Patients' perceived outcomes after stapedectomy for otosclerosis.

We conducted a retrospective study of 29 patients who had undergone stapedectomy for otosclerosis to determine how well their subjective perceptions of hearing improvement correlated with objective audiometric measurements. Patients expressed their assessments of hearing function by completing two versions of the Hearing Disability and Handicap Scale (HDHS). One version of the HDHS was based on patients' retrospective recollections of their hearing impairment prior to surgery, and the other reflected their assessment of their current function. We evaluated these HDHS data both separately and in conjunction with pre- and postoperative audiometric findings. Following surgery, the group's mean pure-tone average improved significantly, from 58 to 27 dB--that is, the average patient had a moderately severe hearing loss preoperatively and only a mild hearing loss postoperatively. Significant improvement was also reflected in the difference between the mean pre- and postoperative HDHS scores, although some patients indicated that they experienced almost no improvement. Overall, our findings indicated that there was a relationship between objective and subjective assessments of hearing improvement following surgery, but that it was weak. Although most patients perceived significant improvement, the degree of that perceived improvement cannot be predicted from the pure-tone audiogram. We conclude, therefore, that a significant difference between audiometric findings and HDHS self-assessments is useful in identifying patients who might benefit from additional counseling and/or aural rehabilitation.
