Background: Data on structural modifications caused by septal deviation may help otolaryngologists make informed decisions on the inclusion of turbinate surgery with septoplasty as well as identify the part of the inferior turbinate that requires more attention during surgery.
Objective: This study aimed to compare the dimensions of the ipsilateral and contralateral sides of the inferior turbinate and the septal deviation in a Korean population.
Methods: We retrospectively analyzed the facial computed tomography (CT) scans of 111 patients who underwent septoplasty between January 2012 and December 2017 for the anterior, posterior, and maximally deviated sites of the inferior turbinate.
Results: Statistical analyses revealed differences in the medial mucosa and the total thickness of the anterior and maximally deviated sites between the ipsilateral and contralateral sides. The medial mucosal portion of the anterior site was 4.64±2.12 mm on the contralateral side and 4.14±1.75 mm on the ipsilateral side (p=0.03). The total thickness of the anterior site was 9.72±4.25 mm on the contralateral side and 8.58±3.36 mm on the ipsilateral side (p=0.02). The medial mucosal portion of the maximally deviated site was 5.09±2.52 mm on the contralateral side and 4.39±2.05 mm on the ipsilateral side (p=0.04). The total thickness of the maximally deviated site was 9.58±4.06 mm on the contralateral side and 8.81±3.50 mm on the ipsilateral side (p=0.04). No significant differences were found in the measurements between the two sides of the posterior site or in the bone thickness at any of the sites. The inferior turbinate did not show any significant relationship with the deviation angle.
Conclusion: A conservative submucosal turbinoplasty without bone removal may be favorable.
Level of Evidence: Level IV

Fig. 1.Measurement of the inferior turbinate at different sites. (A) The thicknesses of the lateral mucosa (a), bony portion (b), and medial mucosa (c) of the inferior turbinate were measured. (B) The anterior site of the inferior turbinate was measured at the level of the second cut of the middle turbinate using coronal computed tomography. (C) Measurement of the inferior turbinates at the maximally deviated site showed bone thickness at the maximally deviated site. (D) The posterior site of the inferior turbinate was measured immediately before the end of the bony portion of the inferior turbinate.
