Abstract

There are several procedures available for stapes surgery, including small-fenestra stapedotomy (SFS), traditional stapedectomy, and stapes mobilization. SFS is generally regarded as the procedure of first choice, in terms of the improvement of hearing level after the surgery. However, SFS is a difficult surgical procedure to Japanese, making it sometimes necessary to revert to traditional stapedectomy. Moreover, otoscierotic changes of the footplate are relatively mild in many Japanese patients, making laser techniques a viable alternative. Laser techniques allow us to perform the easy and safe stapedectomy, because cutting of the crura and fenestration of the footplate is performed without making physical contact with these structures. We found that using a Rosen suction tube to hold the quartz fiber of a KTP laser provided a sufficient field of view to allow delicate surgery to be performed. Postoperative results demonstrated the disappearance of the original A-B gap in the pure-tone audiogram. However, a temporary vertiginous feeling occurred, which may have been caused by the laser treatment slightly impairing the inner ear function.
