Objective 

Investigating the outcomes of a surgical approach to treat isolated defects of the stapes suprastructure, using a modified total ossicular replacement prosthesis (TORP) prosthesis as a PORP between the footplate and the incus, effectively creating a TORP-PORP configuration.

Patients 

Eleven patients (mean age, 37.2 years; 36% male and 64% female) between the years 2007 and 2022.

Intervention(s) 

Therapeutic (ossiculoplasty).

Main Outcome Measure(s) 

Hearing gain (in dB) in air conduction thresholds at 0.5, 1, 2, 3, and 4 kHz, stability of bone conduction, revision rate.

Results 

Significant improvement in air conduction between the preoperative and the postoperative cohorts (p = 0.002) with a mean postoperative hearing level of 30.00 ± 5.25 dB. The bone conduction remained stable. We encountered no perioperative complications, and there were no revisions surgery.

Conclusions 

The described ossiculoplasty procedure is a safe and effective approach to treat isolated defects of the stapes suprastructure.
