Background: Ossiculoplasty improves conductive hearing loss. Various reconstruction methods and techniques are developed with use of different graft materials over period of time. Results of ossiculoplasty can be predetermined with consideration of prognostic factors.
Methods: The present study is retrospective study of 50 patients who underwent ossiculoplasty in the medical college hospital over the period of 3 years i.e. from January 2013 to December 2016. The pre-operative and post-operative audiometric findings were documented and analyzed to study the hearing improvement with the use of auto graft malleus and incus for ossiculoplasty. The results of ossiculoplasty were also compared with other studies done for ossiculoplasty. Predictors of ossiculoplasty results such as ossicular status and middle ear mucosa were also studied.
Results: The average post-operative air bone gap was 12.92 dB. The mean post-operative ABG was within 20 dB in both primary and revision cases. Average air-bone closure in patients with normal mucosa was 32.1 dB and that of adhesive mucosa was 18 dB. Significant improvement in post-operative air-bone closure (p <0.01) was observed in patients with auto graft incus than malleus head as ossiculoplast.
Conclusions: 84% ossiculopasty patients were having post-operative air bone gap within 20 dB. The ossiculoplasty using auto graft ossicle is physiological, biocompatible, stable and has low complication rate.
