Abstract

Objective 

To compare the outcomes of patients with unilateral otosclerosis treated consecutively by a hearing aid then stapedotomy.


Study Design 

Monocentric, nonrandomized, prospective, longitudinal, cohort study.


Setting 

Tertiary university hospital.


Patients 

Adult patients with a unilateral conductive hearing loss of at least 30 dB caused by otosclerosis.


Interventions 

Consecutive treatment by an external hearing aid followed by stapedotomy.


Main Outcome Measures 

Differences between hearing aids and stapedotomy in quality of life, pure-tone audiometry, binaural hearing, tinnitus severity, and patient satisfaction.


Results 

Twenty-two patients were included, of which 20 (91%) underwent stapedotomy. Stapedotomy demonstrated increased quality of life according to Glasgow Health Status Inventory scores versus hearing aids (+10.4 ± 9.4 [p = 0.0001]). Stapedotomy versus hearing aids showed improved pure-tone averages (−11.1 ± 11.0 dB [p = 0.002]) and air-bone gaps (−11.8 ± 10.7 dB [p = 0.0006]). Stapedotomy was superior to hearing aids for speech-in-noise recognition in the reverse dichotic condition (−8.4 ± 26.9 dB [p = 0.004]) and showed improved sound localization accuracy in root mean square error (−14.5 ± 24.5 degrees [p = 0.02]). Stapedotomy, but not hearing aids, showed improved patient self-evaluated tinnitus after baseline adjustment according to the Tinnitus Handicap Inventory (−8.0 ± 13.4 [p = 0.02]) and visual analog scale for tinnitus intensity (−28.7 ± 34.1 [p = 0.006]). Overall, patients were more satisfied with surgery versus hearing aids.


Conclusions 

Stapedotomy remains more effective compared with hearing aids with greater improvements in quality of life, patient satisfaction, hearing outcomes, and self-evaluated tinnitus.
