Abstract：Objective To report treatment outcomes of titanium ossicular prostheses in one stage tympanoplasty. Methods Outcomes of one stage tympanoplasty using titanic ossicular replacement prostheses in 31 patients with 3 to 6 months follow-up were retrospectively reviewed. Pre- and postoperative pure tone thresholds as well as the air-bone gap were compared. Results Repaired tympanic membranes healed well at 1 month follow up in all 31 patients. No os-sicular replacement prosthesis protrusion was found, although infection occurred in 1 patient after 2 months. Mean air conduction hearing threshold was 59.27 ± 15.67 dB HL before tympanoplasty and 43.10 ± 14.64 dB HL after (P<0.05). The mean bone conduction hearing threshold was 23.06 ± 9.18 dB HL before operation, and 22.82 ± 7.49 dB HL after (P>0.05). The mean air bone gap (ABG) was 36.21 ± 11.88 dB before operation, and 19.40 ± 12.92 dB at followed up (p<0.05). The total effectiveness rate (post-operative ABG within 15 dB) was 41.94%(13/31). Conclusion Titanic os-sicular replacement prostheses in tympanoplasty with one stage ossicular chain reconstruction can produce satisfactory hearing results, with relatively few complications, and is worth popularizing.
