Although the symptoms of maxillary sinusitis may be clinically dominant, many previous studies have showed that the origin of this disease was, in most cases, located within the anterior ethmoid region.<\/jats:p><jats:p>This study included 100 Egyptian patients, suffering from chronic maxillary sinusitis (confirmed by maxillary sinoscopy), who were subjected to \u2018systematic nasal endoscopy\u2019. It was found that all cases of chronic maxillary sinusitis were associated with anatomical variations and\/or pathological abnormalities of \u2018the ostiomeatal area\u2019. It is recommended, therefore, that during the diagnosis and treatment of chronic maxillary sinusitis, attention should be given to the region of the middle meatus and anterior ethmoid complex (or \u2018ostiomeatal area\u2019) for any anatomical variations and\/or pathological abnormalities in order to avoid recurrence of maxillary sinusitis.
