A Case of Otosclerosis Treated with One Shot Laser-Assisted Stapes Surgery

Abstract

Otosclerosis is an abnormal bone growth that causes fixation of stapes, leading to hearing loss. Several stapes surgery techniques were introduced, including stapedotomy, partial and total stapedectomy according to the extent of removal of the foot plate. Application of lasers during a stapes surgery minimizes the risk of mechanical force into the inner ear, compared to that of the conventional micro-drill or micro-pick using stapes surgery. The ideal laser technique in stapedotomy should prevent thermal damage into the perilymph. Recently, one shot laser stapedotomy technique has been reported to minimize inner ear damage compared with the multiple shot technique. We experienced one shot laser stapedotomy including resection of stapedius tendon, posterior crusectomy, and stapedotomy as selection of different power, focus size and achieved satisfactory results without complications.
