Craniofacial microsomia (CFM) is a common craniofacial anomaly characterized by asymmetric malformation of the mandible, ear, and other structures including the upper airway. The degree of mandibular hypoplasia is classified using a scheme developed by Pruzansky and modified by Kaban. Severe condylar dysplasia is the hallmark of Pruzansky-Kaban types IIB and III. Distraction osteogenesis has emerged as a treatment modality for mandibular hypoplasia in this setting for the treatment of asymmetry and airway obstruction. However, its use to resolve upper airway obstruction and avoid tracheostomy in infants with types IIB and III is not reported in the literature. The authors present a patient with successful distraction osteogenesis in a patient with CFM resulting in a Pruzansky IIB micrognathia. The authors achieved resolution of upper airway obstruction and avoidance of tracheostomy.
颅面短小畸形(CFM)是一种常见的颅面畸形,其特征为下颌骨、耳朵以及包括上呼吸道在内的其他结构出现不对称畸形。下颌骨发育不全的程度采用由普鲁赞斯基制定并经卡班修改的方案进行分类。严重的髁突发育异常是普鲁赞斯基 - 卡班IIB型和III型的标志。在这种情况下,牵引成骨已成为治疗下颌骨发育不全以纠正不对称和气道阻塞的一种治疗方式。然而,文献中未报道其用于解决IIB型和III型婴儿的上呼吸道阻塞及避免气管切开术的情况。作者报告了1例成功采用牵引成骨治疗CFM导致普鲁赞斯基IIB型小颌畸形的患者。作者实现了上呼吸道阻塞的解决并避免了气管切开术。
