Abstract:
Objective To investigate the therapeutic effects of titanium artificial auditory ossicles in closed type mastoid radical tympanoplasty ,in comparison with ceramic artificial auditory ossicles .Methods A retrospec‐tive analysis was done on of 150 patients (155 ears) with the closed type of mastoid radical tympanoplasty using arti‐ficial auditory ossicles for hearing reconstruction (from January 2008 to December 2012) ,cund were ,and followed up for 12 months .Based on the two kinds of artificial auditory ossicle materials ,the group was divided into two :122 cases (127 ears) for the titanium auditory ossicle group and 28 cases (28 ears) for the ceramic auditory ossicle group .We compared the average air conduction hearing threshold and air bone gaps (ABG) at 0 .5 ,1 .0 ,2 .0 ,and 4 .0 kHz ,at preoperative 6 months and postoperative 6 ,12 months .Results For the Titanium artificial auditory os‐sicle group:117 ears (92 .13% ) had hearing threshold improvement >15 dB HL ,106 ears of the ABG change ≤20 dB ,which were statistically significant .The total success rate of hearing reconstruction was 83 .46% (106/127) . For the ceramic auditory ossicle group:5 ears (17 .86% ) had hearing threshold improvement >15 dB HL ,3 ears (10 .71% ) of the ABG change ≤20 dB ,which was no statistical significance between the two groups .Conclusion The hearing reconstruction effects of titanium artificial auditory ossicle in closed type mastoid radical tympanoplasty is excellent .It is suitable for application in closed-mastoidectomy tympanoplasty ideal artificial auditory ossicle .
