Aim: To evaluate the early postoperative hearing results after Incudo-stapedial rebridging versus partial ossicular replacement prosthesis application in cases of incudo-stapedial discontinuity due to chronic suppurative otitis media.

Study Design: A prospective randomized comparative clinical trial.

Place and Duration of Study: Otolaryngology Department, Tanta University, Egypt from January 2018 to June 2021.

Methodology: Inclusion criterion was cases with CSOM with ABG more than 30 dB and adequate cochlear reserve. Study population were sixty consecutive cases with incudo-stapedial erosion more than 2-millimeter gap. Thirty of them were candidates for incudo-stapedial rebridging using tragal cartilage strip graft and glass ionomer bone cement. The other thirty patients were candidates for PORP. Tympanoplasty was done for each case of the two groups.

Main Outcome Measures: hearing assessment following surgical procedures.

Results: Postoperative air conduction significantly decreased compared to baseline in each group. By comparing the results of both techniques, pre and postoperative air conduction were insignificantly different.

ABG significantly decreased postoperatively compared to baseline in each group. By comparing between both techniques, pre and postoperative ABG were insignificantly different.

Conclusions: Among chronic suppurative otitis media patients with ossicular erosion, our study showed that PORP and cartilage graft with glass ionomer bone cement effectively improved hearing levels when used for the reconstruction of the incudostapedial joint during tympanoplasty.
