Revision procedures in which a vein graft with a Robinson stapes prosthesis was used are reviewed in 100 patients. In all cases a wire-Gelfoam stapes prosthesis had been used initially. The surgical findings were prosthesis malfunction, 48%; eroded incus, 16%; negative findings, 14%; footplate not removed, 11%; oval window fistula, 7%; and incus problems, 4%. Postoperatively, hearing in 70.5% of the patients with conductive hearing loss was within 10 dB and 84.5% within 20 dB. The high success rate is affected by the fact that patients with conductive hearing loss were separated from those with sensorineural hearing loss, a piston prosthesis on tissue was used in the revision surgical procedure, and patients with otosclerosis regrowth did not undergo revision. Surgical directives to minimize hearing loss included use of a tissue seal over the oval window; not reopening the oval window; monitoring the patient for dizziness; performing audiometric tests during surgery; leaving the wire in place in certain cases; and not revising the prosthesis in patients with otosclerosis regrowth.

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.
