Cephalometric radiographs, nasal airway resistance, and the effect of adenoidectomy.

Cephalometric radiographs and nasal airway resistance values of 67 children were compared--correlation between each of several measurements of the postnasal airway and airway resistance from anterior nares to oropharynx was poor. At the 5% level of significance, the averaged shortest distance between the anterior face of the adenoid mass and the posterior wall of the antrum was related to be averaged airway resistance of the 67 subjects. Nasal airway resistance measurements in 22 children prior to and following adenoidectomy established that nasal airway resistance was reduced following adenoidectomy.
