The Bortnick Miller apparatus: a useful alternative to impedance audiometer for assessment of eustachian tube function in chronic suppurative otitis media

Abstract

Eustachian tube function was assessed by impedance audiometer and Bortnick Miller apparatus in 60 ears with central perforation in pars tensa. Result of both the instruments were compared and presented.

Evaluation of Mucocilliary Function of Eustachian Tube in Children with Chronic Otitis Media Mucosal Type

“…The simpler methods, which are available, are non-physiological and more or less quantitative, indicating anatomical patency of the tube, which does not necessarily mean normal function. 26 We used 4% lidocaine in nasal pack so that if nasopharyngoscopy need to be done there wont be much discomfort to the child. Both lidocaine and preservative methylparaben cause cilliostasis, 27 but the effect should not be significant as we made the child to lie down in lateral position with testing ear uppermost.…”
