Findings in 38 revision myringoplasty operations were studied. Fascial grafts were used in all operations. The majority of immediate failures after primary procedures were found to be consequences of technical faults, i.e. poor anterior adaptation of the graft. Most of the late re-perforations were caused by atrophy of the graft without infection. The success rate for revision myringoplasty did not differ significantly from that for primary operations. It was concluded that better surgical techniques and better graft materials should be developed.
