Prevalences of concha bullosa and nasal septum pneumatization and their relationship with nasal septum deviation in cone-beam computed tomography

Abstract

Purpose: This study was conducted to evaluate whether concha bullosa (CB) and nasal septum pneumatization (NSP) have an impact on nasal septum deviation (NSD) and to determine the prevalence of CB and NSP in a subgroup of the Turkish population in the Mediterranean region. Materials and Methods: CBCT images of 230 patients were evaluated retrospectively for the presence of CB, NSP and NSD. CB was defined as the presence of any size of pneumatization within the superior, middle, or inferior turbinate. CB laterality, NSP, NSD, age and gender were also recorded. Data analysis was performed with SPSS. Statistical significance was considered to be p < 0.05. Results: 66.5 % of the patients had at least one CB, 59.1% of the patients had NSP and 50% of the patients had NSD. While there was no significant difference between the prevalence of concha bullosa and nasal septum pneumatization and gender, there was a significant difference between the prevalence of nasal septum pneumatization and age (p = 0.026). There was no relationship between NSD and CB and NSP. Conclusion: Despite the hypothesis that CB and NSP impact NSD, this study indicates that there is no relationship between NSD and CB/NSP.
