Fig. 1From: A clinical prediction rule to identify difficult intubation in children with Robin sequence requiring mandibular distraction osteogenesis based on craniofacial CT measuresUpper airway distances D1–D11 derived from 3D reconstructions of craniofacial CBCT images acquired prior to mandibular distention osteogenesis for treatment of Robin sequence. Distances D1 to D10 are shown while D11 is the sum of D9 plus D10Back to article page
