Abstract

The purpose of this paper is to propose management options for cochlear implantation in chronic otitis media (COM) based on our 7-year experience. Thirteen patients with COM who were candidates for cochlear implantation were identified. COM was divided in an inactive and an active form based on clinical and radiological findings. One major complications and one minor complication were identified in the study group. In case of an active infection or in case of a unstable cavity we advise cochlear implantation as a staged procedure. A single stage procedure is recommended in case of patients with COM presenting with a dry perforation or a stable cavity.

Abstract

Laryngoplasty is well-known technique for unilateral vocal fold paralysis (UVFP). However, operation result are sometimes not as good as expected before surgery. Three-dimensional Computed tomography (3DCT) is useful for visualizing complicated intralaryngeal structures. Moreover, 3DCT is suited for analyzing the movement of the vocal fold and arytenoid cartilage because the technique is based on actual data from live patients. We have been used 3DCT of the Larynx for evaluation of UVFP before and after treatment. We uncovered some new findings about UVFP and reasons of unsatisfactory outcomes after operation. Technique and clinical applications of 3DCT for UVFP are outlined in this paper.
