				        	Objective Tostudytheeffectsoftitanicartificialossiclereplacementincanalwall - downandcanalwall-up tympanoplasty for patients suffering from chronic otitis media .Methods A total of 157 cases (164 ears) un-derwent canal wall-down and canal wall -up tympanoplasty at our hospital from Feburary 2014 to Feburary 2016 were retrospectively analyzed ,in which 50 cases in canal wall down tympanoplasty with titanic ossicle replacement , 49 cases without replacement ,42 cases in canal wall -up tympanoplasty with titanic artificial ossicle replacement , and 23 cases without replacement .The average air bone gaps (ABG) before and 3 months after operations were re-corded and the average reduced ABGs were compared between sub -groups to evaluate the effects of titanic artificial ossicle replacement .Results In the canal wall-down tympanoplasty group ,the mean ABGs of 3 months after oper-ations in the replacement subgroup was 15 .72 ± 11 .18 dB ,the reduced ABGs was 17 .45 ± 5 .23 dB ,and the impro-ving rate for hearing was 71 .54% ,statistically higher than the non -replacement subgroup(P<0 .05) .In the canal wall-up tympanoplasty group ,the mean ABGs of 3 months after operations in the replacement subgroup was 8 .13 ± 5 .37 dB ,the reduced ABGs was 26 .85 ± 11 .03 dB ,the improving rate for hearing was 75 .12% ,statistically higher than non-replacement subgroup(P<0 .05) .Conclusion The replacement of titanic artificial ossicle in both of canal wall-down and canal wall-up tympanoplasty is helpful to improve hearing .
