摘　　要：BACKGROUND Chronic otitis media(COM)is an inflammatory disease that lasts for a long time.It is common in developing countries.Hearing loss can result from COM.The relationship between variations in middle ear anatomy and COM was investigated in our study.AIM To compare the prevalence of middle ear anatomic variations between the cases with COM and healthy individuals.METHODS This retrospective study included 500 patients with COM and 500 healthy controls.The presence of those variants was determined:Koerner’s septum,facial canal dehiscence,high jugular bulb,jugular bulb dehiscence,jugular bulb diverticulum,sigmoid sinus anterior location and deep tympanic recesses.RESULTS A total of 1000 temporal bones were examined.The incidences of these variants were respectively(15.4%-18.6%),(38.6%-41.2%),(18.2%-4.6%),(2.6%-1.2%),(1.2%-0%),(8.6%-0%),(0%-0%).It was observed that only high jugular bulb(P<0.001)and anteriorly located sigmoid sinus frequencies(P=0.002)in the case group were statistically significantly higher than the control groups.CONCLUSION COM is a multifactorial disease and variants of middle ear have always been important in terms of potential risk for complication during surgery but rarely associated with COM as an etiology or as a consequence of the disease.We didn't find a positive correlation between COM and Koerner’s septum and facial canal defect.We ended up with a significant conclusion with the variants of dural venous sinuses-high jugular bulb,dehiscence of jugular bulb,diverticulum of jugular bulb and anteriorly located sigmoid sinus-that have been studied less and frequently associated with inner ear illnesses.
