Background & Objectives: Various materials have been used for ossicular reconstruction, but there have been no reports for titanium prosthesis in South Korea. The purpose of this study was to assess the hearing results of Kurz titanium prosthesis in chronic ear diseases.
Subjects & Methods: A retrospective review was made of 62 cases who underwent ossicular reconstruction using either titanium (TTP(R)-VARIO System) or plastipore (Polycel(R)) prosthesis from January 2003 to July 2005. Postoperative hearing results were analyzed taking in several prognostic factors such as the condition of middle ear mucosa and ossicle, or surgical method.
Results: A postoperative air-bone gap of E20 dB was obtained in 75.6% of the titanium and 56% of plastipore ossiculoplasty. The Postoperative ABG (air bone gap) show better results in healthy middle ear mucosa and in those cases which contain stapes superstructure.
Conclusion: Titanium have a good biocompatibility and low extrusion rates with excellent hearing results. Besides, good visualization and accurate placement were easy to achieve.
