Comparing Gelfoam vs fat as a sealing material in stapedotomy: A prospective double-blind randomised clinical trial.

We found similarity between hearing outcome in the Gelfoam and fat as sealing materials in stapedotomy. We believe that the first limitation of this study was the short-term follow-up in stapedotomy. The other issue is that one has to be cautious when using our result, which might not be applicable in larger fenestra stapedectomy.
