To analyze and compare the outcomes of ossiculoplasty in terms of hearing results and intra and post operative course, using autograft incus and titanium middle ear prosthesis in patients with ossicular chain erosion. Patients between 12 and 60 years of age with a history of chronic ear discharge with moderate conductive deafness (>40 dB HL) were included in the study. The patients
after assessment of ossicular erosion were subjected to ossiculoplasty with autologous incus or titanium prosthesis randomly. The patients were followed up after 3 months to analyze the functional and anatomical results. Out of 21 patients with ossicular chain defect were included in the study, of whom 10 patients underwent ossiculoplasty with autograft incus and 11 with titanium prosthesis.
Postoperative hearing evaluation by pure tone audiogram was done after 3months, which showed successful hearing Complications and extrusion rate were nil. In patients with incus average Post operative pure tone average was 43.5 dB and Net gain in hearing was 10.6 decibels. In patients with titanium prosthesis, average Post operative pure tone average was 41.4 dB and Net gain in hearing was 15.9 decibels. Incus and titanium has equal postoperative hearing. In terms of hearing gain Titanium prosthesis gave a better haring gain than Ossicular transposition.
Complications in the short period studied are nil in both groups
