A Comparative Study of Ossicular Reconstruction with TORP/PORP Versus Autologous Bone in Middle Ear Surgeries

Chronic otitis media causes considerable morbidity in the form of hearing disability to the patient. Otologists aim to achieve through their surgery a near normal neo-membrane with continuous ossicular chain and a postoperative middle ear status which functionally bears close resemblance to the normal state. The objective of this study is to compare ossicular reconstruction with TORP/PORP versus autologous bone and compare the air–bone gap before and after surgery. This study was done at a tertiary care referral center. Eighty patients of chronic otitis media were divided into two groups and patients underwent cortical mastoidectomy with ossicular reconstruction in the form of TORP/PORP in one group and autologous bone in another. In the TORP/PORP group, the mean preoperative air–bone gap was 45.4 dB which was reduced to a mean air–bone gap of 19.45 dB. In the bone ossiculoplasty group, the mean preoperative air–bone gap was 43.38 dB which was reduced to a mean air–bone gap of 21.84 dB postoperatively. This study indicated that patients who underwent reconstruction with TORP/PORP had better improvement than those who received autologous bone. The results were statistically significant. Two cases who received TORP/PORP had extrusion due to infection. The patients were followed up till 1 year postsurgery.
