The anatomical variations of the structure of the ostiomeatal complex as the agger nasi, the uncinate process, ethmoidal bulla and the middle turbinate can be properly evaluated by the standardization of the detailed endonasal flexible fiberoptic endoscopy. AIM: The anatomical variations concerning sex, different groups of age, and the nasal cavity with variations were evaluated according to the development and pneumatization of the ethmoid bone. STUDY DESIGN: Clinical prospective. MATERIAL AND METHOD: At the current thesis, 500 patients were studied with nasal complaints (1000 middle meatus). RESULTS AND CONCLUSIONS: Extensive and bulbous-types conchas bullosas were the most frequent anatomical variation, followed by the overpneumatised agger nasi, paradoxical middle turbinate and medial angulation or medial prominence of the uncinate process. The agger nasi, extensive-type concha bullosa, paradoxical middle turbinate, medial angulation or medial prominence of the uncinate process and the overpneumatised ethmoid bulla tend to be bilateral, while the bulbous-type concha bullosa tend to be unilateral. A significant correlation between the prevalence of the overpneumatised agger nasi and the extensive and bulbous-types conchas bullosas in the same side, was observed. A significant correlation between the prevalence of extensive-type concha bullosa and bulbous-type concha bullosa in the contrary side, was observed. No significant correlation among the prevalence of the anatomical variations of the agger nasi, uncinate process, ethmoid bulla and middle turbinate was observed neither isolatedly nor associated, related to sex.
