[Anatomical and functional results of middle ear reconstruction with tympano-ossicular allografts]

Twenty five patients with severely damaged middle ears underwent reconstructive surgery with using total tympano-ossicular allografts. Two years long follow-up showed average air-bone gap about 20 dB or better in 44% of patients. Materials and methods used for reconstruction in two groups (part I and II) were compared, basing on anatomical and functional results. In patients with total perforation and lack of malleus, reconstruction with the tympanic membrane allograft attached to the malleus handle and shaped incus columella revealed long-term hearing results improvement (63.6% closure of air-bone gap within 20 dB) better than in similar patients with a total tympano-ossicular allograft (44% closure of the air-bone gap within 20 dB) during 2 years long follow-up.
