Evaluation of inferior turbinate hypertrophy in patients with congenital and traumatic nasal septum deviation

Abstract

To compare mucosal and bony measurements in patients with congenital and traumatic nasal septum deviation and compensatory inferior turbinate hypertrophy. The study examined 50 patients with nasal septum deviation (25 congenital and 25 traumatic) and compensatory inferior turbinate hypertrophy in the contralateral nasal cavity, confirmed by computed tomography. The study compared inferior turbinate measurements on the concave and convex sides of the septum, in the congenital and traumatic groups. MEASUREMENTS COMPRISED: the shortest distance from the median line to the medial border of the conchal bone; the distances from the most medial part of the conchal mucosa and the conchal bone to the lateral line; the projection angle of the inferior turbinate; and the widest parts of the whole inferior turbinate and the inferior turbinate conchal bone. The differences between the concave and convex side measurements were compared in the congenital group versus the traumatic group; for three measurements, the difference between these two groups was statistically significant (p < 0.05). The present study findings suggest that the conchal bone has a marked influence on nasal patency in patients with congenital septal deviation. These findings supported the decision to excise the inferior turbinate bone at the time of septoplasty, especially when treating congenital septal deviation.
