Otomicroscopy often revealed a break in the smooth contour of the manubrium. All patients had air\u2013bone gaps on audiometry, especially at higher frequencies. Tympanometry showed hypermobility of the tympanic membrane in four patients who were tested. Laser-Doppler vibrometry revealed increased umbo velocity in four out of five patients. Four patients were treated conservatively. One patient underwent exploratory tympanotomy with successful ossiculoplasty.<\/jats:p><\/jats:sec><jats:sec id=\"S0022215107000990_sec5\"><jats:title>Conclusions:<\/jats:title><jats:p>Isolated fracture of the manubrium is a rare condition which may present as sudden-onset hearing loss after digital manipulation of the external auditory canal. The diagnosis can be made on the basis of otomicroscopy, audiometry, tympanometry and laser-Doppler vibrometry.
