For the dysmorphic features he underwent cranial x-ray showing increased biparietal diameter with reference to frontal bossing, look to mask harlequin orbits characterized by increased density and thickness of the orbital roofs (Figure 1).
Pulse Oximetry tracings before CPAP (upper) shows basal SpO2 of 93%, SpO2 nadir of 65%, repetitive dips in oxygen saturation to < 90%; oxygen desaturation index (ODI) of 23.4/h. Pulse oximetry normalized with nocturnal CPAP treatment (below) in a child with severe obstructive sleep apnea and osteopetrosis with renal tubular acidosis.
