Outcomes with gold wire and XXXX partial ossicular replacement prostheses in type 2 tympanoplasty: a preliminary study.

@entity692 @entity1 @entity102
UNASSIGNED: Objectives: To compare the hearing results and graft take rates of the recently developed gold wire prosthesis with those of the @entity692 partial ossicular replacement prosthesis in @entity1 with @entity102 media. Method: This retrospective study examined @entity1 who underwent type 2 tympanoplasty with a minimum follow up of one year. The study population consisted of 32 @entity1 in the partial ossicular replacement prosthesis group and 26 @entity1 in the gold wire group. The main outcome measures were the graft success rate and level of hearing improvement. Complications and extrusion rates were also noted. Results: The graft take rate was 90.6 per cent for the partial ossicular replacement prosthesis group and 92.3 per cent for the gold wire group (p  =  0.848). Pre-operatively, there were no significant differences in the air or bone-conduction thresholds between groups. Post-operatively, the mean hearing gain was 18.5      14.0  dB in the partial ossicular replacement prosthesis group and 16.5      10.6  dB in the gold wire group (p  =  0.555). The mean air-conduction thresholds were 26.6      12.4 and 32.6      10.5  dB, respectively (p  =  0.027), and the mean bone-conduction thresholds were 9.7      7.0 and 10.4      6.4  dB, respectively (p  =  0.687). Conclusion: The success and complication rates provided by the gold wire prosthesis seem comparable to those of the @entity692 partial ossicular replacement prosthesis.
