↵a The occurrence of BT relative to turbinate size shows that BT did not primarily occur in the smaller turbinate when size asymmetry was present. Patients who had a BT on 1 scan often did not always have a BT on a prior exam. Nasal cycling indicates a change in nasal turbinate symmetry between the index and prior study. This occurred relatively infrequently.
