Impedance audiometry in serous otitis media.
The relationship between the results of impedance audiometry and middle ear effusion in serous otitis media was examined in 76 ears immediately prior to myringotomy. Tympanometry and acoustic reflex threshold showed the highest correlation with the operative findings relative to middle ear effusion. The combination of tympanometry and acoustic refex threshold was superior to the use of either component alone. Results are discussed in terms of clinical implications with specific consideration of hearing screening programs.
