Objective: Within the field of cochlear implantation (CIs), role utilizing patient-specific anatomy for choosing optimal implant electrode is becoming increasingly important. Unfortunately, performing detailed anatomical measurements a cochlea using clinical imaging data rather time consuming and hence difficult to implement into routine. In order accelerate evaluations, previously developed mathematical models can be adjusted by measuring just few overall dimensions. However, accuracy...
In recent years, bone-attached robots and microstereotactic frames have attracted increasing interest due to the promising targeting accuracy they provide. Such devices attach a patient's skull via bone anchors, which are used as landmarks during intervention planning well. However, simulation results reveal, performance of such mechanisms is limited by errors occurring localization their anchors in preoperatively acquired computed tomography images. Therefore, it desirable identify most...
A cochlea modeling approach is presented allowing for a user defined degree of geometry simplification which automatically adjusts to the patient specific anatomy. Model generation can be performed in straightforward manner due error estimation prior actual generation, thus minimizing time. Therefore, technique well suited wide range applications including finite element analyses where geometrical simplifications are often inevitable.The method n=5 cochleae were segmented using custom...
Objective: The intracochlear position of an electrode array may influence the outcome after cochlear implantation. design can increase risk trauma causing penetration basilar membrane or shift into scala vestibuli. aim present study was to identify a scalar implantation two different arrays developed by one manufacturer. Study Design: Retrospective analysis. Setting: Tertiary referral center. Patients and Intervention: Cochlear implant recipients implanted between 2010 2014 receiving either...
Bone-attached robots and so-called microstereo-tactic frames are attracting increasing interest in the field of robot-assisted surgery due to promising targeting accuracy they provide. The authors propose a passive Stewart-Gough platform which is attached patient's head via bone anchors. It serves as an instrument guidance straight line incisions, such minimally invasive cochlear implantation. In this contribution modified version mechanism's kinematics proposed, reduces number required...
A new method for template-guided cochlear implantation surgery is proposed which has been developed to create a minimally invasive access the inner ear. first design of surgical template was drafted, built, and finally tested regarding its accuracy. For individual finalization micro-stereotactic frame bone cement utilized as this well-known well-established material suggests ease use well high clinical acceptance enables both sterile rapid handling. The concept includes an alignment device,...
Background and objective: Imaging of soft hard tissue structures inside the inner ear is necessary for development new cochlear implant electrodes their evaluation through insertion studies using human temporal bone specimens. An automated image stitching presented to enhance resolution identification structures. Methods: Thirty specimens were either embedded in white epoxy resin generating an anatomical atlas or transparent electrodes. Cross-sectional overview images corresponding magnified...
Several research groups have proposed individual solutions for surgical assistance devices to perform minimally invasive cochlear implantation. The main challenge is the drilling of a small bore hole from surface skull inner ear at submillimetric accuracy. Each group tested accuracy their device in respective test bench or number temporal bone specimens. This complicates comparison different approaches. Thus, simple and inexpensive phantom based evaluation method which resembles clinical...
