Between January 2014 and December 2019, we performed 10 revision stapes surgeries at our hospital for hearing loss. We retrospectively reviewed the data of the 10 cases to determine the causes of failure and evaluate the hearing outcomes. The identified reasons for primary surgery failure were eroded incus (4 cases), dislocated prosthesis (2 cases), prosthesis fixation (3 cases), short prosthesis (1 case), malleus ankylosis (1 case), stapes refixation (1 case), and incomplete previous operation (1 case). In 7 of the 10 cases (70%), successful hearing outcomes, as assessed based on the criteria proposed by the Japan Otological Society (2010), were obtained. The postoperative air-bone gap was 10 dB or less in 3 cases (30%), and 20 dB or less in 8 cases (80%). One patient developed sensorineural hearing loss (≥ 15 dB).
Revision stapes surgery is less likely to be successful than the primary operation, and sensorineural hearing loss as a postoperative complication occurs more frequently after revision surgery than after primary surgery. However, in cases where a definite reason for failure of the primary surgery is identified, hearing improvement is likely to be obtained after revision surgery. We should offer revision stapes surgery proactively to patients, with careful selection of suitable candidates.
