Comparison of total and partial ossicular replacement prostheses in patients with an intact stapes suprastructure
The Laryngoscope May 17, 2019
Weiss NM, et al. - Ossiculoplasty with two different partial ossicular replacement prostheses (PORP) was compared to ossiculoplasty with a total ossicular replacement prosthesis (TORP) in patients with an intact stapes suprastructure. Researchers analyzed 141 patients who receiving classic tympanoplasty with PORP (N = 92), ossiculoplasty with PORP with ball joint (N = 22), or TORP (N = 27) between January 2011 and March 2017. A significantly reduced air-bone gap (ABG 0.5, 1, 2, 3 kHz) at late follow-up (mean: 18 dB) compared to preoperative measurements (mean: 25.5 dB) was reported in all patients. Findings support that it is safe to perform TORP with an intact stapes suprastructure. This procedure renders audiological outcomes similar to PORP.
