“…For ossiculoplasty with a PORP, recently published studies have reported various mean improvements in ABG, including 8.9 dB (standard deviation [SD] 10.3 dB; n = 47), 10 13 dB (SD 13 dB; n = 44), 11 and 14.2 dB (SD 15.3 dB; n = 52). 12 In the present study population, the ABG improved by 8.5 dB (n = 141), which is slightly lower compared to other studies.…”

“…10 The patients in this study achieved an ABG of less than 20 dB, which is a common goal for successful hearing improvement. [10][11][12] There are several factors under discussion that influence the audiological outcome of middle ear surgery. The underlying middle ear disease, 7,13 status of the malleus handle, 7,14-17 ventilation and mucosa of the middle ear, 7,17 presence of the stapes suprastructure, 7,13,14,17 surgical technique (e.g., canal wall up [CWU] vs. canal wall down [CWD]), 14,15,18 reconstruction material, 14,19,20 surgeon's experience, 15 and number of previous ear surgeries 16 seem to play a role in the outcome of surgery.…”

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

“…One or all of these factors can have implications in the use of ossicular prostheses, extrusions and middle ear sound conduction. Similar hearing outcomes have been observed in other studies on type 3 ossicular reconstruction using titanium prostheses [16,20,21].…”

To evaluate the functional and hearing outcomes using full thickness broad cartilage palisades for tympanic membrane reconstruction in type 3 tympanoplasty with titanium prostheses. The retrospective study performed at a tertiary referral institute included 30 patients with posterior mesotympanic retraction pockets or tympanic membrane perforations requiring tympanic membrane and type 3 ossicular reconstruction. Patients with disease extending beyond the aditus requiring canal wall down mastoidectomy were excluded. Disease removal from posterior mesotympanic and epitympanic recesses was confirmed using angled endoscopy and ossicular reconstruction was performed using titanium partial or total ossicular replacement prostheses. Tympanic membrane reconstruction was done, with or without attic reconstruction, using full thickness broad cartilage palisades harvested from the tragus with perichondrium attached laterally. Patients were assessed at 24 and 48 weeks for graft status and any evidence of implant extrusion. Hearing evaluation was done using subjective assessment and pure tone audiometry. In total, 27 out of 30 patients had intact and completely healed grafts at 48 weeks postoperatively (a success rate of 90 %) showing full union and epithelialization of palisades, and with three patients displaying small defects. The mean pure tone air bone gap pre-and postoperatively was 32.4 and 8.8 dB, respectively, with most patients reporting satisfactory postoperative hearing. No evidence of implant extrusion was found in the 48-week period. Tympanic membrane reconstruction using full thickness palisades of tragal cartilage provides good functional and hearing outcomes in type 3 tympanoplasty with titanium prostheses.

“…Different materials are used for ossiculoplasty, including homologous materials (ossicules, cartilage) and synthetic materials (plastipore, ceravital, hydroxyapatite, metal, titanium) 1 2 . Titanium has many advantages in terms of biocompatibility, weight and acoustic performance 3-5 . It is also compatible with MRI at 1.5 and 3 tesla 6 7 , which is of primary importance, especially in cholesteatoma surgery.…”
