Immediate posterior canal wall reconstruction by alloplastic bone cement

ABSTRACT

To evaluate the author's experience in immediate reconstruction of the posterior canal wall [PCW] using Polymethyl Methacrylate [PMMA] bone cement. Between January 2004 and March 2006, PMMA bone cement was used for immediate reconstruction of the posterior canal wall in 28 patients undergoing mastoidectomy procedure for removal of cholesteatoma. The age of the patients ranged from 18 to 48 years. The patients were followed up with a mean of 16 months. In 28 patients the PCW defect was reconstructed successfully by PMMA bone cement with normal appearance of the external canal skin in 27 patients. Postoperative complications included middle ear infection in 3 cases, granulation tissue in 4 cases and dehiscence of the external canal skin in one case. From this study, the use of PMMA bone cement is a reliable and easy alternative method for repair of bony defects in the posterior canal wall
