Abstract:
Objective To summarize and analyze the pathogenesis ,methods of hearing reconstruction and curative effect of mixed hearing loss .Methods Patients with mixed hearing loss who underwent hearing reconstruc-tion from Jan 2009 to Dec 2011 in the ENT department of PLA General hospital were reviewed retrospectively .Af-ter the operation ,air conduction (AC) ,bone conduction (BC) ,air-bone gap (ABG) at main frequencies and audi-ometry changes were analyzed .Results Among 32 cases ,15 cases were chronic otitis media ,13 cases otosclerosis , 2 cases Van der Hoeve ,and 2 cases congenital middle ear malformations .There were 26 cases with significantly im-proved hearing after surgery ,and the effective rate was 81 .25% .AC showed great improvement at 0 .25~4 kHz (P<0 .05) while there was no change at 8 kHz (P>0 .05) .BC showed improvements at 1 and 2 kHz and improved significantly only at 2 kHz .After operation ,pure tone audiometry at AC and BC separately improved 24 .94 ± 8 .15 dB and 5 .90 ± 7 .96 dB;ABG narrowed down to 19 .04 ± 11 .06 dB .Conclusion Mixed hearing losses are mostly seen in chronic otitis media and tympanosclerosis .After auditory rehabilitation ,patients can experience improved hearing .
