Evaluating the frequency of anatomical variations of the sinonasal region in pediatric and adult age groups according to gender: computed tomography findings of 1532 cases

Abstract Background The aim of the present study was to evaluate retrospectively frequency anatomical variations in sinonasal region, which were frequently seen our cases, for whom coronal section paranasal computed tomography imaging (CPNCT) taken, as well correlation these with age and gender correlations identified one another. In study, CBCT scans a total 1532 (825 males 707 females) cases evaluated order determine prevalence nasal cavity sinuses. All images taken by multi-detector CT device (Aquilion, Toshiba medical system, Tokyo, Japan). Results Most detected three septum deviation (79.7%), concha bullosa (40.9%), ethmoid bulla (21.0%) according order. When gender, deviation, bullosa, anterior clinoid process pneumatization more observed Onodi cell females ( p < 0.05). relationships another evaluated, it found that possibility presence Haller higher terms taking independent variable, statistically significant difference pterygoid pneumatization, cell, pneumatized crista galli, bulla, paradoxical middle between adult children groups Conclusion occurrence various region variations, differences both genders groups. each other also remarkable. Consequently, is believed comprehensive studies serious objective evaluations evaluating change besides their are required.
