Twenty-one ears were treated by canal wall down mastoidectomy and 40 ears by canal wall up mastoidectomy. The follow-up period was 3 to 6 years (average 4.2 years). Pure tone averages for thresholds at 0.5, 1, 2 and 3 kHz were calculated using standard conventional audiometry.<\/jats:p><\/jats:sec><jats:sec id=\"S0022215114002023_sec3\"><jats:title>Results:<\/jats:title><jats:p>The pre-operative mean air\u2013bone gap of 31.6 dB, for all ears, was reduced to 20.3 dB post-operatively. For the 40 canal wall up ears, this value decreased from 30.8 dB to 19.9 dB, and for the 21 canal wall down ears it decreased from 33.0 dB to 21.0 dB. The differences between the pre- and post-operative mean air\u2013bone gap values were significant.<\/jats:p><\/jats:sec><jats:sec id=\"S0022215114002023_sec4\"><jats:title>Conclusion:<\/jats:title><jats:p>No cases of extrusion, necrosis or resorption were exhibited for the autogenous mastoid cortical bone prosthesis.
