Reconstruction of the tensor tympani tendon.
We describe a case in which reconstruction of the tendon of the tensor tympani muscle was necessary for the successful restoration of sound conduction. The right ear of a nine-year-old boy was treated for cholesteatoma with staged surgery. During the first operation, the tendon was cut to ensure good visibility in the tympanic cavity. Post-operatively, maintenance of aeration of the middle ear required ventilation tubes at first and Valsalva manoeuvres later on. The position of the reconstructed tympanic membrane varied a great deal, moving between the medial wall of the tympanic cavity and extreme bulging. This made exact measurement of a columella for ossicular reconstruction impossible. The preserved handle of the malleus was bound to the cochleariform process with ionomer cement, using a piece of surgical suture material as a substitute for the tendon. This arrangement prevented the tympanic membrane from undergoing excessive lateral movement after inflation and the ossicular chain was replaced with a successful ossiculoplasty with an autogenous bone 'drum to footplate' columella. The pre-operative 55.0 dB air-bone gap decreased immediately to 3.3 dB, widening after three years to 15.0 dB.
