Choanal atresia was diagnosed radiographically using a water soluble contrast media in 2 of 7 Papio cynocephalus exposed to triamcinolone acetonide in utero. In one P. cynocephalus, the atresia was complete and was associated with other orofacial abnormalities. The other animal, previously considered to be normal, had a partial nasal obstruction. The radiographic appearance of the drug-induced defects observed in the baboon closely resemble the descriptions of spontaneously occurring defects in human infants.
