ABSTRACT

Background and Objectives: Performing cochlear implantation is a difficult process for those patients who have received radical mastoidectomy due to chronic otitis media. However, we could perform a single stage operation successfully without external auditory meatus and mastoid complete obliteration. Materials and Methods: The authors performed 13 cases of cochlear implantation in open cavity mastoidectomy state patients without obliteration of mastoid or with the partial obliteration of mastoid from July 2011 to July 2015. Of these thirteen patients, eight patients received cochlear implantation in the site of open mastoid cavity and others in opposite site. The medical records and radiological findings were reviewed retrospectively. Results: Three of eight patients who had undergone open cavity mastoidectomy did not perform mastoid cavity oblitera-tion during cochlear implantation. Another five patients with an open cavity mastoid had undergone the partial obliteration of mastoid during cochlear implantation. There were no postoperative medical complications such as infections of mastoid cavity, recurrence of cholesteatoma and necrosis of skin flap during following up periods except for 1 case of delayed electrode extrusion. Conclusions: The advantages for this procedure as the following. First, we could overcome the difficulty of radiological diagnosis for primary or recurrent cholesteatoma due to mastoid obliteration. Second, a single-stage procedure allowed the implantation as safe as two- stage procedures. At last, non-obliterative or partial obliterative procedures may replace the typical mastoid obliteration process during cochlear implantation for it allows a safe procedure for open cavity patients reducing complications such as electrode extrusion or infection.
