Background: The surgical procedure for patients with an otosclerosis is routinely the incusstapedotomy. In case of an otosclerosis with an incusnecrosis or a bony fixation of the malleus and incus, a malleostapedotomy is performed.
Patients and Methods: Since May 2002 a malleostapedotomy was performed in 6 out of 57 patients with an otosclerosis. In 2 primary cases a middle ear dysplasia was found. The malleus was fixed in 2 further primary cases. Two revision surgeries were performed presenting an incus necrosis. A titanium-piston (Titan-Piston, Storz, Tuttlingen, Germany) was used, which was fixed at the malleus handle and introduced into an opening of the footplate.
Results: The preoperative air-bone-gap was reduced from 36 dB(A) to 13 dB(A) after surgery for an average check-up time of 3 months. The length of the protheses varied from 6.5 mm to 7.5 mm. No patient showed a hearing loss or vertigo after surgery.
Conclusion: Malleostapedotomy is the technique of choice in case of an additional pathology of the ossicular chain in patients with an otosclerosis. Larger numbers of patients and long-term investigations need to compare the results of a malleostapedotomy with those of a conventional incustapedotomy.
