DIAGNOSIS OF LATENT DYSFUNCTION OF AUDITORY TUBE

Seleznev S.B., Shydlovskaya T.V. (Kiyev)

Summary

The authors studied a possibility of diagnosis of latent dysfunction of auditory tube by qualitative and quantitative assessment of tympanometry and "compression-decompression" test data. Comparative evaluation of tympanometry data was carried out in healthy persons with normal hearing and in the patients with normal hearing and otoscopic picture but with pathology of nasal cavity and nasopharynx, and in the patients with clinical signs of tubal dysfunction. Obtained data show significant difference in the indices of pliability, tympanogram gradient, intratympanal pressure in "compression-decompression" test in these groups that can be useful in differentiation between normal and pathologic states of middle ear sound conduction structures.
