| Abstract: | A comparative assessment of ventilatory function of Eustachian Tube was done in 50 cases having perforated tympanic membranes with the help of simple Bortnick-Miller apparatus and sophisticated Impedance Bridge. A highly significant correlation was obtained between these two tests. This proved the reliability of simple Bortnick-Miller Apparatus. |
