Myringochorda-vestibulopexy: a new method for total replacement of the ossicular chain.
A new method is described for total replacement of the ossicular chain if the ossicles are absent and malleovestibulopexy does not form a solution. One end of a 0.4-mm thick Teflon-platinum piston was fixed to the chorda tympani, and the other end was inserted into an opening made during stapedotomy. Contact between the piston and tympanic membrane was achieved by placing autologous cartilage between the posterior upper quadrant of the tympanic membrane and the chorda. The results of a second patient at 2-year follow-up are presented.
