Diagnostic value of tympanometry in otitis media with effusion.
Three particular applications of tympanometry are stressed. In the first place, tympanometric screening fails to give any appreciation of the tubal dysfunction evolution. During general anaesthesia, nitrogen oxide diffusion in the middle ear can hide effusion. Secondly, the correlation between tympanometric curves and middle ear effusion is far lower than usually assumed.
