Surgical findings and results of stapedectomy in patients with osteogenesis imperfecta.
Nine patients with osteogenesis imperfecta tarda and stapedial fixation (12 ears) are presented. Surgical findings as well as the immediate and long-term results of stapedectomy are described and compared with the results of previous authors. We found firmly fixed footplates in all 12 ears. Only 2 ears had thick and soft footplates. In 10 ears the stapes crura were abnormally slender and brittle, but only 1 had fractured. In 4 ears a troublesome bleeding tendency occurred during the operation. Both the immediate and the long-term hearing results were in general satisfactory.
