N2 - Objective: To compare the complication rate and hearing results of a new, lightweight, titanium ossicular replacement prosthesis with Plastipore prostheses (Xomed, Jacksonville, FL). Study Design: Retrospective. Methods: Charts were reviewed for type of operation, type of prosthesis used, extrusion rate, prostheses failure rate, and hearing thresholds at multiple frequencies and at multiple follow-up points. The dependant variable for hearing results was the four-frequency average air-bone gap. Results: There were 84 patients undergoing tympanoplasty with the Plastipore prosthesis and 53 with the titanium. There was one extrusion in the titanium group. There was an additional single incidence of prosthesis failure in the titanium group. Overall hearing results were comparable with an air-bone gap average of 19.3 dB in the Plastipore group compared with the titanium group with an air-bone gap of 22.0 dB (P = .08). Sixty percent of patients had a postoperative air-bone gap of 20 dB or less in the Plastipore group. In the titanium group, 45.3% achieved a 20 dB or less postoperative air-bone gap. Plastipore had a lower air-bone gap than the titanium when a canal wall up operation was performed (17.8 vs. 23.9 dB) and tended toward a lower air-bone gap when a total ossicular prosthesis was needed (22 vs. 27 dB) (P

Prosthetic-Joint Infections — NEJM

The primary goal of surgery for chronic otitis media is the achievement of a safe, dry ear, disruption of recurrent ear drainage, and hearing improvement. Primary surgery consists in eradication of the disease (cholesteatoma and/or irreversibly diseased mucosa), which creates a middle ear fistula with air occupation, restoring the integrity of the tympanic membrane. In our service, ossicular chain reconstruction with titanium prostheses is performed in a single surgical stage in all cases, except in those in which complete resection of the problem is questionable, and when there is severe mucosal stripping.

We performed a retrospective study of all data obtained from patients undergoing ossicular chain reconstruction with titanium prosthesis at our department from 1999 to 2008, which included 124 ossiculoplasties performed by different surgeons in our Department.

Duesseldorf Type Titanium Prosthesis BELL / ARIEL ..

N2 - Objective: Limitations in biocompatibility and hearing improvement with ossicular chain reconstruction prostheses are addressed with new, lightweight titanium prostheses designed to maximize visualization of the capitulum and footplate regions. The effectiveness of these new prostheses is being tested in a prospective multicenter study. Study Design: Prospective case series. Setting: Multicenter (8 sites), primarily tertiary private practice or academic otologic clinics. Patients: A convenience sample of 31 patients undergoing ossiculoplasty, with 16 partial ossicular chain reconstructions using the Bell prosthesis and 15 total reconstructions using the Aerial prosthesis. Intervention: Ossiculoplasty using new Kurz titanium prostheses. Cartilage was interposed between the tympanic membrane and the prosthesis. Main Outcome Measures: Air-bone gap for pure tone average and 3,000 and 4,000 Hz, assessed preoperatively and 3 months, 6 months, and 12 months postoperatively; percent of patients obtaining an air-bone gap of ≤20 dB; high-frequency average (1,000, 2,000, and 4,000 Hz) to evaluate sensorineural hearing loss; and extrusion rate. Results: A postoperative air-bone gap of ≤20 dB was obtained in 81% of Bell prosthesis patients and 67% of Aerial prosthesis patients at 3 months. The results were stable to improved for later time intervals. High-frequency gaps were similar to the pure tone average gap. To date, there have been no instances of extrusion, and all the surgeons found the prostheses easy to use and thought that the design characteristics facilitated accurate placement. Conclusions: Initial evaluation of the Kurz titanium prostheses produced low extrusion rates (none to date) with excellent hearing results, including good high-frequency conduction. Good visualization and accurate placement were easy to achieve. Further studies are needed to confirm long-term efficacy.
