Abstract

Background and Objectives
The purpose of this study was to investigate the prevalence of incidental paranasal sinus (PNS) opacification in nasal septal deviation (NSD) using computed tomography (CT) and to identify contributing factors.
Subjects and Method
We analyzed 216 patients who underwent septoplasty for the correction of NSD and who underwent preoperative PNS CT. We assessed the prevalence of incidental PNS opacification in these patients and determined the type of NSD according to Mladina classification. We also evaluated whether the direction of NSD affected the presence of PNS opacification on CT, and whether the presence of PNS opacification was associated with other rhinologic symptoms.
Results
Of 216 patients with NSD, 86 showed opacified PNS on CT. According to Mladina classification, NSD patients were classified as type I (24.1%), type II (36.1%), type III (20.8%), type IV (5.6%), type V (9.7%), type VI (2.3%), or type VII (1.4%). Patients with type II NSD showed a significantly higher incidence of PNS opacification compared with other types of NSD (p=0.001). However, the direction of NSD did not significantly influence the presence of incidental PNS opacification. Furthermore, regardless of the presence of PNS opacification, there was no significant difference in rhinologic symptoms such as olfactory dysfunction, among others.
Conclusion
We found that incidental PNS opacification on CT was common in NSD patients, especially in patients with type II NSD. Thus, we suggest that CT evaluation of patients with NSD may be helpful for assessing comorbid PNS pathologies as well as objectively identifying nasal septal deformities.
