Fascioperiosteal flap and neo-osteogenesis in radical mastoidectomy: long-term results.

We performed an analysis of long-term outcomes data on 60 patients with chronic otitis media with cholesteatoma who had undergone a surgical procedure based on an improved radical mastoidectomy and an inferiorly based fascioperiosteal flap. We found that at the 2-, 7-, 10-, and 13-year postoperative followup visits, all mastoid cavities were healthy and reduced in volume. At the final examination, the mean cavity volume was found to be decreased by 39% of the mean volume measured 1 month postoperatively. This reduction in volume is attributable to the neo-osteogenic activity of the flap, which was confirmed by histopathologic and radiologic findings. No recurrences took place.
