Figure 2B shows that disappointing postoperative audiometric results were seen in 11 of the 30 ears (cases 9, 13, 15, 16, 20, 21, 23, 24, 26, 29, and 30). Reexploration was performed in 8 ears (cases 4, 9, 20, 23, 24, 26, 29, and 30). Successful reconstruction was performed in 3 ears (cases 4, 23, and 24). In 2 of these ears (cases 4 and 23), revision surgery was necessary because of Teflon piston luxation; in 1 ear (case 24), recurrent bony closure of the footplate after stapedotomy necessitated revision surgery. In ear 23, the perceptive hearing impairment was encountered during the period between 1 year after surgery and the time of reexploration. None of the reconstructions performed in the other 5 cases were successful. In 1 of 5 ears (case 9), epitympanic ossicular refixation necessitated remodeling of the incus to create a malleostapedotomy. In the second ear (case 20), the disappointing result supported reexploration, and mobilization of the fossa incudis fixation was performed. In case 26, the stapedotomy opening seemed too small, necessitating partial platinectomy, but conductive hearing loss remained after revision. In case 29, a luxation of the Teflon piston perforated the tympanic membrane; during revision surgery, a new piston was added, but the reason for the remaining ABG remains elusive. In 1 patient (case 30), acquired cholesteatoma was observed a few years after primary surgery. Perceptive hearing impairment was obtained in 5 ears (cases 9, 20, 23, 24, and 29), and usually the impairment occurred slowly after reexploration and was progressive. Although not all revisions were successful (cases 9, 20, 26, 29, and 30), the hearing results of this series can generally be considered worthwhile.
