OBJECTIVE: To study the bone conductive @entity393 in @entity2346 media with effusion (OME). METHOD: Fifty adults of OME treated in our hospital, from Mar. 2009 to Feb. 2010, were enrolled for analyzing bone conduction @entity393 (BCHL) before auripuncture and after auripuncture, the difference between which were compared in 51 ears. BCT of pre auripuncture 24 subjects, BCT of post-auripuncture 22 subjects, and BCT recovered from OME 9 subjects compared with the contralateral ear respectively. High and extend high frequency (8, 10, 12, 16 kHz) air conduction threshold (ACT) after recover from OME was compared to the normal contralateral ear in 4 adults. RESULT: BCT improved significantly after auripuncture at the frequencies (0.5-4.0 kHz), and the improvements in 4.0 kHz are more than that in 0.5 kHz significantly (P<0.05). In the unilateral OME subjects, BCT, of post auripuncture and recovered from OME, nearly recovered to the same level as the contralateral ear in most cases. While high and extend-high frequency (8, 10, 12, 16 kHz) ACT elevated in 3 of 4 @entity1 recovered from OME. CONCLUSION: Both effusion in middle ear and @entity389 result in the elevation of BCT. Elevation of BCT at regular frequencies (0.5-4.0 kHz) is frequently associated with the effusion in middle ear, while these frequencies were insensitive in the early @entity389 . The high and extend high frequency ACT elevation may be sensitive for the early @entity1274 . As the disease prolonged, @entity1274 of the lower frequencies (0.5-4.0 kHz) could be detected of OME @entity1 .
