## Indications for use
An ossicular replacement prosthesis is a device intended to be implanted for the functional reconstruction of segments of the ossicular chain and facilitates the conduction of sound wave from the tympanic membrane to the inner ear. Ossicular replacement prostheses are indicated for the functional restoration of the ossicular chain when a conductive hearing loss is present. Indications for use include: (a) Chronic middle ear disease, (b) Otosclerosis, (c) Congenital fixation of the stapes, (d) Secondary surgical intervention to correct for a significant and persistent conductive hearing loss from prior otologic surgery, and (e) Surgically correctible injury to the middle ear from trauma.
