How we do it: modified Wehrs incus ossiculoplasty.
Keypoints * Ossiculoplasty is commonly performed as part of tympanoplasty. Hydroxyapatite is a favoured material for ossicular protheses. * A modification to the Wehrs incus prosthesis is described. * Twenty-one procedures were performed on 20 patients and the results are reported. * On average there was a 4-5 dB closure of the air-bone gap (ABG), with patients having a hearing gain procedure averaging 11 dB closure. Air-bone gap closure to <or=20 dB was achieved between 78% (0.5, 1, 2 kHz average) and 60% (0.5, 1, 2, 4 kHz average) of patients and this was stable during long-term follow-up of the ABG. * Wehrs incus prosthesis ossiculoplasty provides a reliable result following ossiculoplasty when autograft incus is not available.
