摘要: In 69 ears with chronic otitis media and nine traumatic perforations tubal function, the size of mastoid air cell system measured planimetrically on roentgenograms functional volume filled ear spaces were studied for any correlations. The roentgenographic area also variation in duration disease. A correlation was found between abnormally small volumes impaired probably due to mucosal damage whole system, i.e. Eustachian tube, middle cells. No such association function. volume, but not area, decrease
