“…In former days, the diagnosis of OI has put off otologists to perform stapes surgery because of a higher risk of complications, such as bleeding of the mucosa, ossicular atrophy and the progressive character of the sensorineural hearing loss component inherent to the disease [Cremers and Garretsen, 1989], though, during the last few decades, reports on the results of stapes surgery in larger series of OI patients [Shea and Postma, 1982;Pedersen 1985;Cremers and Garretsen, 1989;Garretsen and Cremers, 1990;van der Rijt and Cremers, 2003;Kuurila et al, 2004;Vincent et al, 2005;Swinnen et al, 2009] have shown that a successful reduction in hearing thresholds may be expected in the majority of the OI patients with conductive hearing loss. Nevertheless, a few cases of total deafness following surgery have been reported [Garretsen and Cremers, 1990;van der Rijt and Cremers, 2003;Kuurila et al, 2004], as well as less beneficial results when revision surgery is concerned [Shea and Postma, 1982;Garretsen and Cremers, 1991b;van der Rijt and Cremers, 2003].…”
