Fascioperiosteal flap and neoosteogenesis in radical mastoidectomy.

A surgical method, consisting of IRM and inferiorly based fascioperiosteal flap was utilized on twenty-five patients who had chronic otitis media with cholesteatoma and the long term results of the method are presented. At most, two months postoperatively, none of the patients were obligated to have any otologic care. Ear discharge, debris formation within the mastoid cavity, recurrence of cholesteatoma and/or osteitis were not encountered in the group. On the seventh year postoperatively, all of the mastoid cavities were healthy and reduced in volume. In seven years, the average volume became progressively reduced to 39% of the average volume measured one month postoperatively. This was considered to be due to the neoosteogenetic activity of the fascioperiosteal flap. This flap also provided a viable bed for a healthy epithelial layer.
