The stapes velocity for excitation by exponential sweeps from 400 to 10,000\u00a0Hz was measured with a laser Doppler vibrometer. The resulting middle ear transfer functions were compared with the reconstructed middle ear. For clinical evaluation, 23 ears in 21 patients with chronic otitis media and an intact ossicular chain were operated using CBST. At each follow-up visit, the patients underwent pure-tone audiometry and the Freiburg monosyllabic speech test at a presentation level of 65\u00a0dB SPL for the word recognition score (WRS).<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Results<\/jats:title>\n                <jats:p>The measured stapes velocities at one-third octave midband frequencies averaged 3.56\u2009\u00d7\u200910<jats:sup>\u20132<\/jats:sup>\u2009\u00b1\u20099.46\u2009\u00d7\u200910<jats:sup>\u20133<\/jats:sup> (mm\/s\/Pa) compared to 3.06\u2009\u00d7\u200910<jats:sup>\u20132<\/jats:sup>\u2009\u00b1\u20096.86\u2009\u00d7\u200910<jats:sup>\u20133<\/jats:sup> (mm\/s\/Pa) with the bending and underlay cartilage in place (<jats:italic>p<\/jats:italic>\u2009=\u20090.319; <jats:italic>r<\/jats:italic>\u2009=\u20090.32).
