[The condition of the middle ear mucosa in chemodectoma of the tympanic glomus at the early stage of the disease]. / Sostoianie slizistoi obolochki srednego ukha pri khemodektome barabannogo glumusa na rannikh étapakh razvitiia opukholevogo protsessa.

28 samples of tissue from the middle ear obtained at removal of chemodectoma were studied histologically. Investigation of the tympanic cavity mucosa has shown correlation between the severity of fibroatrophic changes in the middle ear mucosa and duration of the disease. Pathomorphological alterations in the middle ear mucosa at early stages of chemodectoma (stage I and II) are similar to those in chronic lingering mucositis.
