Background: Concha bullosa (CB) is the most prevalent anatomical variant in the osteo-meatal complex. Middle Easterners have a disproportionately high incidence of nasal septal deviation (NSD). Objectives: To determine if concha bullosa increases the risk of developing rhinosinusitis and NSD. Subjects and Methods: Thirty people who were diagnosed with chronic rhinosinusitis at the ENT Outpatient Clinic at Zagazig University Hospitals participated in this prospective study. All subjects undergone full clinical evaluation as well as Computerized tomography study on the nose and paranasal sinuses. Results: None of the groups differed significantly in terms of the quantity or location of NSD, and between 88% and 12% of the patients with CB, the air channel was either intact or completely obliterated. About 96% of the patients with NSD had preserved air channel and 4% of them had obliterated air channel. Conclusion: CT-imaged concha bullosa, regardless of its size or shape, does not increase the likelihood of sinusitis or NSD.
