Summary:To evaluate the feasibility, safety and effectiveness of malleostapedotomy based on malleus-oval window technique in otosclerosis with malleus/incus mobility disorder. Six cases with malleostapedotomy on stapes footplate fixation accompanied by malleus/incus movements disorder from March 2005 to March 2007 were analyzed retrospectively, when totally 78 cases of conventional stapes surgeries were performed on isolated otosclerosis . The surgical procedures, intraoperative findings and postoperative vertigo as well as pure tone gain were discussed. All of the 6 cases showed stapes footplate fixation. Both abnormal incudomalleolar joint and incudostapedial joint were found in 2 cases. It was suspected that previous inflammation resulted in yellowish mucosa, ossicular malformation and stiffness.
