Objective To assess the functional performance of remodeled malleus allografts in a malleus‐footplate assembly in terms of hearing results and mid long‐term stability.
Study Design A retrospective study of 60 consecutive patients who underwent a malleus allograft ossiculoplasty from 1993 until 2000. In all cases the incus and the stapedial arch were missing as the result of cholesteatoma (49), chronic otitis (5), incus necrosis resulting from stapes prosthesis (5), and congenital ossicular malformations (1). In all cases malleus allografts were remodeled to form a malleus‐stapes assembly.
Results The audiometric results, using such an ossiculoplasty, revealed an overall median gain of 18.3 dB at 2 months, 22.3 dB at 6 months, and 25 dB 1 year postoperatively on Fletcher frequencies. An air‐bone gap closure within 20 dB was achieved in 81% of all cases 1 year postoperatively. No cases of extrusion have been seen in our series.
Conclusion Our findings suggest that malleus allografts are capable of generating good and stable funcitonal results as malleus‐stapes assembly.
