Abstract
Background: Chronic otitis media (COM) is defined as a perforation of the tympanic membrane with persistent drainage of pus from the middle ear lasting at least two weeks. Tympanoplasty is a surgical procedure in ENT practice which aims at removal of diseased pathology from middle ear along with reconstruction of sound conducting mechanism by reconstructing the ossicular chain with various materials. Methods:All the cases of CSOM with ossicular chain deformity were included. Ear examination was done in detail, Preoperative hearing assessment was done and Hearing loss was calculated by average air bone gap on PTA.For Auto graftstragal cartilage or incus was used andfor allograft Teflon TORP/PORP with cartilage cap was used. Results: Comparison forossiculoplasty was done by comparing its advantages and disadvantages in the terms of extrusion rate and hearing restoration in postoperative period. Overall failure rate for autologous material was 8% and for alloplastic material was 12%. Conclusion: the use of autologous graft is more advantageous in terms of surgical outcome, extrusion rate, and postoperative hearing gain.
