Nasal airway obstruction: CT assessment.
Twenty-one cases of nasal airway obstruction were analyzed using computed tomography (CT) at the Children's Hospital in Boston between 1980 and 1984. Seven of these patients had stenosis of the entire nasal passage, two had stenosis of the anterior nasal cavity, and 12 had atresia of the posterior choanae. The spectrum of these abnormalities and the optimum technique for CT scanning are discussed.
