[Tympanic membrane prosthesis using soft magnetoelastomer]

This paper presents a new method for tympanum prosthesis application. The prosthesis is fixed by the interaction of magnetic pondermotive forces between two soft petals of a magnetoelastomer. This type of prosthesis was applied to 30 patients with dry perforative otitis media, aged 51-75 years. The intervention was performed in the outpatient department. Prostheses are recommended to be replaced every 3 months. These patients showed good tolerance of the treatment, which significantly improved their hearing level. The method of prosthesis fixation was reliable and atraumatic.
