The average period of use was 16.6 \u00b1 3.3 years (21 years at most). The incidence of problems was lower with the second version of the device compared to the first version. Frequencies of the troubles were related to the types of original ear diseases: seven of 17 cases with chronic otitis media (41.2%), two of seven cases with cholesteatoma (28.6%), and two of six cases with tympanosclerosis (33.3%). No cholesteatoma occurred after surgical procedures (i.e., external ear canal closure and tympanic membrane lateralized) (<jats:italic>P<\/jats:italic> = 0.06). The device was exposed through a retroauricular skin fistula where the internal coil had been implanted. Significantly fewer infections were observed when the two\u2010stage operation was used (<jats:italic>P<\/jats:italic> = 0.01).<\/jats:p><\/jats:sec><jats:sec><jats:title>CONCLUSION<\/jats:title><jats:p>For long\u2010term success in implantation of the IHA, careful control of middle ear inflammation and measures against eustachian tube dysfunction are required in addition to technological advancements.<\/jats:p><jats:p>\u00a9 2010 American Academy of Otolaryngology\u2010Head and Neck Surgery Foundation.
