The new technique consists of interposing a fat graft between the 4 legs of the universal titanium prosthesis (Medtronic Xomed Inc, Jacksonville, FL, USA) to provide a more stable TORP in the ovale window niche. Normally, this prosthesis is designed to fit on the stapes\u2019 head as a partial ossicular replacement prosthesis. <\/jats:p><\/jats:sec><jats:sec><jats:title>Results:<\/jats:title><jats:p> The postoperative air-bone gap less than 25\u2009dB for the combined cohort was 69.2% and 41.7% for the TORP-F and the TORP-S groups, respectively. The mean follow-up was 17\u2009months postoperatively. By stratifying data, the pediatric cohort shows 56.5% in the TORP-F group (n\u2009=\u200952) compared with 40% in the TORP-S group (n\u2009=\u200929). However, the adult cohort shows 79.3% in the TORP-F group (n\u2009=\u200952) compared with 43.75% in the TORP-S group (n\u2009=\u200925). These improvements in hearing were statistically significant. There were no statistically significant differences in the speech discrimination scores. The only undesirable outcome that was statistically different between the 2 groups was the prosthesis displacement: 7% in the TORP-F group compared with 19% in the TORP-S group ( P\u2009=\u2009.03). <\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions:<\/jats:title><jats:p> The interposition of a fat graft between the legs of the titanium implants (TORP-F) provides superior hearing results compared with a standard procedure (TORP-S) in pediatric and adult populations because of its better stability in the oval window niche.
