Objective: To report the personalized decision-making pro- cess adopted for a cochlear implant (CI) candidate requiring magnetic resonance imaging (MRI) brain surveillance.
Study Design: Clinical capsule report.
Setting: Tertiary academic referral center.
Purposes: To investigate the effects for Ultra 3D cochlear implant (CI) positioning on MR imaging quality, looking at a comprehensive description of intracranial structures in cases of unilateral and bilateral CI placement.
Methods: Four CI angular positions (90°, 120°, 135° and 160°) at 9 cm distance from the outer-ear canal were explored. The 1.
Purposes: To primarily evaluate MRI-induced effects for Ultra 3D cochlear implantation in human cadavers in terms of artifact generation and MR image quality.
Methods: Three human cadaveric heads were submitted to imaging after unilateral and bilateral cochlear implantation. The 1.
Background: A 3D printing custom-made mask model was tested in terms of feasibility and accuracy for frameless neuronavigation during retrosigmoid approach.
Methods: A virtual 3D model of a cadaveric injected head was obtained from a high-resolution Computed Tomography (CT) scan and 3D Printed (3DP). The course of the transverse and sigmoid sinus was marked.

Purpose: In the last decades, literature has shown an increasing interest in round windows (RW) anatomy due to its pivotal role in deafness surgery. The high variability of this anatomical region, with particular regard to the round windows niche (RWN), has been studied by several authors through different methods of investigation. The aim of the present research was to radiologically examine the morphological variability of the RWN and to link the imaging findings to the endoscopic view.

In rare cases, PAN may be associated with progressive labyrinthitis ossificans (LO), an otologic emergency requiring early cochlear implantation (CI) to restore hearing before the complete, irreversible cochlear ossification. We report the first case in the literature of a patient affected by PAN with bilateral sudden sensorineural hearing loss and rapid LO who underwent "emergency" bilateral simultaneous CI.
