[Toton, a new total prosthesis for replacement of the ossicle chain].
After 4 years of use a new total prosthesis is proposed for replacement of the auditory ossicles, that is perfectly biocompatible since it is composed partly of the fresh autologous cartilage, which will be in contact with the drum and partly of teflon, which will be in contact with the foot of stapes. Results of a study in 44 patients, with follow up of more than 4 years in some cases, have shown: recovery of from 50 to 91% of audition in 61% and from 30 to 49% in 25% of cases, and lack of recovery in 13%. The Toton should resolve the problem of biocompatibility, a very controversial subject, and provide a solution to functional rehabilitation of empty cavities.
