The role of septated concha bullosa on sinonasal pathologies.

The purpose of this study was to retrospectively determine the possible role of septated concha bullosa on sinonasal pathologies. Paranasal sinus computerized tomography scans of patients with symptoms of headache, postnasal drip, nasal obstruction and smell disorders were retrospectively evaluated. Twenty-eight subjects with unilateral septated concha bullosa and 13 subjects with unilateral concha bullosa without septation were selected as the study and control groups, respectively. Both groups were compared according to the presence of septal deviation and sinus pathology. There were no statistically significant differences in baseline characteristics (age and gender) between the groups. Sinus involvement was found in 20 patients (71.4 %) in the study group and in 10 patients (76.9 %) in the control group. The most common pathology accompanying septated concha bullosa was maxillary sinusitis (65 %), and ethmoid sinus was the second most involved sinus (25 %). Similar results in terms of sinus involvement were also seen in the control group. Septal deviation was seen in 18 patients in the study group (64.2 %) and in 12 patients in the control group (92.3 %). Eventually, there was no statistically significant difference between septated and non-septated concha bullosa groups according to the accompanying sinonasal pathologies.
