Rationale And Objectives:
The value of computed tomography was evaluated in 14 patients with persistent vertigo after otosclerosis operation.
Methods:
High-resolution computed tomography was performed with 1-mm slice thickness and table feed in the axial and coronal planes.
Results:
Computed tomography scans showed in 13 case findings that related to symptoms. An air bubble at the end of the prosthesis as a new, indirect sign of a perilymphatic fistula was found in 6 cases. An incorrect position of the stapes prostheses was diagnosed in 7 patients. One patient had recurrence of otosclerosis, and two others developed scarring around the prosthesis. In 1 case, an incus necrosis was found. Some patients showed two signs simultaneously. The computed tomography results were confirmed by retympanotomy in 12 cases.
Conclusions:
Computed tomography proved to be a valuable method in the diagnosis of persistent vertigo after otosclerosis operation. The indication for a repeat operation was facilitated by the use of computed tomography.
