Round and oval window reinforcement for the treatment of hyperacusis

Am J Otolaryngol. Mar-Apr 2015;36(2):158-62. doi: 10.1016/j.amjoto.2014.10.014. Epub 2014 Oct 14.


Purpose: To present the outcomes of two patients (three ears) with hyperacusis treated with round and oval window reinforcement.

Materials and methods: Transcanal placement of temporalis fascia on the round window membrane and stapes footplate was performed. Loudness discomfort level testing was performed. Results of pre and post-operative hyperacusis questionnaires and audiometric testing were reviewed.

Results: Two patients (three ears) underwent surgery. Results from the hyperacusis questionnaire improved by 21 and 13 points, respectively. Except for a mild loss in the high frequencies, no change in hearing was noted post-operatively. Both patients reported no negative effects from surgery, marked improvement in ability to tolerate noise, and would recommend the procedure to others. There were no complications.

Conclusions: Round and oval window reinforcement is a minimally invasive option for treating hyperacusis when usual medical therapies fail. Further studies are needed to evaluate the effectiveness of the procedure in reducing noise intolerance.
