Effect of Sigmoid Sinus Position on the Difficulty and Approaches to Cochlear Implantation Surgery.

Objectives: To assess the effect of the position of the SS on CI regarding the ability to perform posterior tympanotomy, round window visibility, and mastoid pneumatization.

Materials And Methods: This is a prospective study, including 65 adult patients with CI performed at our center during 2017. We used 3 methods to assess SS position using a computed tomography (CT) scan.

Lateral Attic Wall Reconstruction with Glass Ionomer Bone Cement in the Management of Primary Acquired Attic Cholesteatoma in Children: A Preliminary Experience.

Objective: To assess the effectiveness of glass ionomer bone cement (GIBC) in lateral attic wall reconstruction after primary acquired attic cholesteatoma surgery.

Materials And Methods: This prospective study was conducted on twenty children collected from the ENT outpatient clinics of a secondary and tertiary hospital. All patients presented with chronic suppurative otitis media with cholesteatoma of the primary acquired attic type.

Comparison of different computed tomography post-processing modalities in assessment of various middle ear disorders.

Several anatomic structures of the middle ear are not optimally depicted in the standard axial and coronal planes. Several 2D and 3D image-processing modalities are currently available for CT examinations in clinical radiology departments. Till now 3D reconstructions of the temporal bone have not been widely used yet, and attracted only academic interest.

Sinus tympani endoscopic anatomy.

Objective: The sinus tympani has been the focus of clinical interest because of its tendency to be invaded by cholesteatoma, its visual obscurity, and the lack of a straightforward surgical approach by which it can be addressed. This study was undertaken to describe the microscopic as well as the endoscopic anatomy of the sinus tympani.

Study Design And Setting: Thirty temporal bones harvested from cadavers were dissected using an operating microscope and telescopes with different angles and 2.
