[Postoperative complication in stapedectomy: excessive introduction of the prothesis in the oval window]

Postoperative failures and complications detected in patients who undergo surgery for otosclerotic disease are not uncommon in stapes surgery. Prosthesis displacement and incus necrosis are the most common findings in review stapedectomy. We report the case of a patient who had tinnitus, vertigo, and non-recovery of air conduction thresholds without neurosensorial lesions after stapes surgery. The suspected diagnosis of excessive introduction of the prosthesis in the oval window was confirmed by computed tomography, which showed the radio-opaque image of the McGee metal prosthesis. The prosthesis replacement and literature review are discussed.
