Tympano-ossiculoplasty utilizing the Spiggle and Theis titanium total ossicular replacement prosthesis.
Laryngoscope 2003 September
OBJECTIVE: Since 1993, titanium prostheses have been used in Europe as a biocompatible implant for ossicular reconstruction. More recently, the titanium ossicular prosthesis has become more widely available in the United States as a newer means of surgical restoration of hearing. We will review the hearing results of patients who have undergone tympano-ossiculoplasty using a titanium total ossicular replacement prosthesis (TOP). We will compare these results to our previously published results using the porous polyethylene TOP.
METHODS: Retrospective review in a tertiary otologic practice.
RESULTS: Eighteen patients underwent tympano-ossiculoplasty with a titanium TOP. Among these patients, 10 cases involved revision of a previously placed ossicular prosthesis. Hearing results showed that 16 of 18 patients (89%) had closure of the postoperative air-bone gap to within 20 dB, and the average air-bone gap improvement was 23 dB. The average follow-up time was 8 months (range, 2-21 months). The results of this initial evaluation compare favorably with the results that we obtained using a porous polyethylene TOP in which 67% of 133 patients closed the air-bone gap to within 20 dB.
CONCLUSION: We have recently begun using the titanium TOP, which has resulted in improved postoperative hearing when compared with the porous polyethylene TOP. In the future, longer follow-up and increased patient numbers will strengthen our conclusions.
