title: Stapedectomy revision following sensorineural hearing loss.
abstract: This study analyzes 71 stapedectomies that resulted in a sensorineural hearing loss, followed by a revision stapedectomy on the suspicion of an oval window fistula. The cases were divided between two primary stapedectomy techniques: a stainless steel Robinson prosthesis on a vein graft and a wire prosthesis with Gelfoam. The major differences between the surgical findings of the two groups were the fistula rate with the wire prosthesis was 10 times that with the Robinson prosthesis; the wire prosthesis was longer than necessary in 21% of the cases in which it was used; there was no finding of excess length with the Robinson prosthesis; and after revision stapedectomy, dizziness was lessened in 20% of the patients in the Robinson prosthesis group, in 60% of those in the wire prosthesis group, and in 75% of those with fistula. Surgical directions are given for revision stapedectomy following a sensorineural hearing loss.
