Are there differences in revision stapes surgery outcomes between university and county clinics? A study from the quality register for otosclerosis surgery in Sweden

• Purpose The aim of the study was to investigate hearing outcomes in stapes revision surgery with regard to the type of clinic (university clinic or county clinic). Furthermore, the aim was to investigate the risk of complications with a focus on tinnitus, hearing deterioration, and taste disturbance 1 year after surgery. Methods The study is based on data from the Swedish Quality Register for Otosclerosis Surgery (SQOS). Two study protocols were completed by the surgeon, and a questionnaire was distributed to the patients 1 year after surgery. A total of 156 revisions were available for analysis with both preoperative and postoperative audiometry data. Results Seventy-five percent of the patients reported better to much better hearing 1 year after revision surgery. An air bone gap <= 20 dB postoperatively was seen in 77% of the patients. Four percent had hearing deterioration >= 20 dB PTA(4) AC. Eleven percent had worsened or newly developed tinnitus, 5% had taste disturbance, and 3% had dizziness 1 year after surgery. Preoperative and postoperative hearing did not differ between patients operated on in university vs. county clinics. Conclusions Revision surgery in otosclerosis is a challenge for otologists, but no differences in hearing outcomes between university and county clinics were found in this nationwide study. The risk of hearing deterioration and deafness is higher than in primary stapes surgery, and revision surgery should be recommended primarily in cases with a large air-bone gap and moderate to severe preoperative hearing loss.
