Illustration of the craniofacial measurements that were found to be correlated with OSA severity. n: nasion, sn: sub-nasion, go: gonion, me: menton, cer: cervical point, ty: thyroid, np: neck point, enr: endocanthion right, enl: endocanthion left. (a) decreased upper facial height was correlated with increase in AHI, (b) increased cervicomental angle was correlated with increase in AHI, (c) increased thyromental angle was correlated with increase in AHI, (d) decreased mandibular plane angle was correlated with increase in AHI, (e) increased intercanthal width was correlated with increase in ODI for Down’s syndrome patients only.
