| description | Introduction
This prospective cohort study aims to analyze and compare the outcomes of ossiculoplasty in terms of hearing results, intra and post operative course, using autograft incus and titanium middle ear prosthesis.
Materials and Methods
Patients with a history of chronic ear discharge and conductive deafness were included in the study. Out of 21 patients with ossicular chain defect included in the study, 10 patients underwent ossiculoplasty with autograft incus and 11 with titanium prosthesis. Pure tone audiogram was done after three months.
Result
In patients with incus ossiculoplasty, average Post operative PTA was 43.5 dB ± 7.934SD and Net gain in hearing was 10.7 decibels ± 15.478SD. In patients with titanium prosthesis ossiculoplasty, average Post operative PTA was 41.4 dB ± 4.789SD and Net gain in hearing was 16 decibels ± 11.981SD.
Discussion
Three patients underwent only Tympanoplasty post operative PTA was 42 ± 5.292 dB (incus- 39 dB, titanium- 48dB) and hearing gain was 13.33 ± 12.583 (incus-20dB, titanium-0dB). Five patients underwent intact canal wall with Tympanoplasty: Post operative PTA was 35 ± 3 dB (incus-35dB, titanium-30dB) and hearing gain was 23 ± 15.379 (incus-18.33dB, titanium-30dB). Thirteen patients underwent canal wall down procedure with Tympanoplasty: Post operative PTA was 45.67 ± 5.228 dB (incus-50.4dB, titanium-41.8dB) and hearing gain was 9.33 ± 12.309 (incus-2.4dB, titanium-14.285dB). Complications in the short period studied were nil in both groups.
Conclusion
Incus and titanium have equal postoperative hearing but in terms of hearing gain Titanium prosthesis gave a better hearing gain than incus. |
