The purpose of this paper is to present the indications for and the technique and results of using an incus replacement prosthesis in the otosclerotic ear (Fig 1). Essentially, it represents a progress report, inasmuch as the early results in both the fenestrated and nonfenestrated ear have been reported previously.1,2
