“…To be successful in restoring hearing, an ideal prosthesis has to be 1) biocompatible; 2) easy to position; 3) stable in its position, 4) but mobile enough to mechanically transmit sound waves through the footplate; and 5) long‐lasting. A variety of studies have demonstrated reasonable success with titanium‐based prostheses by these criteria . Coffey et al demonstrated that titanium prostheses produce significantly superior early hearing outcomes, such as postoperative ABG, ABG closure, SRT, and SRT improvement, as compared to nontitanium prostheses such as hydroxyapatite .…”

“…Titanium as an implant material has shown excellent biocompatibility in both orthopedic and craniofacial surgery and has been used in ossicular reconstruction since 1996 . As an ossicular prosthesis, titanium has an optimal mass and stiffness to aid in acoustic transmission, providing low acoustic impedance with minimal dampening of sound . The low complication rates associated with titanium ossiculoplasty (namely prosthesis extrusion and displacement) have been attributed to its biostability.…”

“…Such results are predictable in view of the prosthesis design whereby the use of titanium as an implant material affords the prosthesis with an optimal combination of mass and stiffness to aid in acoustic transmission [12]. Additionally, the incorporation of a filigree design in the implant head allows for improved visualisation and therefore more accurate localisation for implant placement.…”

“…Nowadays, titanium prostheses are preferred because they are more stable to air pressure changes and resorption compared with autologous material . They feature high biocompatibility and convenient handling by length adjustability and, from animal experiments, have been found to be safe with good epithelialization …”

Objectives To compare the results of ossiculoplasty with two different partial ossicular replacement prostheses (PORP) to ossiculoplasty with a total ossicular replacement prosthesis (TORP) in patients with an intact stapes suprastructure. Methods All patients required primary or revision surgery for chronic middle ear disease and ossicular reconstruction with either a PORP or a TORP, as well as a with an intact stapes suprastructure. In total, 141 patients 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 were included in this study. The inclusion criterion was an intact stapes suprastructure. The underlying indication for surgery was either middle ear disease, such as cholesteatoma, or revision surgery for audiological improvement. The main outcome measures were four‐frequency pure tone average (0.5, 1, 2, 3 kHz) at early and late follow‐up after ossiculoplasty, the effects of clinical factors including the underlying middle ear disease, and primary or revision surgery. Results All patients showed 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). A significantly better outcome in ABG closure was shown among patients with a preoperatively intact tympanic membrane, with an intact stapes suprastructure or without preexisting cholesteatoma. Outcome was not significantly influenced by the prosthesis‐type, the creation of an open mastoid cavity, the status of the mucosa, or the indication for surgery. Conclusion TORP with an intact stapes suprastructure is a safe procedure and provides audiological outcomes similar to PORP. Level of Evidence 2C Laryngoscope, 130:768–775, 2020
