Background: CSOM and associated hearing loss is significant in our society and an effort directed towards the assistance of those who are afflicted is indeed worthwhile. The problem of ossicular reconstructions for CSOM in difficult chronic ears however continues to represent a major rehabilitation challenge. Various materials have been used in reconstruction of middle ear including synthetic, bony and cartilaginous materials.
Methods: The present study was prospective observational study of 50 cases who underwent ossiculoplasty for middle ear surgery over the period of 2 and half years. CSOM patients with hearing loss >40 dB were included and patients with sensorineural hearing loss were excluded out from the study. Otoscopic examination, tuning fork tests, and examination under microscope were done in all the patients.
Results: A total number of 50 patients were included in the study. Graft was taken up in 90% cases and rejected in 5% subjects after 3 months postoperatively. The average pre-operative air-bone gap was 45±3.60 dB while the average post-operative air-bone gap was 25.66±9.25 dB. The average hearing gain was 19.34 dB which was statistically significant (p=0.000).
Conclusions: This study concluded that ossiculoplasty with an autologous incus graft is safe surgical approach with good results for reconstructing the ossicular chain due to lower extrusion rate with good post-operative hearing gain.
