾序列征。婴儿期可能出现的小颌畸形的有害影响主要是由于舌后坠或舌的后移位。这种舌根脱垂可能导致不同程度的上呼吸道梗阻。治疗下颌骨发育不全继发的舌根气道梗阻的一种手术选择是新生儿下颌骨牵张成骨术。在此,作者旨在概述早期下颌骨牵张成骨术作为治疗小颌畸形新生儿气道梗阻和喂养困难的方法的益处和局限性。还将讨论作者的手术技术以及潜在的并发症和陷阱。
