## Indications for use
INTENDED USE: The passive middle ear implant – stapesplasty prosthesis is intended to be used for replacement of the stapes arch or stapes arch and incus in case of a fixed stapes footplate. The stapesplasty prosthesis is implanted in the middle ear to restore sound transmission from the tympanic membrane to the oval window by replacing the ossicles partially. The stapesplasty prosthesis is a medical device for single use delivered in sterile condition. INTENDED USER The stapesplasty prosthesis is intended to be implanted by qualified ENT surgeons only, with adequate skills to perform otological surgeries. Replacement of the ossicular chain is a standard surgical procedure, no additional specific device training is mandatory or required for the safe and effective use. TARGET PATIENT POPULATION The target patient population for the passive middle ear implant are patients of all ages requiring reconstruction of the ossicular chain. INDICATIONS: The stapesplasty prosthesis is indicated to treat patients with: - congenital or acquired defects of the stapes due to e.g., otosclerosis, congenital fixation of the stapes, traumatic injury, malformation of the ossicular chain or middle ear - inadequate conductive hearing from previous stapes surgery
