Some sinonasal microanatomic variations can leads to chronic sinusitis. These variations are most commonly in middle meatus and narrow the ostiumeatal unit. In this study, we compared microanatomic variations of lateral nasal wall and sinuses between normal cadavers and patients with chronic sinusitis. This comparative-descriptive study was conducted between 50 sinonasal complexes. The results demonstrated higher prevalence of concha bullosa, medialized uncinate process, enlarged ethmoid bulla, S shape septal deviation and accessory ostium of maxillary sinus in chronic sinusitis patients. Onodi cells were more prevalent in cadavers. In conclusion, we considered “these anatomical variations are predisposing factors for chronic sinusitis
