초록

Objective: The purpose of this study was to evaluate the effects of the mini-implant assisted rapid palatal expansion on the nasal septum and the inferior nasal meatus (INM) in the patients with nasal septal deviation. Methods: The CBCT images were taken before (T0), after (T1), and more than 5 months after (T2) MARPE in 17 patients who had NSD. According to the direction of the NSD, the concave side was set as group 1 and the convex side was set as group 2 by patient. The volume of the INM, nasal septal tortuosity ratio were calculated. Also, to evaluate 3-dimensional changes of the nasal septum, distance between C point (The junction of perpendicular plate of ethmoid bone and vomer) and three vertical planes were calcu lated. And distance between C point and lateral wall of nasal cavity was measured. Results: The total volume of the INM increased significantly after MARPE (p < 0.001). The distance from the C point to the vertical plane increased significantly after MARPE (p < 0.01). Also, there was a significant difference between the groups in the distance between the C point and the lateral wall of nasal cavity (p < 0.001) before and after treatment. But there was no significant difference in the increase ratio. Conclusion: After MARPE, the volume of INM was significantly increased. The nasal septum was more displaced to the deviated side without a significant morphological change. But the increase ratio of both group was similar.
