Abstract

OBJECTIVE: This study aims to investigate the incidence of concha bullosa (CB) subtypes according to age, sex, and the affected side.

METHODS: Paranasal sinus computed tomography (PNS CT) scans of a total of 300 patients (157 males, 143 females; mean age 34±6.4 years; range, 18 to 60 years) with CB between January 2019 and January 2020 were retrospectively analyzed. The subtypes of CB were determined and the relationship between chronic sinusitis findings, sex, and age sociodemographic features, and the affected side was evaluated.

RESULTS: The incidence of CB subtypes did not change according to age (p>0.05), while the incidence of extensive and lamellar CB was significantly higher in females than males (p<0.05). Lamellar and extensive CB were significantly higher in the right side than the left side (p<0.05). Extensive CB was observed more bilaterally than other concha subtypes.

CONCLUSION: Concha bullosa subtypes and their incidences may vary according to sex, age, and side on which they are seen.
