Insertion characteristics and placement of the Mid-Scala electrode array in human temporal bones using detailed cone beam computed tomography.

The aim of this study was to evaluate the insertion results and placement of the new Advanced Bionics HiFocus Mid-Scala (HFms) electrode array, inserted through the round window membrane, in eight fresh human temporal bones using cone beam computed tomography (CBCT). Pre- and post-insertion CBCT scans were registered to create a 3D reconstruction of the cochlea with the array inserted. With an image fusion technique both the bony edges of the cochlea and the electrode array in situ could accurately be determined, thus enabling to identify the exact position of the electrode array within the scala tympani.

Widening of the inferior alveolar canal: a case report with atypical lymphocytic infiltration of the nerve.

Widening of the inferior alveolar (mandibular) canal is a rare radiological finding. It is most often associated with neurofibromatosis. Rarely, a malignant process such as lymphoma may cause ill-defined enlargement of the mandibular canal.
